Software Release 2.3(1.1) is an update release based on Software Release 2.3(1). Software Release 2.3(1.1) addresses the following special consideration:
The NP POST is incorrectly updating a temperature sensor warning of EEPROM location.
There are no new features and enhancements for Software Release 2.3(1.1).
The Network Processor POST is incorrectly updating a temperature sensor warning EEPROM location. A NP flash image (which contains a POST executable) must be modified to eliminate this update.
This section provides information about upgrading the LightStream 2020 multiservice ATM switch to Software Release 2.3(1.1) of the LightStream 2020 software.
The software upgrade requirements for installing Software Release 2.3(1.1) are as follows:
Below is a list of the LS2020 Software Release 2.3(1.1) node software distribution diskettes.
| LS2020 Release 2.3(1.1) Distribution Diskette | Version Listed on Diskette Label |
|---|---|
| Upgrade Diskette 1 | 2.3(1.1) |
With this procedure, you copy the new software to a local LS2020 node from the distribution disk set. This local node is referred to as the distribution node. To perform this procedure, use a terminal connected to the console port of the distribution node. Only the person doing the installation should be logged on to the system.
The following tasks are necessary for an upgrade to the distribution node (or any local node) to Software Release 2.3(1.1) node software:
To perform these tasks, use a terminal connected to the console port of the distribution node. The system should be running with no one else logged on the system.
Step 1 Enter '. (backquote plus dot, that is, left single quote plus period).
Step 2 At the TCS HUB prompt, use the connect command to connect to the NP in slot 1:
You may need to press Return a second time after typing the connect command in order to get a prompt from the NP.
A prompt should appear asking for a user login name:
Step 3 Log in as root. The bash prompt appears (with # indicating a root login):
root
password:Step 4 On a system with redundant NPs, verify that you are connected to the primary NP (the active NP), as follows:
bash# cli
| Are you connected to the primary or backup NP? | If the two entries identify the same NP number, you are connected to the primary NP (the active NP). Since you connected to slot 1 in Step 1, above, the following is true:
primary = 1 Make a note of this. Use the value 1 where you see the parameter name "primary" in later procedures. If the two entries do not identify the same NP number, you are connected to the backup NP. Since you connected to slot 1 in Step 1 above, the following is true: primary = 2 Make a note of this. Use the value 2 where you see the parameter name "primary" in Step 5, below, and in other procedures. |
Step 5 If you are connected to the backup NP, disconnect from it and connect to the primary NP (the active NP):
TCS HUB<<A>> connect primary
Step 6 Determine which floppy disk drive is appropriate to use for the upgrade. NP slot 1 is connected to the bottom disk drive, and NP slot 2 is connected to the top disk drive.
The boot disk is not used in this upgrade procedure. You will run the swinstall utility once for each diskette set in the following order:
| If you are currently running version... | Install the floppy diskette sets in this order |
|---|---|
| 2.03 through 2.0(9.2) | Obtain the 2.3(1) Release Notes and floppy diskettes; install the diskettes in the recommended order. |
| 2.3(1) | 2.3(1.1) Update diskette |
Step 7 Enter the swinstall command at the bash prompt:
swinstall
When the program prompts you for a diskette, insert the first diskette (of the diskette set that you are currently installing) into the appropriate drive and press Return. Repeat as the program prompts you for more diskettes in the current set.
Step 8 Repeat Step 7 for each diskette set, following the order given under Step 6.
With this procedure you distribute new software from the distribution node to other LS2020 nodes. Carry out this procedure for all remote nodes before going to Procedure 3, Change the Running Software Version.
The following connectivity requirements apply
| Distribution Node | Remote Node |
|---|---|
|
|
Perform the following steps for each node in your LightStream 2020 network:
Step 1 Verify remote command execution.
Step 2 Distribute Release 2.3(1.1) to the remote node.
Verify that it is possible to execute commands on the remote node from the distribution node:
Step 1 On the distribution node, execute the following command:
remote-node hostname
Enter the name of the remote node in place of remote-node.
If the command succeeds, it prints the name of remote-node. Continue to Step 2 .
If this is the first time you have upgraded, this step is likely to fail. If the command fails, it prints one of the following messages:
hostname: unknown host
hostname: Connection timed out
Permission denied.
Step 2 Copy Release 2.3(1.1) files to remote-node. In a window running a login on distribution-node, execute the following command:
Enter the name of the remote node in place of remote-node.
The swremoteinstall process checks disk space and copies Release 2.3(1) to remote-node. It should take 5 to 10 minutes, depending upon bandwidth between the nodes.
There are no changes to this procedure. For more information, see Software Release 2.3(1) Software Upgrade Procedures.
There are no changes to this section. For more information, see Software Release 2.3(1) Special Considerations.
This section lists the resolved problems for this and previous releases since 2.3(1).
The resolved problems listed below have been fixed in Release 2.3(1.1):
LSCle05527 | NP POST incorrectly adjusts TEMP2 WARN value (0x86 should be 0x93) |
In Software Release 2.3(1.1), one checksum value has changed for the network processor.
Every time you install a card in a slot of the system, you must verify that it has the correct Flash memory checksum, and upgrade Flash if necessary. The procedure for doing this is given in the LightStream 2020 Hardware Reference and Troubleshooting Guide. Use the bash command sysver -a | more to display Flash checksums. The checksums for this new release are listed below.
If the Flash checksum is 0xE82A for a Release 2 switch card, or 0x50CA for a Release 1 switch card, then the specified switch card already has the latest Flash image.
The following diagnostic versions are used in this release.
diag_clc1.aout version 2.110
diag_ls1.aout version 0.721
diag_ms1.aout version 1.495
diag_np1.aout version 1.575
diag_plc1.aout version 2.005
sys_np1.aout version 1.460
