Troubleshooting a Nondisruptive Upgrade on a Fabric Switch
When a nondisruptive upgrade begins, the system notifies all services that an upgrade is about to start,
and finds out whether or not the upgrade can proceed. If a service cannot allow the upgrade to proceed
at this time (for example, FSPF timers are not configured to the default value, or a CFS operation is in
progress), then the service will abort the upgrade. In such a context, you will be prompted to enter the
show install all failure-reason command to determine the reason why the upgrade cannot proceed.

Please identify the cause of the failure, and try 'install all' again.

If there are any failures for whatever reason (a save runtime state failure or linecard upgrade failure) once
the upgrade is already in progress, then the switch will be rebooted disruptively because the changes
cannot be rolled back. In such cases the upgrade has failed; you are not prompted to enter the show
install all failure-reason command, and entering it will not yield any useful information.
If further assistance is required to determine why an upgrade is unsuccessful, you should collect the
details from the show tech-support command output, and the console output from the installation, if
available.
