Command Line Interface (CLI)
Alternatively, you can use the automatic failover commands that
enable you to remove a failed drive and add a hot spare in its place.
The controller automatically assigns the new hot spare 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 hot spare assignment, all data is deleted from
the hot spare.
Through the CLI, you can:
■ Display a controller’s automatic failover status.
■ Enable 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
Enabling Automatic Failover
To enable automatic failover, use the
controller set
automatic_failover command with the /failover switch, as in
the following example:
AAC0> controller set automatic_failover
/failover_enabled=TRUE
Executing: controller set automatic_failover
/failover_enabled=TRUE
After running the controller set automatic_failover command,
use the
controller show automatic_failover command to verify
that automatic failover has been enabled. If necessary, you can now
replace a failed disk with a replacement disk.
