The name of an SSA RAID Manager. SSA RAID Managers are devices
that control SSA RAID arrays.
The type of the SSA RAID array.
For a RAID-0 or a RAID-5 array, member disks are the disk drives that are
to be added to the SSA RAID array. The array must consist of disk drives
that are in the same loop.
The primary disk drive of a RAID-1 array. A RAID-1 array must consist of
two disk drives, one primary and one secondary, that are in the same loop.
The data that is contained on the primary disk drive is a mirror copy of the
data that is contained on the secondary disk drive.
The secondary disk drive of a RAID-1 array. A RAID-1 array must consist
of two disk drives, one primary and one secondary, that are in the same
loop. The data that is contained on the secondary disk drive is a mirror
copy of the data that is contained on the primary disk drive.
The primary disk drives of a RAID-10 array. A RAID-10 array consists of an
even-numbered quantity (4 through 16) of disk drives that are in the same
loop. The minimum RAID-10 array consists of two primary and two
secondary disk drives. The data that is contained on the primary disk
drives is a mirror copy of the data that is contained on the secondary disk
drives. Ensure that you choose a quantity of primary disk drives that
matches the quantity of secondary disk drives.
The secondary disk drives of a RAID-10 array. A RAID-10 array consists of
an even-numbered quantity (4 through 16) of disk drives that are in the
same loop. The data that is contained on the secondary disk drives is a
mirror copy of the data that is contained on the primary disk drives. Ensure
that you choose a quantity of secondary disk drives that matches the
quantity of primary disk drives.
The maximum amount of contiguous data that is mapped to a single
member disk drive.
If you enable this option, the SSA RAID Manager can use any available
hot spare disk drive to replace a failing member disk drive dynamically. The
failing disk drive is rejected from the array, and the hot spare disk drive is
put into the available place.
