Standby Supervisor Boot Alert
If a standby supervisor module fails to boot, the active supervisor module detects that conditions and
generates a Call Home event and a SYSLOG message and reboots the standby supervisor module
approximately 3 to 6 minutes after the standby supervisor module moves to the loader> prompt.
The following SYSLOG error message is issued:
%DAEMON-2-SYSTEM_MSG:Standby supervisor failed to boot up.
This error message is also generated if one of the following situations apply:

Replacing Modules
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 the 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 SAN-OS software image is not copied to the standby flash until you issue an install all
command. Refer to the Cisco MDS 9000 Family Configuration Guide for more information.
Recovering a Corrupted Bootflash
All switch configurations reside in the internal bootflash. If you have a corrupted internal bootflash, you
could potentially lose your configuration. Be sure to save and back up your configuration files
periodically. Refer to the Cisco MDS 9000 Family Configuration Guide for information on recovering a
corrupted bootflash.
