Notes:
1. If there is insufficient unused space on the
disks in an array, you cannot add a distributed
spare without adding an additional disk and
transforming to an array with distributed sparing
enabled. The distributed spare option uses the
equivalent storage of one of the disks in the
array. For example: the total capacity of six
drives is being used in a RAID5 array, and you
have enabled distributed sparing, the capacity of
the array is the same as a four-drive RAID0. The
capacity of one disk is lost to the RAID5 parity
data, and the capacity of another disk is lost to
the distributed sparing option.
2. See "About Sparing Options".
To add a distributed spare while creating an array:
1.
On the Array menu, click Create.
2.
Configure the array.
3.
In the Distributed Spare field, click Enabled.
