Partitioning a Storageset or Disk Drive
See “Planning Partitions,” page 4–34, for details about partitioning a storage unit.
To partition a storageset or disk drive:
1. Add the storageset or disk drive to the controller’s list of storagesets and specify
the disk drives it contains. Use the following command:
ADD storageset-name DISK nnnnn DISK nnnnn
or
ADD DISK DIsk nnnnn ptl-location
Do not split partitioned units across ports. They must be on a single port. The
subsystem assigns units 0-99 to Port 1; units 100-199 are assigned to Port 2.
2. Initialize the storageset or disk drive. If you want to set any Initialize switches,
you must do so in this step. Use the following command:
INITIALIZE storageset-name switch
3. Create each partition in the storageset or disk drive by indicating the partition’s
size. Use the following command:
CREATE_PARTITION storageset-name SIZE= n
where n is the percentage of the disk drive or storageset that will be assigned to
the partition. Enter SIZE=LARGEST to let the controller assign the largest free
space available to the partition.
4. Verify the partitions, using the following command:
SHOW storageset-name
The partition number appears in the first column, followed by the size and start-
ing block of each partition.
5. Present each partition to the host by giving it a unit number the host can
recognize. (You can skip this step until you are ready to put the partitions online.)
Optionally, you can append Unit switch values. If you do not specify switch
values, the default values are applied.
