Creating Dedicated Spares or a Spare Pool
Each RAID 1, 0/1, or 5 array can have dedicated spares , which
automatically replace failed disks only for that array. You can create
dedicated spares when you create the array, or you can add them to
the array at a later time. Each array controller can have a
spare pool of
multiple disks which automatically replace a failed disk on any
array on the controller.
We recommend using a spare pool instead of dedicated spares if you
have two or more arrays on a controller. Pool spares give you more
flexibility and provide good data protection with fewer disks than is
required for dedicated spares.
Pool spares must be at least as large as the array’s member size.
Some physical drives may be larger than the member size.
Note:
Adaptec CI/O Management Software is automatically
configured to test all spares on the system once a day to
assure they are always available to replace failed disks in
arrays. We recommend that you leave this default setting.
Follow these steps to add a dedicated spare or a pool spare:
Caution:
Before designating a disk as a spare, back up all
data on the disk. All contents of a disk selected as a spare
will be lost!
