开始之前
完成准备软件升级。
请勿选择 Diagnostic Reboot（诊断重新引导）。请等待重新引导完成，然后再继续。

controller-a:maintenance system updates ak-nas@2013.06.05.6.3,1-2.1.7.1> check
You have requested to run checks associated with waiting upgrade media. This
will execute the same set of checks as will be performed as part of any upgrade
attempt to this media, and will highlight conditions that would prevent
successful upgrade. No actual upgrade will be attempted, and the checks
performed are of static system state and non-invasive. Do you wish to continue?
Are you sure? (Y/N) y
作为更新的一部分，将自动重新引导控制器 A。
controller-a:maintenance system updates ak-nas@2013.06.05.6.3,1-2.1.7.1> 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.

在以下示例中，控制器 A 的状态是 AKCS_STRIPPED，描述为 "Ready (waiting for failback)"（就绪（等待故障恢复））。
controller-a:> configuration cluster show
state = AKCS_STRIPPED
description = Ready (waiting for failback)
...
peer_state = AKCS_OWNER
peer_description = Active (takeover completed)
有关群集状态的信息，请参见Oracle ZFS Storage Appliance 管理指南，发行版 OS8.8.0 中的 群集的接管和故障恢复。

在以下示例中，控制器 B 的状态是 AKCS_OWNER，描述为 "Active (takeover completed)"（活动（接管已完成））。
controller-b:> configuration cluster show
state = AKCS_OWNER
description = Active (takeover completed)
...
peer_state = AKCS_STRIPPED
peer_description = Ready (waiting for failback)
controller-b:> configuration cluster failback
Continuing will immediately fail back the resources assigned to the cluster
peer. This may result in clients experiencing a slight delay in service.
