Maintaining Supervisor Modules

This section includes general information about replacing and using supervisor modules effectively.

If the standby supervisor module boot variable images are not the same version as those running on the

active supervisor module, the software forces the standby supervisor module to run the same version as

the active supervisor module.

If you specifically set the boot variables of the standby supervisor module to a different version and

reboot the standby supervisor module, the standby supervisor module will only load the specified boot

variable if the same version is also running on the active supervisor module. At this point, the standby

supervisor module is not running the images set in the boot variables.

When updating software images on the standby supervisor module, verify that there is enough space

available for the image using the dir bootflash://sup-standby/ command. It is a good practice to remove

older versions of Cisco MDS SAN-OS images and kickstart images. For information about displaying

file systems and removing files, see the

If a standby supervisor module fails to boot, the active supervisor module detects that condition and

generates a Call Home event and a system message and reboots the standby supervisor module

approximately 3 to 6 minutes after the standby supervisor module moves to the

The following system message is issued:

%DAEMON-2-SYSTEM_MSG:Standby supervisor failed to boot up.

When you replace any module (supervisor, switching, or services module), you must ensure that the new

module is running the same software version as the rest of the switch.

Refer to Cisco MDS 9000 Family SAN Volume Controller Configuration Guide for configuration details

on replacing the caching services module (CSM).

When a spare standby supervisor module is inserted, it uses the same image as the active supervisor

module. The Cisco SAN-OS software image is not automatically copied to the standby flash device.
