DEVICE_COUNT=

The number of physical disks to use for the default disk group of this system. The 
limit is the number of available disks in the storage system. The default and 
minimum value is 8.

DISKGROUP_DISKTYPE=

This parameter determines the types of disks to be considered for creating the disk 
group. The default value is ONLINE.

ONLINE: Online Fibre channel disks are considered for creating the default disk 
group.

NEAR-ONLINE: Near-Online Fibre channel disks are considered for creating the 
default disk group.

SPARE_POLICY=

This parameter determines the amount, if any, of storage space set aside for safety 
in the event that disks fail. The default SPARE_POLICY is SINGLE.

■

NONE—Reserves no space within a disk group to allow for data 
reconstruction for failure of disk drives.

■

SINGLE—Reserves space within a disk group to allow for data 
reconstruction for failure of a single disk drive. This is the default.

■

DOUBLE—Reserves space within a disk group to allow for data 
reconstruction for failure of two disk drives.

Note:  

The space set aside is not in numbers of physical disks. It is the equivalent 

amount of storage space spread across all disks.

Example

ADD SYSTEM payroll DEVICE_COUNT=12 SPARE_POLICY=SINGLE

This example creates an initialized system payroll with 12 physical disks and a 
spare policy of SINGLE.
