Parameter Description
virtualDisksPerGroupCount
Number of equal-capacity virtual disks per disk
group. Use integer values.
hotSpareCount
Number of hot spares in the storage array. Use
integer values. For information about hot spares,
see Assigning Global Hot Spares.
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.
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.
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.
• capable—The disk group and virtual disks are
capable of having security set, but security has
not been enabled.
• enabled—The disk group and virtual disks have
security enabled.
dataAssurance
The setting to specify that a disk group, and the
virtual disks within the disk group, has data
assurance protection to make sure that the data
maintains its integrity. When you use this
parameter, only protected physical disks can be
used for the disk group. These settings are valid:
• none - No explicit data assurance is defined.
The disk group will be comprised of virtual disks
that may or may not have data assurance,
depending on the availability of data assurance
enabled physical disks. Data Assurance is
enabled on virtual disks created on disk groups
that support data assurance. If only data
assurance physical disks are available, the disk
groups will be data assurance enabled.
• enabled - The disk group has data assurance
protection. The disk group supports protected
information and is formatted with protection
information enabled.
