Upgrading MaXum460 Chassis CMM Firmware

You can upgrade or downgrade a MaXum460 Chassis CMM firmware version. In a Dual Chassis configuration, you upgrade the CMMs on the Standby Chassis first. You then fail over the currently Active Chassis and upgrade it. After the upgrade or downgrade, all CMMs in both Chassis must have the same firmware version.

Note: At some stages during this procedure, the Chassis will not have a functional CMM. At these times, hardware monitoring data is not collected and the Chassis fans rotate at maximum speed.

To Upgrade/Downgrade CMM Firmware on a MaXum460 Chassis:

1. Set the MaXum460 Chassis to the Administrative Down state:

   > asg chassis_admin –c <Chassis_id> down

2. Connect to an SGM with SSH or a serial console.
3. Download the applicable firmware version to an SGM.
4. Copy and extract the file to the SGM (that contains the firmware file) to: /var/log
5. Copy the firmware files from the SGM to the CMM in the/tmp/ directory
6. Run:

   # scp sentry.shmm700.* admin@198.51.100.33:/tmp/

   The password is: admin

7. Remove all CMMs from the Chassis.
8. Reinstall one CMM into the Chassis.
9. Open a console connection to the serial port on the CMM front panel.
   (Use the Default parameters: 9600,8,N,1)
10. Run these commands:

    # cd /tmp
# clia terminate
# setenv custcnf C00013
# setenv rc2 /etc/rc.0000-14
# rupgrade --erase-all --base file:///tmp/sentry.shmm700. -k kernel -r rfs -a app

11. Run the firmware installation executable:
    # install.sh

    Note: If the screen becomes unreadable during the upgrade procedure, change the console screen baud rate.

12. When prompted, select the applicable Chassis parameters:
    See sk91980 – "Chassis ID validation" for more information about the PSU type.

    Note: The screens that show can be slightly different.

13. At the Press ENTER to reboot, ^C to abort prompt, press Enter to reboot the shelf manager and complete the upgrade.
14. If the Chassis ID is "2", change the Chassis ID setting:

    # sed -i 's/CHASSID="1"/CHASSID="2"/g' /etc/shmm.cfg

    # reboot

15. If you changed the Chassis ID, reboot all SGMs:

    # g_reboot -b Chassis <Chassis_id>

16. Login via SSH to one of the SGMs in the Down Chassis and run:

    > asg_version -i

17. If you have a second CMM, install it into the Chassis and do steps 8-15 again on the other CMM.
18. Make sure that the Active and Standby CMM both have the same firmware version.
    1. Login via SSH to one of the SGMs.
    2. Run:

       > asg_version -i

19. Change the Chassis back to UP:

    > asg chassis_admin -c <Chassis_id>
