Parameter

Description

 

 

capacity

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.

 

NOTE: Add a space 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

RAID controller module that owns the virtual disk.

 

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.

 

NOTE: The owner parameter defines which

 

RAID controller module owns the virtual disk.

 

The preferred RAID controller module

 

ownership of a virtual disk is the RAID

 

controller module that currently owns the disk

 

group.

cacheReadPrefetch

The setting to turn on or turn off cache read

 

prefetch. To turn on cache read prefetch, set this

 

parameter to TRUE. To turn off cache read

 

prefetch, set this parameter to FALSE.

segmentSize

Amount of data (in kilobytes) 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. For information about the

 

segmentSize parameter, see Using The Auto

 

Configure Command.

usageHint

The settings for both the cacheReadPrefetch

 

parameter and the segmentSize parameter

 

should be the 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.

dssPreAllocate

The setting to make sure that reserve capacity is

 

allocated for future segment size increases. The

 

default value is TRUE.
