CLI Guide

segmentSize The amount of data (in KB) that the RAID controller
module writes on a single physical disk in a disk
group before writing data on the next physical disk.
Valid values are 8, 16, 32, 64, 128, 256, or 512.
dssPreallocate The setting to turn on or turn off allocating virtual
disk storage capacity for future segment size
changes. To turn on allocation, set this parameter
to TRUE. To turn off allocation, set this parameter
to FALSE.
SSID The storage array subsystem identifier of a virtual
disk. Use the show virtual disk command to
determine the storage array subsystem identifier.
owner The RAID controller module that owns the virtual
disk. 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 slot 1. 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.
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 – The disk group does not have data
assurance protection.
• enabled – The disk group has data assurance
protection. The disk group supports protected
information and is formatted with protection
information enabled.
NOTE: This option is only valid for
enablement, if the physical disks supports
DA.
allocateReservedSpace The setting to disable or enable the reserve
capacity on the physicalDisks in a disk group. The
RAID controller firmware automatically reserves
additional capacity on each drive when creating a
disk group. To prevent the RAID controller
firmware from reserving additional capacity on
each physicalDisk in a disk group, set this
parameter to FALSE. The default value is TRUE.
