Troubleshooting Update Health Check Failures

Prior to the actual software update, health checks are performed automatically when an update is started. If an update health check fails, it can cause an update to abort (see following example). Update health checks only validate issues that can impact updates.

Example BUI and CLI Update Health Checks Failures

This procedure will consume several minutes and requires a system reboot upon
successful update, but can be aborted with [Control-C] at any time prior to
reboot. A health check will validate system readiness before an update is
attempted, and may also be executed independently using the check command.
