Command Line Interface (CLI)
141Modular SAN Array 1000 User Guide
STRIPE_SIZE=xxx—(optional) the stripe size to assign (in KB), where xxx
represents 8, 16, 32, 64, 128, or 256 Kilobytes.
RAID 0 uses stripe sizes 8, 16, 32, 64, 128, and 256 (Default: 128 KB)
RAID 1 uses stripe sizes 8, 16, 32, 64, 128, and 256 (Default: 128 KB)
RAID 5 uses stripe sizes 8, 16, 32, and 64 (Default: 16 KB)
RAID ADG uses stripe sizes 8, 16, 32, and 64 (Default: 16 KB)
SIZE=xxxxyy—(optional) how much of the available space on the indicated
drives is to be used for the LUN, where xxxx represents the LUN size and yy
indicates MB or GB. (When GB is entered, all return displays will be
converted to MB.) If no size is specified, the maximum available space of the
included disks will be assigned to the unit. See “Creating Multiple LUNs on a
Group of Drives” for an example of using the Size command option.
SPARE=DISKxxx—(optional) disk(s) to assign as a spare to the unit, where
xxx represents the disk number. More than one disk can be assigned as a
spare to a LUN.
MAXBOOT=ENABLE/DISABLE—(optional) changes the size of the boot partition.
Enable = 8-GB boot partition (default)
Disable = 4-GB boot partition
CACHE=ENABLE/DISABLE—(optional) determines whether to use the array
controller cache for the LUN.
Enable = (default) use the array controller cache
Disable = not use the array controller cache
Creating a Single LUN from a Group of Drives
To create one LUN from an individual drive or group of drives:
Example Command
CLI> ADD UNIT 0 DATA=”DISK101-DISK107 DISK110” RAID_LEVEL=ADG
STRIPE_SIZE=64
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, RAID type and size,
record the order
in which they are created
.
Command Options
0—LUN 0 is to be created.
DATA=”DISK101-DISK107 DISK110”—drives 1 through 7 and disk 10 in box
number 1 are to incorporated into the LUN.
RAID_LEVEL=ADG—RAID level ADG will be used when creating LUN 0.
STRIPE_SIZE=64—stripe size of 64 will be used when creating LUN 0.
