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.
