Figure 270 Booting the standby management module to secondary flash

CAUTION: If you have booted one module out of primary flash and one module out of secondary

flash, and the secondary flash is running a prior software version because the latest version was

never copied over from the primary flash, you will have a software version mismatch. The

configuration file may not work with that software version.

The standby module enters warm-standby redundancy mode and boots to a certain point, syncs

basic files such as the config and security files, and finishes booting only if the active management

module fails or you choose to change which module is the active module..

Additionally, if a switchover occurs, or if you reboot to make the standby module become the

active module, any configuration file changes made may not work on the active module if it has

a different software version from the standby module.

When you enter the show redundancy command and a software version mismatch exists, a

warning message is displayed, as shown at the bottom of Figure 271 (page 491).
