使用 CLI 检查系统运行状况

要通过 CLI 执行更新运行状况检查，请在选择更新介质之后在 maintenance system updates 上下文中执行 upgrade 命令：

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