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

AAC0> controller show automatic_failover
Executing: controller show automatic_failover
Automatic failover DISABLED
Enabling Automatic Failover
