Managing SSMs and Supervisor Modules
This section describes the considerations for replacing SSMs and supervisor modules and for upgrading
and downgrading Cisco MDS NX-OS and SAN-OS releases.

Configuring SSM Global Upgrade Delay

When there are multiple SSM/MSMs in the same chassis, you can set the amount of time to delay
between the SSM/MSMs in a rolling SSI upgrade.
To set the global SSM upgrade delay time, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# ssm upgrade delay
{1-600-in-seconds}
switch(config)#
switch(config)# no ssm upgrade delay
switch(config)#
To set the global SSM upgrade delay time, follow these steps.
From the Fabric Manager window, select Physical Attributes > Intelligent Features > SSM Globals
Step 1
tab. The SSM Globals tab is displayed with the list of switches.
In the UpgradeDelay column, enter a value between 0 and 600 for each switch.
Step 2

Considerations for Replacing SSMs and Supervisor Modules

If you replace an SSM or supervisor module, you should consider the following:

If you replace an SSM with another SSM and the boot image is on bootflash:, respectively, you can
leave the boot image installed on the active supervisor.
If you replace an SSM with another SSM and the SSI boot image is on the modflash:, the SSM might
not initialize. See the "Recovering an SSM After Replacing Corrupted CompactFlash Memory"
section on page 12-29.
If you replace an SSM with any other module, you can leave the boot image installed on the active
supervisor or remove it. The active supervisor module detects the module type and boots the module
appropriately.
If you replace a supervisor module in a switch with active and standby supervisors, no action is
required because the boot image is automatically synchronized to the new supervisor module.
If you replace a supervisor module in a switch with no standby supervisor, you need to reimplement
the configuration on the new supervisor.
Purpose
Enters configuration mode.
Delays the SSI upgrade on the second and the subsequent
SSM/MSMs by the specified time in seconds.
Clears the SSI upgrade delay timer.
