CLI Command Descriptions

Switches

The following switch is associated with the CREATE_PARTITION command:

•

SIZE

SIZE=percent
SIZE=LARGEST

Specifies the size of the partition to be created as a percentage of the total
container’s storageset size:

•

Specify SIZE=percent to create a partition on the specified container that is a
percentage of the container’s total capacity. Up to eight partitions may be
created on any one container.

NOTE: The resulting partition is slightly smaller than the size specified because metadata also
occupies some of the space allocated to the partition.

•

Specify SIZE=LARGEST to:

•

Have the controller create the largest partition possible from unused space on
the disk or storageset.

•

Create the last partition on a container. Because the remaining space is not
equal to an exact percentage value, specifying LARGEST allows you to
optimize use of the remaining space.

Example

To create a RAIDset named RAID9, divide it into four equal parts, and create
host-addressable units for each partition, enter:

ADD RAIDSETS RAID9 DISK10000 DISK20100 DISK30200
INITIALIZE RAID9
CREATE_PARTITION RAID9 SIZE=25
CREATE_PARTITION RAID9 SIZE=25
CREATE_PARTITION RAID9 SIZE=25
CREATE_PARTITION RAID9 SIZE=LARGEST
ADD UNITS D101 RAID9 PARTITION=1
ADD UNITS D102 RAID9 PARTITION=2
ADD UNITS D103 RAID9 PARTITION=3
ADD UNITS D104 RAID9 PARTITION=4
