In this sample case, the supervisor failed when the standby was reloaded or when the supervisor was
replaced with a new one. It was discovered that the failed supervisor either had its version of code
changed, or the running configuration on the active supervisor was not saved with the appropriate boot
parameters. In either case, the problem was mismatched code on the active and standby supervisors. One
clue that indicated the mismatched code was a heartbeat error on the active supervisor. Because of this
error, the current Flash images were unable to be copied from the active supervisor to the standby.
The workaround was to copy the images to CompactFlash, switch consoles, and load code from
CompactFlash onto the second supervisor. The second supervisor was at a loader prompt, which is
indicative of missing boot statements. When a dir slot0: CLI command was entered, none of the images
appeared. This may have been the result of mismatched images on supervisors or to not having current
images in Flash memory on the supervisor. Entering a copy slot0: bootflash: CLI command copied the
images anyway. Once the images were loaded on the second supervisor and the boot statements were
confirmed and saved on the active supervisor, the supervisor loaded and came up in standby-ha mode.
