Standby Supervisor Module Bootflash Memory

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 NX-OS images and kickstart images.

Standby Supervisor Module Boot Alert

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 loader> prompt.
The following system 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 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
Note
module. The Cisco NX-OS software image is not automatically copied to the standby flash device.

You remain at the loader> prompt for an extended period of time.
You do not set the boot variables appropriately.
Supervisor-2 modules can be installed on all Cisco MDS 9500 Series Directors.
The Cisco MDS 9513 Director does not support Supervisor-1 modules.
Generation 2 switching modules can be installed on all Cisco MDS 9000 Family switches, except
the Cisco MDS 9216 switch.
Generation 1 modules can be used with Cisco MDS 9000 Family switches. However, installing
Generation 1 modules in combination with Generation 2 switching modules in the same chassis
reduces the capabilities of the Generation 2 switching modules (see the
Generation 2, and Generation 3 Modules" section on page
Generation 1 and Generation 2 switching modules can be installed on Cisco MDS 9500 Family
switches with either Supervisor-1 modules or Supervisor-2 modules.
