Caution: The controller deletes any data on the replacement
disk when automatic spare is enabled and you remove the
failed disk and insert the replacement disk in the failed
disk’s slot.
Note: The automatic spare feature works only with disks
that reside in a SAF-TE enclosure management device.
The CLI allows you to do the following:
■ Display a controller’s automatic spare status
■ Enable automatic spare
To display a controller’s automatic spare status, use the
controller show automatic_spare command, as in the
following example. In the example, the automatic spare feature is
indicated as DISABLED.
HPN0> controller show automatic_ spare
Executing: controller show automatic_ spare
Automatic spare DISABLED
To enable automatic spare, use the controller set
automatic_spare command with the / spare switch, as in the
following example:
HPN0> controller set automatic_spare /spare_enabled=TRUE
Executing: controller set automatic_spare /spare_enabled=TRUE
After running the controller set automatic_spare
command, use the controller show automatic_spare
command again to verify that automatic spare has been enabled.
You can now replace a failed disk with a replacement disk, if
necessary.
