Changing Dedicated Spare Disk Drives

You can use the Add Spare button in the Reconfigure Array dialog
box to change the spare disk drives assigned to an array if you are
also making other changes to the array.
However, if all you want to do is change the spare disk drives
assigned to an array, don't do so from the Reconfigure Array dialog
box. (See Managing Spares Assigned to an Array on page 7-2 instead.)
Although the Add Spare button always appears to be active, it
won't add a spare to an array unless other changes are being made
to the array as well.
Note: Assigning a spare to an array does not reserve space
on the spare for the array. If there is sufficient free space on
the spare, the controller will use that spare during failover.
See Chapter 7, Managing Spares.
To change the spare disk drives while making other array changes:
1 From the Reconfigure Array dialog box, select the disk drives
you want to add or remove as spares.
– To add spare drives, select one or more drives in the Available
Drives list and click Add Spare. The disk drives you selected
move to the Selected Drives list and display a spare icon and
yellow asterisk showing that they are new spares for this
array. See Understanding the Selected Disk Drive Icons on
page 2-9.
– To remove spare disk drives, select one or more spares in the
Selected Drives list and click Remove.
