•
•
Determining the Software Version
To determine the version of Cisco MDS SAN-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log in to the switch and enter the show version EXEC command.
To determine the version of Cisco MDS SAN-OS software currently running on a Cisco MDS 9000 Family switch using the Fabric Manager, view the Switches tab in the Information pane, locate the switch using the IP address, logical name, or WWN, and check its version in the Release column.
Note
Downloading Software
The Cisco MDS SAN-OS software is designed for mission-critical high availability environments. To realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend that you install dual supervisor modules.
To download the latest Cisco MDS SAN-OS software, access the Software Center at this URL:
http://www.cisco.com/public/sw-center
See the following sections in this release note for details on how you can nondisruptively upgrade your Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Fabric Manager to perform the upgrade, enables the compatibility check. The check indicates if the upgrade can happen nondisruptively or disruptively depending on the current configuration of your switch and the reason.
Compatibility check is done:Module bootable Impact Install-type Reason------ -------- -------------- ------------ ------1 yes non-disruptive rolling2 yes disruptive rolling Hitless upgrade is not supported3 yes disruptive rolling Hitless upgrade is not supported4 yes non-disruptive rolling5 yes non-disruptive reset6 yes non-disruptive resetAt a minimum, you need to disable the default device alias distribution feature using the no device-alias distribute command in global configuration mode. The show incompatibility system bootflash:1.3(x)_filename command determines which additional features need to be disabled.
Note
Note
Selecting the Correct Software Image for an MDS 9100 Series Switch
The system and kickstart image that you use for an MDS 9100 series switch depends on which switch you use, as shown in Table 3.
Selecting the Correct Software Image for an MDS 9500 Series Switch
The system and kickstart image that you use for an MDS 9500 Series switch depends on whether the switch is based on a Supervisor-1 module or a Supervisor-2 module, as shown in Table 4.
Use the show module command to display the type of supervisor module in the switch.
For a Supervisor-1 module, the output might look like this:
switch# show moduleMod Ports Module-Type Model Status--- ----- -------------------------------- ------------------ ------------......5 0 Supervisor/Fabric-1 DS-X9530-SF1-K9 active*6 0 Supervisor/Fabric-1 DS-X9530-SF1-K9 ha-standbyFor a Supervisor-2 module, the output might look like this:
switch# show moduleMod Ports Module-Type Model Status--- ----- -------------------------------- ------------------ ------------......7 0 Supervisor/Fabric-2 DS-X9530-SF2-K9 active *8 0 Supervisor/Fabric-2 DS-X9530-SF2-K9 ha-standbyMigrating from Supervisor-1 Modules to Supervisor-2 Modules
As of Cisco MDS SAN-OS Release 3.0(1), the Cisco MDS 9509 and 9506 Directors support both Supervisor-1 and Supervisor-2 modules. Supervisor-1 and Supervisor-2 modules cannot be installed in the same switch, except during migration. Both the active and standby supervisor modules must be of the same type, either Supervisor-1 or Supervisor-2 modules. For Cisco MDS 9513 Directors, both supervisor modules must be Supervisor-2 modules.
Caution
Note
To migrate from a Supervisor-1 module to a Supervisor-2 module, refer to the step-by-step instructions in the Cisco MDS 9000 Family CLI Configuration Guide.
Configuring Generation 2 Switching Modules
The Cisco MDS 9500 Multilayer Directors are designed to operate with any combination of Cisco MDS 9000 Generation 1 and Generation 2 modules. However, there are limitations to consider when combining the various modules and supervisors in the Cisco MDS 9500 Series platform chassis. The references listed in this section provide specific information about configurations that combine different modules and supervisors.
For information on configuring Generation 2 switching modules, refer to:

Use Table 5 to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.1(3). Find the image release number you are currently using in the Current column of the table and use the path recommended.
Note
Use Table 6 to determine your FICON nondisruptive upgrade path to Cisco MDS SAN-OS Release 3.1(3). Find the image release number you are currently using in the Current Release with FICON Enabled column of the table and use the path recommended.
Note
Upgrading with IVR Enabled
An Inter-Switch Link (ISL) flap resulting in fabric segmentation or a merge during or after an upgrade from Cisco MDS SAN-OS Release 2.0(x) to a later image where IVR is enabled might be disruptive. Some possible scenarios include the following:
•
•
•
If this problem occurs, syslogs indicate a failure and the flapped ISL could remain in a down state because of a domain overlap.
This issue was resolved in Cisco SAN-OS Release 2.1(2b); therefore, you must upgrade to Release 2.1(2b) before upgrading to Release 3.1(3). An upgrade from Cisco SAN-OS Releases 2.1(1a), 2.1(1b), or 2.1(2a) to Release 2.1(2b) when IVR is enabled requires that you follow the procedure below, and then follow the upgrade guidelines listed in the "Upgrading Your Version of Cisco Fabric Manager" section. If you have VSANs in interop mode 2 or 3, you must issue an IVR refresh for those VSANs.
To upgrade from Cisco SAN-OS Releases 2.1(1a), 2.1(1b), or 2.1(2a) to Release 2.1(2b) for all other VSANs with IVR enabled, follow these steps:

Note
Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.1(3)
Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode, which is the default for releases prior to Release 3.0(1).
Note
For more information on upgrading SAN-OS software, see the "Upgrading Your Cisco MDS SAN-OS Software Image" section.
If the configuration is not updated before the upgrade, the installation process for the new image will automatically convert all ports configured in auto mode to Fx mode. This change in mode might cause a disruption if the port is currently operating in E mode.
To upgrade the image on your SSM without any traffic disruption, follow these steps:
Step 1

Caution
Upgrading a Switch with Insufficient Space for Two Images on the Bootflash
To upgrade the SAN-OS image on a Cisco MDS 9000 Family switch requires enough space on the internal CompactFlash (also referred to as bootflash) to accommodate both the old software image and the new software image.
As of Cisco MDS SAN-OS Release 3.1(1), on MDS switches with a 256-MB CompactFlash, it is possible in some scenarios that a user might be unable to fit two images on the bootflash. This lack of space on the bootflash might cause the upgrade process to fail because new images are always copied onto the bootflash during an upgrade.
The following MDS switches are affected by this issue:
•
•
•
To work around an image upgrade failure caused by a lack of space on the bootflash, follow these steps:
Step 1
Step 2
switch# delete bootflash:m9200-ek9-mz.3.0.3.bin
Note
switch# delete bootflash://sup-standby/m9500-sf1ek9-mz.3.0.3.binStep 3
Step 4
Step 5
Upgrading a Cisco MDS 9124 Switch
If you are upgrading from Cisco MDS SAN-OS Release 3.1(1) to Cisco SAN-OS Release 3.1(3) on a Cisco MDS 9124 Switch, follow these guidelines:
•
•
•
•
•
•
Performing a Disruptive Upgrade on a Single Supervisor MDS Family Switch
Cisco MDS SAN-OS software upgrades are disruptive on the following single supervisor Cisco MDS Family switches:
•
•
•
If you are performing an upgrade on one of those switches, you should follow the nondisruptive upgrade path shown in Table 5, even though the upgrade is disruptive. Following the nondisruptive upgrade path ensures that the binary startup configuration remains intact.
If you do not follow the upgrade path, (for example, you upgrade directly from SAN-OS Release 2.1(2b) to SAN-OS Release 3.1(3)), the binary startup configuration is deleted because it is not compatible with the new image, and the ASCII startup configuration file is applied when the switch comes up with the new upgraded image. When the ASCII startup configuration file is applied, there may be errors. Because of this, we recommend that you follow the nondisruptive upgrade path.
Downgrading Your Cisco MDS SAN-OS Software Image
This section lists the guidelines recommended for downgrading your Cisco MDS SAN-OS software image and contains the following sections:

As of Cisco MDS SAN-OS 3.1(3), the ability to detect a faulty CompactFlash is built into the SAN-OS software. A new CompactFlash cyclic redundancy check (CRC) checksum test can check the state of the CompactFlash firmware on select modules. If the CompactFlash firmware is not corrupted, then the SAN-OS software can automatically update the CompactFlash firmware.
By default, the new CompactFlash CRC checksum test is enabled to automatically run in the background every seven days. New command-line interface (CLI) commands allow you to run the test on demand, change the automatic test interval, and disable the automatic testing.
The CompactFlash CRC checksum test can check if an affected CompactFlash is corrupted on the following modules:
•
•
•
•
•
•
If a CompactFlash is found to be corrupted, then the CRC checksum test is retried five times. If it fails five consecutive times, then the system initiates a failure action. The type of action depends on the module where the failure occurred:
•
•
•
•
During a software upgrade to Cisco MDS SAN-OS 3.1(3), all modules that are online are tested and the installation stops if any modules are running with a faulty CompactFlash. When this occurs, the switch cannot be upgraded until the situation is corrected. A system message displays the module information and indicates that you must issue the system health cf-crc-check module command to troubleshoot the problem.
Note
The Cisco Fabric Manager CompactFlash Check Utility that was included in previous Fabric Manager 3.1(x) releases, is not included in Cisco MDS SAN-OS Release 3.1(3).For complete configuration information about the CompactFlash CRC checksum test feature, refer to the Cisco MDS 9000 Family CLI Configuration Guide. For descriptions of new commands supported by the CompactFlash checksum feature, refer to the Cisco MDS 9000 Family Command Reference.
System Default Port Mode F
As of Cisco SAN-0S Release 3.1(3), a new CLI command allows you to globally change the mode of Fibre Channel ports whose default mode is Auto, while avoiding traffic disruption caused by the formation of unwanted inter-switch links (ISLs). The new system default switchport mode F command sets the administrative mode of ports to mode F, while switch operation remains graceful. No ports are flapped.
This command changes the configuration to administrative mode F of the following ports:
•
•
This command does not affect the configuration of the following ports:
•
•
Note
If you downgrade from Cisco MDS SAN-OS Release 3.1(3) to any earlier SAN-OS release after you execute the system default switchport mode F command, the ports retain the configuration that resulted from the execution of the command. In other words, the ports do not revert back to the mode they were in prior to executing the command. In addition, the system default switchport mode F command is not available in SAN-OS releases lower than Cisco SAN-OS Release 3.1(3).
For additional information, refer to the Cisco MDS 9000 Family CLI Configuration Guide and the Cisco MDS 9000 Family Command Reference.
Changes in SAN Device Virtualization
Cisco SAN-OS Release 3.1(3) supports the following features of SAN Device Virtualization:
•
•
For additional information, refer to the Cisco MDS 9000 Family CLI Configuration Guide.
User Interface Changes in Cisco Fabric Manager
In Cisco SAN-OS Release 3.1(3), there are no changes in the user interface of Cisco Fabric Manager.
Maximum Number of Flows Increased in Cisco Fabric Manager
As on Cisco Fabric Manager Release 3.1(2c) and Cisco SAN-OS Release 3.1(3), the Flow Creation wizard has increased the maximum number of flows per switch from 2048 to 10000.
Fabric Manager Login Procedure
As of Cisco SAN-OS Release 3.1(1), logging into Fabric Manger is a two-part process that involves entering your username and password twice, in two different dialog boxes. To successfully complete the login process, you must:
•
•

Limitations and Restrictions
This section lists the limitations and restrictions for this release.
Using SAN Device Virtualization on Cisco Fabric Switches
There must be at least one SAN device virtualization-enabled switch that is not a Cisco MDS 9124 switch, a Cisco Fabric Switch for HP c-Class BladeSystem, or a Cisco Fabric Switch for IBM BladeCenter between the server and the target that are being virtualized. In other words, SAN device virtualization does not work when initiators and primary targets are connected to the same Cisco MDS 9124 Switch or Cisco Fabric Switch for HP c-Class BladeSystem or Cisco Fabric Switch for IBM BladeCenter.
Interface Names on Cisco Fabric Switches and Interface Based Zoning
The Cisco Fabric Switch for HP c-Class BladeSystem and the Cisco Fabric Switch for IBM BladeCenter use different Fibre Channel interface names than those used on MDS 9000 Family switches. Interface names are used in many operations, including domain interface zoning.
Note
Table 9 shows the mapping between the internal interface names and the displayed interface names on the Cisco Fabric Switch for HP c-Class BladeSystem and the Cisco Fabric Switch for IBM BladeCenter to the displayed interface names.
CWDM SFPs
The 2-Gbps CWDM SFPs do not have have a maximum speed set in memory and they negotiate to 4-Gbps on modules that support the higher speed. As a result, the link comes up and appears to work, but then becomes disabled and connectivity problems occur. To correct this problem, both sides of the connection must have their speed hard coded to 2-Gbps.
Fabric Manager
Observe the following limitations or restrictions for the Cisco SAN-OS Release 3.1(3) for Fabric Manager:
•
•
•
iSNS
Observe the following behaviors regarding the iSNS server and client:
•
•
•
•
•
MTU Size Limitation
The Cisco MDS 9216i switch and MPS-14/2 module do not support an MTU size greater than 8000 bytes. An attempt to set the MTU size greater than 8000 bytes will result in an error. As a workaround, reset the value of the MTU size (576 to 8000 bytes) and issue the no shutdown command on the interface for normal operation.
Reconfiguring SSM Ports
Starting with Cisco MDS SAN-OS Release 3.0(1), the SSM front panel ports can no longer be configured in auto mode, which is the default for releases prior to Release 3.1(1). For instructions about how to modify the configuration of the ports before upgrading to SAN-OS Release 3.1(3), see the "Reconfiguring SSM Ports Before Upgrading to SAN-OS Release 3.1(3)" section.
Virtual Router Redundancy Protocol (VRRP) Interfaces
When a switchover occurs on a switch that is the master for Virtual Router Redundancy Protocol (VRRP) interfaces, the switchover may cause a minor delay. As a result, the VRRP backup (occurring elsewhere) may assume the role of the VRRP master. As a workaround, increase the VRRP advertisement interval for these interfaces.
QoS on an MDS 48-port Fibre Channel Module
Due to possible differences in parts per million between the MAC ASICs on both sides of an ISL link, there is a potential throughput issue when running QoS over an ISL on an MDS 48-port Fibre Channel module. Specifically, the user may not see traffic throughput that follows the programmed QoS ratios. The throughput ratio on the high and/or medium priority class of service (COS) relative to the low priority COS, may not be as high as the actual programmed ratio.
If this situation occurs, you can move the ISL to a port on a different port group on one and/or both sides of the link, or move the ISL to a port on a lower-density card if you require accurate QoS ratios.
Maximum Number of Zones Supported in Interop Mode 4
In interop mode 4, the maximum number of zones that is supported in an active zone set is 2047, due to limitations in the connected vendor switch.
When IVR is used in interop mode 4, the maximum number of zones supported, including IVR zones, in the active zone set is 2047. The limit for the maximum number of IVR zones per VSAN is 250 zones (two members per zone).
Configuring Default Settings for the Default Zone
Following an upgrade from any Cisco SAN-OS 2.x release to any Cisco SAN-OS 3.x release, the configuration defined by the zone default-zone permit vsan vsan-id command is applied only to the active VSAN. The configuration does not apply to unconfigured VSANs. In SAN-OS 3.x, you can apply the configuration to unconfigured VSANs by issuing the system default zone default-zone permit command.
Similarly, the zoneset distribute full vsan vsan-id command applies only to the active VSAN following an upgrade from any Cisco SAN-OS 2.x release to any Cisco SAN-OS 3.x release.
Although you can configure the default-zone settings in the setup script, these settings do not take effect for VSAN 1, because VSAN 1 already exits prior to running the setup script. To configure the default settings for the default-zone in VSAN 1, you must explicitly enter the zone default-zone permit command.

1 This issue was resolved in Cisco Fabric Manager Release 3.1(2c). For additional information, refer to the Release Notes for Cisco MDS 9000 Family Fabric Manager Release 3.1(2c).
Resolved Caveats
•
Symptom: As a consequence of possible spanning-tree errors, the Cisco MDS 9124 Switch, the Cisco Fabric Switch for HP c-Class BladeSystem, and the Cisco Fabric Switch for IBM BladeCenter stop responding to Telnet and ping commands on the management Ethernet port.
Workaround: This issue is resolved.
•
Symptom: If there is an interruption to the upgrade process on a given module during an upgrade to Cisco MDS SAN-OS Release 3.1(2), the install all command will fail. This may result in a condition where some modules and supervisors are running SAN-OS 3.1(2) and the remainder of modules in the chassis are running an older version of SAN-OS. You may not be able to execute the install all command again to upgrade the remaining modules to SAN-OS 3.1(2).
If you issue the show install all status command, you may see the following types of messages in the install logs:
Module X: Upgrading Bios/loader/bootrom.
Warning: please do not remove or power off the module at this time.
-- FAIL. Return code 0x40710001 (BIOS versions are identical).
CAUTION: The BIOS/loader/bootrom of above module may be in corrupted state. Please try programming it again and DO NOT reboot without programming it successfully, otherwise you have to manually take out the flash from the card and program it in a BIOS programming station.
Install has failed. Return code 0x40930015 (Pre-upgrade of a module failed).Please identify the cause of the failure, and try 'install all' again.Workaround: This issue is resolved.
•
Symptom: On a 4-Gbps Fibre Channel module, PLOGI accepts were discarded because the port was initially an F port, but had been changed to an E port.
Workaround: This issue is resolved.
•
Symptom: Following an upgrade to Cisco SAN-OS Release 3.1(2), the version information that is managed per module by the system access control list (ACL) software component on the active supervisor has the new, correct version information, but the standby supervisor has the old, incorrect version information. After a system switchover, the standby supervisor becomes the active supervisor, but it has the wrong system ACL module version information. As a result, traffic is disrupted for any new IVR flows that are programmed or modified from that point onwards. Existing IVR flows are not affected.
Workaround: This issue is resolved.
•
Symptom: Using unknown usernames or passwords in Cisco Fabric Manager can result in multiple Access Control Server (ACS) accesses and can lock users out of the fabric, if your ACS policy disables users when multiple incorrect passwords are used in succession.
Workaround: This issue is resolved.
•
Symptom: In rare situations, an upgrade to Cisco MDS SAN-OS 3.0(3) or higher may cause an MDS 9000 16-port Fibre Channel switching module to reload during the upgrade process. After the upgrade image is loaded on the module, a memory manager process reads the hardware to restore itself to its pre-upgrade state. While doing so, it finds an invalid entry in memory and then crashes while trying to process that entry. As a result, the module reloads, which clears the invalid entry and the module then comes up fully operational. However, the module reload may abort the upgrade process and the remaining modules may require manual upgrades.
You may see syslog messages similar to the following:
2007 Apr 2 11:15:35 MDS1 %IMAGE_DNLD-SLOT1-2-IMG_DNLD_STARTED: Module image

•
Symptom: If an interface index map is not programmed correctly, the Port Manager continues to bring up the port, which results in an ACL programming failure and the following error message:
%ZONE-2-ZS_TCAM_PROGRAMMING_FAILED: %$VSAN xxx%$ TCAM operation failed : Unknown, Reason: idxmap ioctl failureBecause of the programming failure, the port is effectively useless, even though it is up.
Workaround: This issue is resolved.
•
Symptom: Installation of the Oracle Express database fails if you are running Microsoft Windows 2000 and using the Hypersonic SQL database with Cisco Fabric Manager.
Workaround: This issue is resolved.
•
Symptom: If there are IVR-NAT rewrite rules for FCIP interfaces on an MDS 9000 MPS-14/2 module in an IVR border switch, updates or modifications of the rewrite rules may fail after the MPS-14/2 module is upgraded to SAN-OS 3.1(2x) or lower. Stale IVR-NAT rules are left on the FCIP interfaces rather than the required IVR-NAT rules, and this impacts IVR traffic over the FCIP link.
There is no impact on traffic unless and until IVR rewrite rules need to be modified after an upgrade. However, if the IVR rewrite information changes (such as when a virtual domain ID changes) because of other events taking place in the fabric, then the stale IVR rewrite rules continue to re-write the frames entering the FCIP interface with the old rewrite information. This may result in frames with an invalid rewritten destination ID getting dropped or incorrectly forwarded in the network. Frames with a source ID that is incorrectly rewritten will eventually be rejected or incorrectly interpreted by the destination device.
Workaround: This issue is resolved.
•
Symptom: In SAN-OS 3.1(2b), if you authenticate users against a TACACS+ server, Fabric Manager tries the second and third AAA servers, even though authentication against the first server was successful.
Workaround: This issue is resolved.
•
Symptom: When enhanced zoning is enabled, an empty pop-up window displays in Fabric Manager after a zone set activation completes.
Workaround: This issue is resolved.
•
Symptom: For security reasons, the addUser file should require a database password.
Workaround: This issue is resolved.
•
Symptom: A # symbol should be added to the front of the AAA.properties and server.properties keys so that they can be decoded with a private key.
Workaround: This issue is resolved.
Open Caveats
•
Symptom: If you are running Cisco MDS SAN-OS Release 3.1(2b) and you are using FCIP tape acceleration, you may experience intermittent FCIP link flaps.
Workaround: Disable FCIP tape acceleration.
•
Symptom: An FCIP link running tape acceleration may flap and dump its core when a malfunctioning host repeatedly asks for a status from the tape.
Workaround: Shut down the malfunctioning host switch.
•
Symptom: If you bring up more than one link at a time between two VSANs that have overlapping domains and at least one of the switches is SDV enabled, one link will become isolated. The other links will come up, even though the domains are overlapping. In addition, the SDV virtual domains will change, causing traffic disruption on all devices associated with their old value.
Workaround: Bring up multiple links between two switches one at a time. Verify that the first link came up correctly before attempting to bring up the next link. If the first link fails to come up because of a domain ID overlap, resolve the domain conflict and then try again to bring up the links
•
Symptom: 100% CPU utilization was seen on an MDS switch. It was caused by repeated fabric logins (FLOGIs) on a particular port. This situation can occur if a host cannot log in because the allocation of the FC ID fails, and keeps re-trying using a specific pattern of Source FC IDs (S_IDs) for the FLOGI frame.
Workaround: The interface will now be error-disabled for too many FLOGI failures.
To troubleshoot the configuration and find the reason for the FC ID allocation failure, examine the messages in the syslog. Refer to the Cisco MDS 9000 Family CLI Configuration Guide for detailed information about FLOGI, FC IDs, and FC ID allocation for HBAs.
•
Symptom: FCIP links may fail on an MDS 9216i switch that has compression set to auto when the other end of the FCIP link is terminated by an IPS-8 module. You may see the following message in the logs:
%IPS_SB_MGR-SLOT1-3-CRYPTO_FAILURE: Heartbeat failure in encryption engine (error 0x1)
%ETHPORT-5-IF_DOWN_SOFTWARE_FAILURE: Interface GigabitEthernet1/1 is down (Port software failure)
%PORT-5-IF_DOWN_SOFTWARE_FAILURE: %$VSAN 1%$ Interface fcip99 is down (Port software failure)Workaround: If both ends of an FCIP link are not on an MPS-14/2 module, do not use mode 1 and auto.
•
Symptom: Backups of IBM Tivoli Storage Manager (TSM) running AIX might fail when using FCIP tape acceleration if the tape sends an end-of-tape status while FCIP tape acceleration has partially buffered write commands.
Workaround: Disable FCIP tape acceleration.
•
Symptom: Under some circumstances, disabling the CIM Server does not terminate the CIM Server process, which causes further enabling or disabling of the CIM Server to be ineffective.
Workaround: None.
•
Symptom: A virtual initiator is configured with the host's port world wide name (pWWN), and the virtual initiator and virtual target logical unit numbers (LUNs) are zoned in the active zone set. When you issue the show incompatibility system bootflash: command, the switch does not display the incompatibility.
Workaround: None.
•
Symptom: If you upgrade a system with a modem configuration to Cisco MDS SAN-OS Release 3.x, the upgrade fails and the system reboots.
Workaround: Prior to the upgrade, remove the modem configuration. When the upgrade is finished, reconfigure the modem.
If the modem connection is through a COM1 port, follow these steps to remove the configuration and then reconfigure it:
1.
switch#config t
switch(config)#2.
switch(config)#line com1
switch(config-com1)#3.
switch(config-com1)#no modem in4.
switch(config-com1)#modem inIf the modem connection is through the console port, follow these steps to remove the configuration and then reconfigure it:
1.
switch#config t
switch(config)#2.
switch(config)#line console
switch(config-console)#3.
switch(config-console)#no modem in4.
switch(config-console)#modem in•
Symptom: If you install a feature license on any module, then the storage services module (SSM) with the SCSI flow feature will be reprovisioned and write acceleration on the flows will be affected.
Workaround: To work around this issue, please contact Cisco TAC. They can help you recover from this problem by guiding you through the following steps:
1.
2.
3.
4.
5.
•
Symptom: FCIP links running read acceleration might fail in certain circumstances due to a defect in error handling.
Workaround: Disable FCIP tape acceleration.
•
Symptom: A crash might occur in the intelligent line card (ILC) helper process when provisioning or deprovisioning a storage application on the SSM card.
Workaround: If the ILC helper dumps core memory three times, reboot the switch for it to function normally. Use the show cores command to determing if the ILC helper has dumped core memory.
•
Symptom: In rare situations, data virtual target (DVT) configurations might disappear following a reload of the SSM or an upgrade to the SSI 3.1(2m) image.
Workaround: Statically define the DVTs using the santap module command, as in the following example:
switch(config)#santap module slot-number dvt target-pwwn target-pwnn target-vsan target-vsan-id dvt-name dvt-name dvt-vsan dvt-vsan-id lun-size-handling 1•
Symptom: Spectra Logic tape drives require a unique area ID.
Workaround: Add the company OUI ID to the swtich database so that the switch can assign unique area IDs to the Spectra Logic tape drives.
•
Symptom: If the tape sends a certain error status without requesting status confirmation, the FCIP link may flap.
Workaround: Disable FCIP tape acceleration.
•
Symptom: When you configure Cisco Traffic Analyzer to capture traffic on one or more interfaces on a Windows platform, the configuration web page might not show that the interface has been selected for traffic capture even though traffic capture on that interface is enabled.
Workaround: Check the logs to clarify that the correct interface has been selected.
•
Symptom: If an iSNS client tries to register a portal separately after registering the network entity and storage node object with the Cisco MDS iSNS server, the portal registration might fail.
Workaround: Register the portal at the same time as the network entity and storage node object registration.
•
Symptom: If there are IP over Fibre Channel (IPFC) interfaces configured on an SSM, you might experience issues if you downgrade from SAN-OS Release 3.x to Release 2.x.
Workaround: Before downgrading, remove the IPFC interface on the module and then recreate the IPFC interface after the downgrade is complete.
•
Symptom: Time zone changes that are executed on an MDS switch do not take effect on the 12-port, 24-port, and 48 port 1-Gbps/2-Gbps/4-Gbps Fibre Channel modules, and on the 4-port 10-Gbps module. This issue occurs in SAN-OS Releases 3.0(1), 3.0(2), 3.0(2a), and 3.0(3).
Time zone changes that are executed on an MDS switch do not take effect on the 16-port or 32-port 1-Gbps/2-Gbps module, on the 4-port or 8-port Gigabit Ethernet IP services module, the MPS 14/2 module, and on the SSM. This issue occurs in SAN-OS Release 3.0(3).
This issue has no effect on functionality. However, debug messages and syslogs from the MDS switching modules have incorrect timestamps if the time zone is configured on an MDS switch.
Workaround: None.
•
Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic.
Workaround: Increase the fspf cost on the link before it is shut down, so that traffic will flow through an alternate path.
•
Symptom: On an MDS switch with dual supervisor modules, the bootflash on the standby supervisor is replaced with a new bootflash. Then there is a system switchover. Then the bootflash on the new standby supervisor (which was previously the active supervisor) is replaced. The copy running-config startup-config command is used to save the configuration, but the console speed does not get saved. Instead, the console speed is reset to 9600.
Workaround: After you replace the bootflash and the standby supervisor boots up, issue the copy running-config startup-config command to synchronize the configuration from the active supervisor to the standby supervisor.
•
Symptom: An association call from a VSAN to its logical switch returns a particular WWN, but an association call from the physical system to the virtual system does not return the same WWN, which indicates that the logical switch is not associated to the physical switch.
Workaround: None.
•
Symptom: Under rare circumstances, a customer running the Cisco MDS SAN-OS SANTap feature with EMC RecoverPoint might find that following a reload of the SSM module, the SSM CVT is stuck in UNKNOWN status in the RecoverPoint appliance.
Workaround: None.
•
Symptom: Memory leaks in the CIM Server could eventually result in the process terminating or becoming unresponsive.
Workaround: None. All known resource leaks in the CIM Server have been fixed. However, some growth in the process size can still be observed when repeatedly executing queries that retrieve large amounts of data.
•
Symptom: Following a fabric reconfiguration, if you use Fabric Manager Server to discover the fabric and you check the Accelerate Discovery check box on the Discover New Fabric dialog box, some VSANs are segmented by Fabric Manager Server. VSANs may be segmented because they are isolated or down.
Workaround: From Fabric Manager Server, close the fabric and then re-open it without checking the Accelerate Discovery check box on the the Discover New Fabric dialog box.
•
Symptom: When creating a new VSAN through Fabric Manager or through a script that can create a VSAN on each switch at the same time, the same domain ID is created for each switch. This causes the newly-created VSAN to be segmented on all links.
Workaround: Either create the VSAN using static domain IDs, or use the CLI to create new VSANs at different times.
•
Symptom: An MDS switch that provides IVR routing on a local VSAN may not be able to export new devices via IVR if there are multiple IVR routers in the local VSAN or if one IVR router contains stale entries for a device. When an IVR router has stale information, it will be out of sync with the other IVR routers. Because IVR routers work in sync, then IVR cannot export any new devices.
Workaround: Enable and disable IVR on the MDS switch that is the link state ready (LSR) owner.
•
Symptom: An SNMP Get-Next Request for the MIB object ip.ipAddrTable.ipAddrEntry.ipAdEntIfIndex on an MDS 9000 switch resolves by asking ifIndex for a loopback address. Because there is no hardware (ifIndex) for a loopback address, the ifIndex reply for this interface is skipped and the next possible instance of the object, which is IP-MIB::ipAdEntNetMask, is returned.
Workaround: There are two ways you can work around this issue. Do one of the following:
–
–
•
Symptom: A fibre channel port on an MDS switching module remained out-of-service after the port was put back in service. As a result, it was not possible to configure the port.
Workaround: To put the module back in service, enter the commands shown in this example:
switch(config)#poweroff module slot-number
switch# purge module slot-number running-config
switch(config)# no poweroff module slot-numberConfigure the module again because the previous configuration will be lost.
•
Symptom: When Microsoft Challenge Handshake Authentication Protocol (MSCHAP) is enabled, NAS-IP is not sent. When Password Authentication Protocol (PAP) is used, NAS-IP is sent. PAP is the default authentication protocol.
Workaround: None.
•
Symptom: Following a Cisco SAN-OS software upgrade or downgrade, certain ports get stuck in link failure or in a not-connected state, even though the same SFP, cable, host, or storage device works in other ports on the same module.
Workaround: Reload the module, or contact Cisco TAC for a less disruptive workaround.
•
Symptom: When an fcalias is added as a zone member or a zone is added to a zone set via SNMP, there is an SNMPD memory leak.
Workaround: None.
•
Symptom: A data path processor (DPP) might fail on an MDS switch running Cisco SAN-OS Release 3.1(2b) with an SSM running SSI Release 3.1(2m) and with the SANTap feature provisioned. The failure occurs while the DPP is processing an unexpected transfer ready message.
Workaround: None.
•
Symptom: The Java Help search engine in Cisco Fabric Manager and Device Manager does not work correctly in Cisco SAN-OS 3.1(2).
Workaround: None.
•
Symptom: If you disable error or discard messages in Performance Manager via the server.properties file, you may see the following error in the FMServer.log file:

Workaround: None.
•
Symptom: When you enter the show fcip tape-session command, the switch displays the outputs of the first ten sessions, but additional session outputs are needed.
Workaround: None.
•
Symptom: If you attempt to examine the logging information of an FCIP tunnel that has write acceleration enabled, you might notice that some of the logs do not contain the correct debugging information. The logging information can be used to debug possible error conditions in an FCIP tunnel.
Workaround: None. This issue does not affect functionality. The trace logs are used to collect only debugging information.
•
Symptom: Following an upgrade, a device might be incorrectly imported to a non-native VSAN.
Workaround: Shut down and then re-enable the host's port on the switch before importing the device.
•
Symptom: For passwords authenticated by an AAA server, the MDS switch should inform the user when their password is about to expire.
Workaround: This is an enhancement. It is available only for CLI logins. Fabric Manager and Device currently do not support this feature.
