How to Check System Health (CLI)
How to Check System Health (CLI)
Use the following procedure to check system health using the CLI.
1.
To select the update media, use the following CLI command:
zfs-appliance:maintenance system updates> select ak-nas@2013.06.05.0.0,1-1.6
2.
To upgrade the media and check system health, use the following CLI command:
zfs-appliance: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)

Healthcheck completed. There are no issues at this time which
would cause an upgrade to this media to be aborted.
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.
