Creating Global Hot Spares
A global hot spare can be used to replace a failed physical disk in any redundant array as long as the capacity
of the global hot spare is equal to or larger than the coerced capacity of the failed physical disk.

NOTE:
To replace a failed physical disk global hot spares must use the same drive technology and must be
equal or greater in size.
5
Select additional physical disks if desired and follow the previous steps to change them to global
hot spares.
Removing Global or Dedicated Hot Spares
You can remove one global or dedicated hot spare at a time on the PD Mgmt screen . Perform the

capacity of the smallest physical disk.
5
Select additional hot spares if desired and follow the previous steps to remove them.
NOTE:
On the PERC 5/i RAID controller, after you delete a virtual disk, any hot spares dedicated to that virtual
disk become global hot spares.
