Configuration and Image Commands
The primary MSM also synchronizes its configurations with the backup MSM which allows the backup
to take over the management functions of the primary.
NOTE
If you download an image to the backup MSM, the image passes through the primary MSM before the image is
downloaded to the backup MSM.
1 View your selected and booted partition using the following command:
show switch
Output from this command includes the selected and booted images and if they are in the primary
or the secondary partition. The selected image partition indicates which image is used at the next
reboot. The booted image partition indicates the image used at the last reboot.
2 Select the partition to download the image to and download and install the new ExtremeWare XOS
software on the backup MSM using the following command:
download image [[<hostname> | <ipaddress>] <filename> {{vr} <vrname>} | memorycard
<filename>] {<partition>} {msm <slotid>}
NOTE
If the backup MSM is installed in slot B, specify msm B. If the backup MSM is installed in slot A, specify msm
A.
Before the download begins, the switch prompts you to install the image immediately after the
download is finished. If you install the image immediately after download, the switch reboots.
If you download and install the software image on the active partition, you need to reboot the
●
switch. 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
y
If you download and install the software image on the non-active partition, you do not need to
●
reboot the switch.
If you install the image at a later time, use the following command to install the software:
●
install image <fname> {<partition>} {msm <slotid>} {reboot}
3 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.
4 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.
