Managing Dedicated Hot Spares

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:

1On the VD Mgmt screen, select Disk Group # and press <F2> to display the menu of available actions.

The available menu options appear.

2Select 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.

3Use the following instructions to create or delete a dedicated hot spare:

•Creating a dedicated hot spare

a Press the down-arrow key to highlight an available physical disk. b Press the spacebar to select the disk.

c Repeat step a to step b for each dedicated hot spare that you want to create.

An X is displayed beside the selected physical disk(s).

•Deleting a dedicated hot spare

a Use the down-arrow key to highlight a current hot spare. b Press the spacebar to de-select the disk.

c Repeat step a to step b for each dedicated hot spare that you want to delete.

4Press <Enter> to confirm the changes.

The VD Mgmt 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.
