6.4 Adding Hot Spare Drives
Hot-swappable spare disk drives are supported. In the event of a drive failure, the controller will use either
a global spare or a dedicated spare to replace a failed drive that is a member of a fault tolerant array. The
process of configuring redundant arrays includes assigning one or more drives as hot spares.
Global spares are not assigned to a specific array and when created they can be used by any array as
the replacement drive.
A dedicated spare is assigned to a specific array and can only be used by that array. It should be the
same size or greater as the drive’s that comprise the array.
Spare Drive Use Rules:
– Drives must be equal to or greater than the capacity of the array drive members.
– You cannot mix drive types in the same array, all SATA or all SAS.
– You cannot mix drive types in the same enclosure column of drives, all SATA or all SAS.
– You cannot mix SATA drive MUX Transition card types, all A/P or all A/A MUX Transition cards.
Note: You may get a variety of messages, warnings, or failure notices when attempting to use a
non-supported drive configuration.
6.4.1 Assigning a Global Spare
1 From the Main screen, click a drive icon within the enclosure front view indicating “Available” that you
wish to make a global hot spare.
Note: There must be at least one drive online and available that meets the rules from above to be
assigned as a hot spare, and a configuration must exist (at least one array defined).
