Creating Global Hot Spares

1. Press the down-arrow key to highlight a physical disk to change to a global hot spare.
2. Press <F2> to display the menu of available actions.
3. Press the down-arrow key to highlight Make Global HS and press <Enter>.
The physical disk is changed to a global hot spare. The status of the physical disk as a global hot spare is displayed
under the heading State.
NOTE: To replace a failed physical disk global hot spares must use the same disk technology and must be
equal or greater in size.
4. Select additional physical disks if desired and follow the previous steps to change them to global hot spares.
Removing Global Or Dedicated Hot Spares

capacity of the smallest physical disk.
5. Select additional hot spares if desired and follow step 1 to step 4 to remove them.
