Troubleshooting Update Health Check Failures
Troubleshooting Update Health Check Failures
Prior to the actual 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.
FIGURE 83
Example BUI and CLI Update Health Checks Failures
hostname:maintenance system updates ak-nas@2013.06.05.0.0,1-1.6> upgrade
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.
Are you sure? (Y/N)
error: System is not in an upgradeable state: prerequisite healthcheck reports
problems.
See alert log for more.
Resolving Health Check Alerts
After an update health check failure, you can review the Alert Log and take action to resolve
each failure based on the message in the log. The following table lists the update health
check failures that can block an update, and describes the associated Alert Log message and
recommended order of steps you can take to resolve the issue. For component faults, follow
the instructions for removal and installation found in the maintenance procedures for your
controller.
