Configuring and Managing RAID 97
Managing Dedicated Hot Spares
A dedicated hot spare automatically replaces a failed physical disk only in the
selected disk group which the hot spare is part of. A dedicated hot spare is
used before a global hot spare is used. You can create dedicated hot spares or
delete them on the VD Mgmt screen. Perform the following steps to create or
delete dedicated hot spares:
1
On the
VD Mgmt
screen, select
Disk Group #
and press <F2> to display
the menu of available actions.
The available menu options appear.
2
Select
Manage Ded. HS
and press <Enter>.
A screen displays a list of the current dedicated hot spares with an
X
beside
them and the physical disks that are available to create dedicated hot spares.
NOTE: The utility allows only disks of the same disk technology and of equal
or greater size to be selected as dedicated hot spare.

screen displays the updated list of hot spares under the
Hot spares
heading.
NOTE: If a global hot spare or dedicated hot spare is removed, reinserted and
imported, it regains its status as a hot spare. A dedicated hot spare becomes
a global hot spare when the disk group it was assigned to protect is no longer
present during import.
