Creating Multiple LUNs on a Group of Drives
To carve out multiple LUNs from a drive or group of drives, use the ADD UNIT
command and include the
SIZE= command option. Repeat the command using a
unique LUN ID for each LUN, along with the desired size parameter.
Example Command
CLI> ADD UNIT 1 DATA=”DISK111-DISK114” RAID_LEVEL=5
STRIPE_SIZE=32 SIZE=1000MB
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, and
record the order in which they are created
.
Command Options
1—LUN 1 is to be created.
DATA=”DISK111-DISK114”—drives 11 through 14 in box number 1 to the
LUN.
RAID_LEVEL=5—RAID 5 will be used when creating the LUN.
STRIPE_SIZE=32—stripe size of 32 will be used when creating the LUN.
SIZE=1000MB—1000 MB of the available space will be used for the LUN.
