This chapter describes the procedures for installing system software V5.1 FSR00 on systems currently running V4.2 FSR00 or greater, or V5.0 FSR00 or greater, of the system software.
 |
Note If you are installing system software in a redundant system, it is recommended that you use the Live Upgrade procedure described in this chapter. Using Live Upgrade eliminates the need to power down your system, thereby preserving call flow. If you are installing system software in a non-redundant system, you must use the installation procedures described in "Install the System Software." |
|
Note To upgrade current system software to version 5.1, version 4.2 or greater is required. If you are currently running a system software version less than V4.2, you must perform a two-stage upgrade: upgrade from V3.3.xx to V4.2, then from V4.2 to V5.1. A database conversion is required for each upgrade. Refer to Generic V4.2 Release Notes to upgrade to V4.2. Contact TAC if you are running a version of the system software prior to V3.3.3. |
Refer to "Overview of the Installation Procedure" section before you begin the Live Upgrade procedures.
Use the Live Upgrade option to update software on a redundant VCO/4K system without loss of calls, and with a minimum reduction in capacity. The procedure consists of:
|
Note System software version 4.2.0.24 or higher is required to perform a live upgrade. |
You can abort the process at any time and restore the prior version until the time when the active controller is running the new release of software. To revert to the prior release of software after the active controller is running the new software, you must perform a non-live (manual) installation of the prior release.
|
Note Live upgrade does not support SS7 upgrade. Following a live upgrade to the system software, systems that are not configured to reset upon a system controller reset require manual reset of the Sparc. The SS7 system must also be configured to auto-start the SS7 software. |
 |
Caution The MIB software is not backward compatible. If you are using SNMP, and you upgrade to this software release, you must recompile the MIB. |
It is important that you note the following guidelines and restrictions to ensure a successful live upgrade.
Note the following when performing a live upgrade:
|
Note Hardware and/or firmware updates require on-site personnel. In this case, the live upgrade cannot be done remotely. |
|
Note You must manually specify the day, month, and year of the log file before you display or print the file. See DDTs issue CSCdp46309 for further information. |
|
Note If a printer is connected to the system while the live upgrade is in progress, both the regular and live upgrade log files are printed. Live upgrade log file messages appear indented with respect to the regular log file messages. |
Live Upgrade is available for system software V4.2 and higher; however, some special procedures are required for certain releases. Refer to the following two sections for valuable workaround procedures.
Complete the steps below to use Live Upgrade if you are using system software V4.2 and higher.
|
Caution If you are using system software from V5.0.0.25 through V5.1.0.26, you must complete the steps below, and the steps in the following section, Live Upgrade Procedures from V5.0.0.25 through V5.1.0.26, so that you do not lose all calls. |
|
Caution Do not access the Software/Firmware Configuration screen at any time during Live Upgrade procedures. Failure to follow this instruction results in Live Upgrade failure. Proceed to Step 1 below; do not deviate from these procedures. |
Step 1 Boot the standby side of the switch.
Step 2 Wait for file synchronization and perform a switchover.
Step 3 Boot the new standby side; wait for file synchronization.
Step 4 Go to the next section, Live Upgrade Procedures from V5.0.0.25 through V5.1.0.26, to complete Live Upgrade.
Complete the following steps to use Live Upgrade from system software V5.0.0.25 through V5.1.0.26. This procedure prevents DSP failure on switchover.
|
Caution Follow this workaround procedure when using Live Upgrade from V5.0.0.25 through V5.1.0.26. Failure to do so will result in the loss of all calls that require SPC resources. Use this procedure to minimize the volume of lost calls, limiting them to those calls that are active on the SPC and that are taken out of service in order to re-flash. |
Step 1 Load the new SPC.DWN on the active side of the system.
Step 2 Take one SPC out of service (OOS).
Step 3 Place the same SPC in the active state.
Step 4 Wait for the download to complete and all DSPs become active on the SPC.
Step 5 Repeat Step 2 through Step 4 for all other SPCs, one at a time.
Step 6 Go to the next section, Live Upgrade Access, to complete Live Upgrade.
All other system software versions are compatible with the Live Upgrade procedures described in the remainder of this chapter.
To upgrade a system via live upgrade, you need to perform some or all of the following four basic tasks (tasks 1 and 3 are mandatory).
Step 1 Follow the live upgrade procedure to upgrade the software on both sides of the system.
Step 2 Update the CPU, and/or the NBC-3, and/or DTG/DTG-2, if needed.
Step 3 Switch over to the new software release.
Step 4 Update certain network and/or service circuit cards, if needed.
Step 5 To access the Live Upgrade Control Menu screen (see Figure 2-1) from the Maintenance menu, press L.
The cursor is located in the Enter Selection field.
Screen selections are limited to the appropriate letter for the current step as indicated as part of the Enter Selection prompt. In Figure 2-1, valid selections are A, H, and K.
The system lets you know that a live upgrade is in progress by displaying UAC or USB at the bottom of the screen; UAC indicates Upgrade Active mode and USB indicates Upgrade Standby mode. As shown in Figure 2-1, side A is in standby mode and side B is active.
The upgrade process is illustrated in Figure 2-2. Table 2-1 lists the steps required to perform a live upgrade, as well as which option to select from the Live Upgrade Control Menu, and the actions taking place within the system. A detailed description of the steps begin in "Perform a Live Upgrade" section.
| Screen Selection | Action | |
|---|---|---|
Step 1 | Option A | Prepare for the installation of the new release on active and standby sides. Directories that are needed for the process are automatically created. The current release on each side of the system is backed up. |
Step 2 | Option H | Back up the existing database on the active and standby sides. |
Step 3 | Option B | Install the new software on the active and standby sides. The system installs the necessary files on each controller of the switch. |
Step 4 | Option C | Prepare for the upgrade on the standby side. The system is set up to boot from the new release. Suitability of system to accept the release is checked. |
Step 5 | Option D | Enable/disable/configure optional software (Ethernet, ISDN, NFAS, TeleRouter) on the standby side. |
Step 6 | Option E | Update the system software on the standby side. The system automatically reboots the standby side with the new release and performs a database conversion. The system synchronizes the dynamic information. |
|
| Standby side reboots and NBC downloads. |
Step 7 | Option F | Switch the active side to standby. The alternate side is updated. After this step is complete, you can no longer abort the upgrade. Repeat steps 4 to 6 on the standby controller. |
|
| Wait for file synchronization. |
Step 8 | Option C | Prepare for the upgrade on the new standby side. The system is set up to boot from the new release. Suitability of the system to accept the release is checked. |
Step 9 | Option D | Enable/disable/configure optional software (Ethernet, ISDN, NFAS, TeleRouter) on the new standby side. |
Option E | Update the system software on the new standby side. The system automatically performs a database conversion. The system synchronizes the dynamic information. | |
|
| Wait for file synchronization. If you are running conferences on the VCO/4K during the live upgrade procedure, Cisco recommends that you proceed to Step 13, Option 1. |
Step 11 | Option G | Cut over port and service cards on the active side. The system switches over the port and service cards. |
Step 12 | Option H | Back up the new databases on the active and standby sides. |
Option I | Clean up the active and standby sides. If you are proceeding with this step directly from Step 10 due to running conferences, access the system administration Card Maintenance screen to download the new software to the VCO/4K system cards. |
The following is a detailed explanation of the steps outlined in Table 2-1. Follow these steps to perform a live upgrade on your system. When referring to Option x (where x signifies the option letter from the Live Upgrade Control Menu screen), you are directed to select the appropriate option from the Live Upgrade Control Menu screen. For example, Option A directs you to select the Prepare for Install option.
This step must be performed on both controllers (active and standby side).
To initiate installation of both the active and standby sides, select the Prepare for Install option on the Live Upgrade Control Menu; type A then press Enter.
The installation routine determines if the disk has enough free space to create a new directory structure and store the new files. If a shortage of disk space is detected, you are notified and the upgrade is automatically aborted.
If you do not have enough free space to perform the upgrade and are unsure of the disk maintenance necessary to obtain it, contact Cisco Systems TAC.
The directory structure that is required by the upgrade process is shown in Figure 2-3. The directories created for the upgrade procedure are shown in bold; they are automatically created by the system software when you select the Prepare for Install option. If they already exist, any existing files are removed from the directories. The directories themselves are maintained, and are used during the upgrade process.
The directory and its purpose are:
C:/new/boot | The new executable files and download application files. |
C:/new/dbase | The new, empty database. |
C:/old/boot | The current software release. The current system software is restored from this directory if you select the Abort Upgrade option from the Live Upgrade Control Menu. |
C:/old/dbase | The current database. The current database is restored from this directory if you select the Abort Upgrade options from the Live Upgrade Control Menu. |
|
Note You can abort the upgrade at this time: Select option J from the Live Upgrade Control Menu. |
The first step in the live upgrade process is to back up the existing database. Do this before proceeding to the next step. You must perform this step on both system controllers. Also note that backup of a standby controller is allowed only during live upgrade.
You should back up your current database in case it is necessary to restore the previous system software version from floppy diskette. The backup database option on the Live Upgrade Control Menu is similar to the manual database backup utility.
To back up your existing database, insert a blank diskette and press H. When the Store from C:/ to A:/ YES/NO prompt is displayed; press Y to continue with the database backup process.
|
Note You can abort the upgrade at this time: Select option J from the Live Upgrade Control Menu. |
After the new directories are created and you have performed a database backup, install the new system software and database in the appropriate directories on the internal hard drive of both active and standby system controllers.
Install the new software from floppy diskettes, or from another host with FTP or FTP and PPP, if Ethernet or a modem connection is available and FTP is supported within the system controller software. The files are copied to the subdirectories under the C:/new directory.
Perform Step 3 on both system controllers before proceeding to the next step. After completing Step 3 on both controllers, continue the upgrade process on the standby controller. No further activity is performed on the active controller until you have upgraded the standby controller.
|
Note You can abort the upgrade at this time: Select option J from the Live Upgrade Control Menu. |
When you select the Install New Release option from the Live Upgrade Control Menu, the VCO Installation screen is displayed (see Figure 2-4).
To install from floppy diskettes, type 1, then press Enter. The VCO Floppy Installation screen is displayed (see Figure 2-5).
You are prompted to insert the installation diskettes into the floppy drive so that the files can automatically be transferred into the appropriate directories. Press any key other than Enter or Return to stop the loading of files from the floppy drive.
The floppy diskette number is displayed in the VCO Floppy Installation screen; for example, Insert Generic Floppy 1. When you insert the floppy diskette the volume label is verified. Your response (for example, if you pressed the Enter key to continue) is logged in the upgrade log file along with the files that are being installed. If any files are missing from the floppy, or if there is a mismatch, the upgrade is aborted.
After all software diskettes have been installed, you are prompted to install optional software. (See Figure 2-6.) If no other software is to be installed, select option 2: Installation Complete (see Figure 2-6) and press Enter to exit the installation.
After the system software is installed, you can install optional software package files. (See Figure 2-6.)
To install an optional software package:
After completing the installation of an option, the menu in Figure 2-6 is displayed again. Select Option 1 again to install another software package, or select Option 2: Installation Complete, to terminate the installation.
In a separate step, you must enable and configure the optional software; refer to the "Install from Another Host" section.
If you install the software from a remote computer through FTP via Ethernet, or PPP, you control the process from the FTP client. You are required to select the needed files and copy them to the appropriate subdirectories under the C:/new directory. This option assumes that you know how to FTP files from your host computer to the VCO system.
When the FTP transfer of the new system software to the hard disk is complete, you must indicate that the transfer is complete by selecting Option 2 in the VCO Installation screen. (See Figure 2-4.) The system software then verifies that the transfer is complete. Successful transfer is indicated by the Check for all Files Successful message.
On the standby side of the system, select the Prepare for Live Upgrade option from the Live Upgrade Control Menu. Type C then press Enter. You perform this step later on the other side of the system; refer to the "Step 8: Prepare to Upgrade the Remaining Side" section.
During this step, the system software automatically performs several tasks and verifies that:
|
Note If the configuration is not suitable, information is logged and the upgrade is prohibited. |
You are notified if there are single resources in the system that require updating. Note that updating a single resource causes a loss of capacity for that resource. Refer to Cisco VCO/4K System Messages for live upgrade messages.
When verification of the preceding has been successfully completed, the existing system software and the switch configuration is copied to the C:/old directory. Finally, the system software copies the new boot files from C:/new/boot into the current boot area, C:/boot. During this and later steps, you are locked out from making any configuration changes on the system.
|
Note You can abort the upgrade at this time: Select option J from the Live Upgrade Control Menu. |
This step is optional. If you do not have optional software, skip this step.
|
Note Users of system software version 5.1(3) and higher must skip this step; proceed to Step 6: Update the System Software. Optional software products for users of V5.1(3) and higher are enabled upon installation. |
To initiate step 5, perform the following steps.
Step 1 Select the Enable/Disable/Configure Optional S/W option from the Live Upgrade Control Menu.
Step 2 Type D then press Enter.
The screen shown in Figure 2-7 is displayed. Perform this step on the standby side of the system.
|
Note The only the optional software packages that have been installed are shown in the Enable/Disable/Configure Optional S/W screen. |
The Enable/Disable/Configure Optional Software procedure consists of two parts; 1) enable the options, and 2) configure the options.
You can enable or disable software depending on its current state. For instance, note in Figure 2-7 that the only software package enabled is TeleRouter, since the option for TeleRouter is to Disable. All other options are to Enable, thereby indicating that the other software packages (Ethernet, ISDN, NFAS, NI-2) are currently disabled.
If you select the Enable Ethernet option, you are prompted to set the parameters. The Ethernet configuration process is the same as the manual Ethernet configuration process, that is, installing Ethernet using the Ethernet Install diskette.
|
Note You can abort the upgrade at this time: Select option J from the Live Upgrade Control Menu. |
Perform this step on the standby side of the switch. This step results in an update of the system software.
|
Note The system is non-redundant from the time you start the update of one side (step 6) until the time that new release is running on both sides of the system. Once both sides are running the new release of software, the system returns to a redundant mode of operation. |
Any hardware or firmware upgrades required on the standby NBC-3, the DTG-2 card on the standby NBC-3, and/or the standby CPU should be done before initiating step 6. Refer to the following subsections for information on upgrading the firmware and/or hardware before proceeding.
To initiate step 6, select the Update Generic option on the Live Upgrade Control Menu; type E then press Enter.
When the Update Generic option is selected:
1. The standby side is rebooted.
2. The new system software performs a database conversion (if needed).
3. A login screen is displayed on the console.
To upgrade the CPU, select option E, Update Generic, and press Enter. Once the CPU reboots, you may remove the CPU card for upgrading.
If you are replacing a 25MHz/8MB CPU with a 33MHz/16MB CPU, refer to the Cisco VCO/4K Card Technical Descriptions for a step-by-step procedure.
|
Note A CPU card which is housed in a combined controller carrier may be removed from the card cage while under power. If the CPU is not housed in a combined controller carrier, you must first remove the power to the standby CPU. Refer to the Cisco VCO/4K Card Technical Descriptions for removal and replacement procedures. |
After upgrading the hardware/firmware, insert the CPU card into the system and restore power if it had been previously powered off.
If the hardware or firmware of the NBC-3 card needs to be replaced, it should be done at this time. An NBC-3 card that is in standby mode can be removed while the system is running.
Note that when the NBC-3 card is removed, a DTG-2 card mounted on that NBC-3 is consequently also removed and updated (see the following subsection). If the DTG-2 card is the only tone generator in the switch, the system will experience a loss of tone generation resources while the NBC-3 and/or DTG-2 is upgraded. Refer to the Cisco VCO/4K Card Technical Descriptions for removal and replacement procedures.
To upgrade the NBC-3, select option E, then press Enter. Once the CPU reboot process starts, the NBC-3 may be removed and upgraded. After restoring the NBC-3 card, reset the standby CPU via the Alarm Arbiter Card.
|
Note If your system has a DTG card, the card does not get updated at this time. |
If the hardware or firmware of the DTG-2 card needs to be replaced, you should do it at this time. You must take the DTG-2 out of service (OOS) when its firmware or hardware is updated.
Upgrade the DTG-2 mounted on the standby NBC-3, even if it is the active tone card. If your system has redundant tone cards, assure that the DTG-2 card on the standby NBC-3 is in standby mode. If the system does not have redundant DTG-2 cards, note that the system will experience a loss of tone generation resources while the DTG-2 is upgraded.
To upgrade the DTG-2, select option E, then press Enter.
When you upgrade your system software via live upgrade, the system performs an automatic database conversion as part of the upgrade.
When the new system software is running, a database conversion is automatically performed by the software. The converted files are updated in the C:/dbase directory and loaded into memory as the static portion of the new database. Any new tables needed for the upgrade are obtained from the C:/new/dbase directory. Note that some upgrades may not require a database conversion.
|
Note You can abort the upgrade at this time: Select option J from the Live Upgrade Control Menu. |
|
Caution Before you begin this step, make certain that the file synchronization (static database and dynamic state information) has completed. A message is displayed on your screen indicating that the synchronization is complete. |
In step 7, place the active side (controller) in standby mode. When this is done, the previously active side, running the old system software, becomes available to upgrade. In addition, the side which was in standby mode will become active and be running the new software.
To initiate this step, on the active side of the system, choose the Switchover to Standby option from the Live Upgrade Control Menu; type F then press Enter.
|
Note Make certain your console is on the active side of the switch when performing the switchover. |
|
Caution When this step is complete, the upgrade can no longer be aborted. If restoring the old software release is required, you must perform a traditional reinstallation of the original software. |
Once the switchover has taken place, i.e., the reboot and NBC download are complete, your console should be on the standby controller's side (the controller that needs to be updated).
This is a repeat of the steps already performed on the other side, described in Step 4: Prepare for the Upgrade. This now becomes the new standby side of the system. Select the Prepare for Live Upgrade option from the Live Upgrade Control Menu. Type C then press Enter.
During this step, the system software automatically performs several tasks and verifies that:
C:/new directory on the hard drive and that all needed files are available for the upgrade. |
Note If the configuration is not suitable, information is logged and the upgrade is prohibited. |
You are notified if there are single resources in the system that require updating. Note that updating a single resource causes a loss of capacity for that resource. Refer to Cisco VCO/4K System Messages for live upgrade messages.
When verification has been successfully completed, the existing system software and the switch configuration is copied to the C:/old directory. Finally, the system software copies the new boot files from C:/new/boot into the current boot area, C:/boot. During this and later steps, you are locked out from making any configuration changes on the system.
|
Note The upgrade can no longer be aborted. |
Perform this step on the new standby side of the switch. Skip this step if you do not have optional software.
To initiate step 9, select the Enable/Disable/Configure Optional S/W option from the Live Upgrade Control Menu; type D then press Enter. The screen shown in Figure 2-7 is displayed.
|
Note The only the optional software packages that have been installed are shown in the Enable/Disable/Configure Optional S/W screen. |
This step consists of two parts:
1. Enable the options.
2. Configure the options.
You can enable or disable software depending on its current state. For instance, note in Figure 2-7 that the only software package enabled is TeleRouter, since the option for TeleRouter is disabled. All other options are to enabled, thereby indicating that the other software packages (Ethernet, ISDN, NFAS, NI-2) are currently disabled.
If you select the Enable Ethernet option, you are prompted to set the parameters. The Ethernet configuration process is the same as the manual Ethernet configuration process, i.e., installing Ethernet using the Ethernet Install diskette.
|
Note The upgrade can no longer be aborted. |
Perform this step on the new standby side of the switch. This step results in an update of the system software.
|
Note The system is non-redundant from the time you start the update of one side (step 6) until the time that new release is running on both sides of the system. Once both sides are running the new release of software, the system returns to a redundant mode of operation. |
Any hardware or firmware upgrades required on the standby NBC-3, the DTG-2 card on the standby NBC-3, and/or the standby CPU should be done before initiating step 10. Refer to the following subsections for information on upgrading the firmware and/or hardware before proceeding.
To initiate step 10, select the Update Generic option on the Live Upgrade Control Menu; type E then press Enter.
When the Update Generic option is selected:
1. The standby side is rebooted.
2. The new system software performs a database conversion (if needed).
3. A login screen is displayed on the console.
To upgrade the CPU, select option E, Update Generic, and press Enter. Once the CPU reboots, you may remove the CPU card for upgrading.
|
Note A CPU card which is housed in a combined controller carrier may be removed from the card cage while under power. If the CPU is not housed in a combined controller carrier, you must first remove the power to the standby CPU. Refer to the Cisco VCO/4K Card Technical Descriptions for removal and replacement procedures. |
After upgrading the hardware/firmware, insert the CPU card into the system and restore power if it had been previously powered off.
If the hardware or firmware of the NBC-3 card needs to be replaced, it should be done at this time. An NBC-3 card that is in standby mode can be removed while the system is running.
Note that when the NBC-3 card is removed, a DTG-2 card mounted on that NBC-3 is consequently also removed and updated (see the following subsection). If the DTG-2 card is the only tone generator in the switch, the system will experience a loss of tone generation resources while the NBC-3 and/or DTG-2 is upgraded. Refer to the Cisco VCO/4K Card Technical Descriptions for removal and replacement procedures.
To upgrade the NBC-3, select option E, then press Enter. Once the CPU reboot process starts, the NBC-3 may be removed and upgraded. After restoring the NBC-3 card, reset the standby CPU via the Alarm Arbiter Card.
|
Note If your system has a DTG card, the card does not get updated at this time. |
If the hardware or firmware of the DTG-2 card needs to be replaced, you should do it at this time. You must take the DTG-2 out of service (OOS) when its firmware or hardware is updated.
Upgrade the DTG-2 mounted on the standby NBC-3, even if it is the active tone card. If your system has redundant tone cards, assure that the DTG-2 card on the standby NBC-3 is in standby mode. If the system does not have redundant DTG-2 cards, note that the system will experience a loss of tone generation resources while the DTG-2 is upgraded.
To upgrade the DTG-2, select option E, then press Enter.
When you upgrade your system software via live upgrade, the system performs an automatic database conversion as part of the upgrade.
When the new system software is running, a database conversion is automatically performed by the software. The converted files are updated in the C:/dbase directory and loaded into memory as the static portion of the new database. Any new tables needed for the upgrade are obtained from the C:/new/dbase directory. Note that some upgrades may not require a database conversion.
For redundant systems, after you have installed the software on both sides and rebooted the system, you must verify that file synchronization has occurred. Check the messages in the log file and verify that the following messages appear:
RED32:ACT FILE SYNC COMPLETED (from the active side)
RED20:SBY FILE SYNC COMPLETED (from the standby side)
When you have verified file synchronization, the installation of system software is complete. Proceed to the "Install the MIB Software" section, to install the MIB software if you have a Network Management System.
|
Note You cannot abort the upgrade at this time. If you are running conferences on the VCO/4K during the live upgrade procedure, Cisco recommends that you proceed to "Step 13: Cleanup" section on page 2-22. |
Once the new release is running on both sides of the system and the file synchronization is complete, cut over the port and service cards that need to be upgraded, from the active side of the system.
To initiate step 11, on the active side of the system, select the Cutover Port and Service Cards option from the Live Upgrade Control Menu; type G then press Enter. When you select the Cutover Port and Service Cards option, the Card Cut-Over screen is displayed. (See Figure 2-8.) This screen lists the cards needing an upgrade, and the type of upgrade (hardware, firmware, or software) that is needed. The fields and user options are described on the following pages.
From the Card Cut-Over screen, you can control the card cutover by choosing the ordering and timing for the upgrade of the cards. You can select to upgrade a single card, or several cards at a time; this depends on the call handling capacity that is to be maintained on the system. Take cards out of service and, if needed, upgrade the firmware or hardware then place the card back in service. When placed back in service, the new application is downloaded onto the card (if applicable) when it is placed back in service.
You do not have to wait until a card is completely OOS before starting the cutover process on another card. The OOS and Activate options operate on a single card, not a group of cards.
If you try to take the last active card of a resource type (the only card or the last active card of a group) out of service, the system notifies you and requests confirmation prior to performing the request. Refer to Cisco VCO/4K System Messages for a list of prompts, warnings, and error messages.
The Card Cut-Over screen can display up to 14 cards. There can be up to 11 screens, which you can navigate by pressing the Prev Screen key if the previous screen is desired, and the Next Screen key to display the next screen. Use the Exit, Prev Menu, or Main Menu keys to exit the Card Cut-Over screen without making any changes. No changes are made unless you press the Enter key.
The fields on the Card Cut-Over Screen are display-only.
RLSI—Contains the physical location of the card; rack, level, slot and interface that needs upgrading.
Card Type—Indicates the type of card in the location indicated in the corresponding column.
UPG—(Upgrade) Contains information on the type of upgrade needed on the corresponding card. The UPG indicators are:
FIRM VERS—Displays the current firmware version.
D/L VERS—Displays the current download version. If the card does not support a download, the field contains four dashes.
|
Note The version number (FIRM VERS and D/L VERS) information is not available when the card is out of service (O). |
S—Indicates the status of the card, as noted below.
The ACTIVATE, GRACEFUL-OOS, OR FORCE-OOS (A, G, F): field is a data entry field. The options for this field are explained below.
A—Activate. Type A to place the card back in service. This causes an application download upgrade on the card, if appropriate. The system software also verifies that the version number for the firmware is compatible with the application download for the card. If not compatible, you are notified and the activation is prohibited.
Once the card is active again, it is removed from the list in the Card Cut-Over screen, and information is written to the log file to indicate that the card has been upgraded. This information is sent to the standby side via the update channel so that both sides have current information about the status of the cards.
G—Graceful-OOS. Type G to take all idle ports out of service (OOS). The system software waits for active ports to become idle before taking them out of service. Once all ports are idle, the card state is set to OOS. Until the card's status is O, indicating that the card is out of service, the card is still involved in active call processing. This command may take some time to complete, depending upon the duration of the active calls using the card.
F—Force-OOS. Type F for the system software to tear down any active calls and place the card out of service (OOS). If you select this option, you must press the Enter key a second time to confirm that this is what you want to do.
You can upgrade a card once the card state is OOS. You can remove cards which require firmware and/or hardware upgrades from the switch and update them after placing them in an out-of-service state. You can upgrade cards which require a software upgrade by simply activating the card.
When both sides of the system are running the new software release, you can change the configuration of the system. This may be needed to modify the setup of cards to take advantage of new features and capabilities. It is strongly recommended however, that non-upgrade related changes not be made until the upgrade process is complete. This helps isolate any potential problems.
|
Note At this point, you cannot abort the operation. |
This step involves backing up the new database. This is done in the event that there was a database conversion resulting in a changed format.
To back up the new database, from the Live Upgrade Control Menu, type H then press Enter. This option is the same as the Database Store option on the Disk Utilities menu. Refer to the Cisco VCO/4K System Administrator's Guide for detailed information.
You can also use the Copy Files option on the Disk Utilities menu, or FTP operations from a remote system, to store the database in an alternate location.
To initiate the cleanup, from the Live Upgrade Control Menu, type I then press Enter.
|
Note This step is not permitted until both sides are running the new software release, and cleanup should not be performed until the card cutover has been completed. |
