Parameter

Description

 

 

 

• allMedia — Use this option when you want to use all types of

 

physical disk media that are in the expansion enclosure.

physicalDiskType

The type of physical disk that you want to use in the virtual disk.

 

You cannot mix physical disk types. The valid physical disk type is

 

SAS. You must specify a physical disk type.

capacity

The size of the virtual disk that you are adding to the storage

 

array. Size is defined in units of bytes, KB, MB, GB, or TB. The

 

following examples show the syntax:

 

capacity=500 bytes

 

capacity=2 GB

 

NOTE: A space must be added between the last digit and the

 

size (bytes, KB, MB, or GB) for values greater than 9. If you

 

do not specify a capacity, all the available physical disk

 

capacity in the disk group is used. If you do not specify the

 

capacity unit, bytes is used as the default unit.

owner

The setting for which RAID controller module owns the disk

 

group. Valid RAID controller module identifier values are 0 and 1.

 

The identifier value is 0 for the RAID controller module on the top

 

and 1 for the RAID controller module on the bottom when

 

viewed from the rear of the enclosure. If you do not specify an

 

owner, the RAID controller module firmware determines the

 

owner.

cacheReadPrefetch

The setting to turn on or turn off cache read prefetch. To turn off

 

cache read prefetch, set this parameter to FALSE. To turn on

 

cache read prefetch, set this parameter to TRUE.

segmentSize

The amount of data (in KB) that the RAID controller module

 

writes on a single physical disk in a virtual disk before writing data

 

on the next physical disk. Valid values are 8, 16, 32, 64, 128, 256,

 

or 512.

usageHint

The setting for both the cacheReadPrefetch parameter and

 

the segmentSize parameter to be default values. The default

 

values are based on the typical I/O usage pattern of the

 

application that is using the virtual disk. Valid values are

 

fileSystem, dataBase, or multiMedia.

enclosureLossProtect

The setting to enforce enclosure loss protection when you create

 

the disk group. To enforce enclosure loss protection, set this

 

parameter to TRUE. The default value is FALSE.

drawerLossProtect

The setting to enforce drawer loss protection when you create

 

the disk group. To enforce drawer loss protection, set this

 

parameter to TRUE. The default value is FALSE.

securityType

The setting to specify the security level when creating the disk

 

groups and all associated virtual disks.

 

none—The disk group and virtual disks are not secure.
