Description
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.
The setting for which RAID controller module owns
the disk group. Valid RAID controller module
identifiers are 0 or 1, where, 0 is the RAID controller
module in slot 0, and 1 is the RAID controller
module in slot1. If you do not specify an owner, the
RAID controller module firmware determines the
owner.
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.
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.
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.
