Chapter 8 Upgrading CSM Software

Upgrading the Switch Software

This upgrade requires a dual-supervisor MDS 9500 director. This procedure only upgrades the switch
software—not the SVC software that is running on the nodes in the cluster.
Use the install all command to do switch software upgrade irrespective of the modules present in the
switch.

Performing the Switch Upgrade

To perform an automated software upgrade on any switch, follow these steps:
Log into the switch through the console, Telnet, or SSH port of the active supervisor.
Step 1
Perform the upgrade by issuing the install all command.
Step 2
switch# install all system bootflash:system-image kickstart bootflash:kickstart-image
At this point, the following events happen:
•
•
•
Select y if you choose to continue or n if you choose to cancel the upgrade.
Step 3
•
•
Exit the switch console and open a new terminal session to view the upgraded supervisor module using
Step 4
the show module command.

Sample Switch Upgrade

switch# install all system
scp://usery@171.69.16.22/auto/vwsvkd/usery/m9500-sf1ek9-mzg.1.3.x.bin
For scp://usery@171.69.16.22, please enter password:

The installer checks if the new switch system software is compatible with the SVC software for both
nodes in a CSM and for all CSMs in the switch.
You will receive the following descriptive information on the intended changes to your system:
a compatibility assessment for each module in the switch
–
a upgrade assessment
–
– a module version comparison
See the "Sample Switch Upgrade" section on page 8-7
Once the effects of the command are presented, you can choose to continue or cancel when you see
this question (the default is no):
Do you want to continue y/n? [n] :y
y = each CSM module is upgraded—one at a time, with a gap of 30 minutes between each to ensure
that only one node in the I/O group is down at any time. This allows time for the host multipathing
software to rediscover paths to the modules containing nodes that were upgraded first.
If incompatibility warnings exist, the incompatible CSM nodes are shut down after the upgrade.
–
If incompatibilities do not exist, the CSM nodes are upgraded.
–
n = the installation process is aborted.
