Command Line Interface Managing Failover Options and Hotspares To assign one or more hotspares to a single array, use the container set failover command. To assign one or more spare disks for all arrays, use the container set global_failover command. These commands allow you to add hotspares to an array prior to a drive failure so that the array contains the resources it needs to survive a failure. Alternatively, you can use the automatic failover commands that allow you to remove a failed drive and add a hotspare in its place. The controller automatically assigns the new hotspare to replace the failed drive without your having to first assign it using the container set failover or container set global_failover commands. Note: Automatic failover works only with disks that reside in an SAF-TE- or SES-enabled enclosure. ! Caution: During hotspare assignment, all data is deleted from the hotspare. The following failover topics are discussed: ■ Displaying the Controller's Automatic Failover Status ■ Enabling Automatic Failover Displaying the Controller's Automatic Failover Status To display a controller's automatic failover status, use the controller show automatic_failover command. In the following example, automatic failover is DISABLED: AAC0> controller show automatic_failover Executing: controller show automatic_failover Automatic failover DISABLED D-8
