add unit
Description Adds a new LUN comprised of one or more hard drives.
NOTE:
Maintain a record of the units as they are created. These Unit ID numbers
are used in other CLI commands. In addition to recording the unit
number, the drives included, and the RAID type and size, record the order
in which they are created.
Syntax
add unit <unit_number> raid_level=<raid_level>
data=<diskrange> [spare=<diskrange>]
[stripe_size=<stripe_size>] [size=<size>GB|MB]
[max_boot=enable|disable] [cache=enable|disable]
Operands >unit_number>
The number to assign to the new LUN (0-31).
raid_level=<raid_level>
The RAID fault-tolerance level to use. Use one of the following values:
• 0 = RAID 0 (no fault tolerance)
• 1 = RAID 1 (mirroring)
• 5 = RAID 5 (distributed parity)
• 6 = RAID 6 (Advanced Data Guarding)
NOTE:
If more than one pair of drives are included in a RAID 1 array, the
data is striped across the first half of the drives in the array, and then
each drive is mirrored to a drive in the remaining half of the drives for
fault tolerance. This method is referred to as RAID 1+0.
data=<diskrange>
The disk or disks to be used as primary data disks in the LUN. See the
description of <diskrange> below.
spare=<diskrange>
[Optional] The disk or disks to be used as spare disks in the LUN. See the
description of <diskrange> below.
<diskrange>
The disks to include, including a single disk, a range of consecutive disks, or
multiple series of single or consecutive disks. (If multiple series of single or
consecutive disks is entered, the entry must be encased in quotation marks.)
Disks are identified as disk<xyy>, where <x> is the box number (1-8) and
<yy> is the bay number (01-14). For example:
• disk101
• disk101-disk105
• "disk101 disk112-disk202 disk314"
stripe_size=<stripe_size>
