ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Configuration and Image Commands
3 Verify that the backup MSM comes up correctly and that the MSMs are synchronized using the
following command:
show switch
The current state indicates which MSM is the primary (displayed as MASTER), which MSM is the
backup (displayed as BACKUP), and if the backup MSM is synchronized with the primary MSM
(displayed as In Sync).
4 Initiate failover from the primary MSM to the backup MSM using the following command:
run msm-failover
When you failover from the primary MSM to the backup MSM, the backup becomes the new
primary, runs the newly downloaded software, and provides all of the switch management
functions.
If you have a BlackDiamond 8800 series switch and the new ExtremeWare XOS image supports
hitless upgrade but is not compatible with the current running I/O module image (the I/O version
numbers do not match), you cannot perform a hitless upgrade.
The switch displays a warning message similar to the following:
WARNING:
If you continue with the MSM failover, all I/O modules will be reset.
Are you sure you want to failover? (y/n)
You can either continue the upgrade or cancel the action. If you continue the upgrade, the primary
MSM downloads the new image to the I/O module and reboots.
5 Verify that the backup MSM comes up correctly and that the MSMs are synchronized using the
following command:
show switch
The current state indicates which MSM is the primary (displayed as MASTER), which MSM is the
backup (displayed as BACKUP), and if the backup MSM is synchronized with the primary MSM
(displayed as In Sync).
6 Select the partition to download the image to and download and install the new ExtremeWare XOS
software on the new backup MSM (this was the original primary MSM) using the following
command:
download image [<hostname> | <ipaddress>] <filename> {vr <vrname>} msm <slotid>
NOTE
If the new backup MSM is installed in slot A, specify msm A. If the new backup MSM is installed in slot B,
specify msm B.
Before the download begins, the switch asks if you want to install the image immediately after the
download is finished. If you download and install the image immediately to the active partition, the
switch automatically reboots the MSM.
If you download and install the software image on the active partition, the switch automatically
●
reboots the MSM after the image is installed. The following message appears when downloading
and installing on the active partition:
Image will be installed to the active partition, a reboot required. Do you
want to continue? (y or n)
Enter
