Valid physical disk type is SAS. This parameter is not required if only one type of physical disk is in the storage array. RAID level of the disk group that contains the physical disks in the storage array. Valid RAID levels are 0, 1, 5 or 6. Number of physical disks in a disk group in the storage array. This number depends on the capacity of the physical disks. Integer values are required. For information about the number of physical disks that you can use in a disk group, see Enclosure Loss Protection. Number of disk groups in the storage array. Use integer values. Number of equal-capacity virtual disks per disk group. Use integer values. Number of hot spares desired in the storage array. Use integer values. For information about hot spares, see Assigning Global Hot Spares. 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. 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 setting to specify the security level when creating the disk groups and all associated virtual disks. These settings are valid: • 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. Show Storage Array Host Topology This command returns storage partition topology, host type labels, and host type index for the host storage array. 201

Parameters
Parameter
Description
physicalDiskType
Type of physical disk to use for the storage array. Valid
physical disk type is SAS. This parameter is not required if
only one type of physical disk is in the storage array.
raidLevel
RAID level of the disk group that contains the physical
disks in the storage array. Valid RAID levels are
0
,
1
,
5
or
6
.
diskGroupWidth
Number of physical disks in a disk group in the storage
array. This number depends on the capacity of the
physical disks. Integer values are required. For
information about the number of physical disks that you
can use in a disk group, see Enclosure Loss Protection.
diskGroupCount
Number of disk groups in the storage array. Use integer
values.
virtualDisksPerGroupCount
Number of equal-capacity virtual disks per disk group. Use
integer values.
hotSpareCount
Number of hot spares desired 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. These settings
are valid:
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.
Show Storage Array Host Topology
This command returns storage partition topology, host type labels, and host type index for the host storage array.
