Parameter segmentSize userLabel preReadRedundancyCheck accessVirtualDisk logicalUnitNumber host hostGroup Description 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. Specifies the new name to give an existing virtual disk. You must put quotation marks (" ") around the new virtual disk name. The setting to check the consistency of RAID redundancy data on the stripes during read operations. Do not use this operation for nonredundant virtual disks, for example RAID Level 0. To check redundancy consistency, set this parameter to TRUE. For no stripe checking, set this parameter to FALSE. Specifies the logical unit number for the access virtual disk. The logical unit number is the only property that you can set for the access virtual disk. NOTE: If you specify the accessVirtualDisk parameter, the only property that you can set is the logicalUnitNumber. Defines specific virtual disk-to-LUN mappings to an individual host or assigns the host to a host group. Specifies the name of the host to which the virtual disk is mapped. You must put quotation marks (" ") around the host name. Specifies the name of the host group to which the virtual disk is mapped. You must put quotation marks (" ") around the host group name. NOTE: When using this command, you can specify one or more of the parameters. You do not, however, need to use all of the parameters. NOTE: You can apply the addCapacity, segmentSize, userLabel, and logicalUnitNumber parameters to only one virtual disk at a time. NOTE: Setting the addCapacity, addPhysicalDisks, or segmentSize parameter starts a long-running operation that you cannot stop. These long-running operations are performed in the background and do not prevent you from running other commands. To display the progress of long-running operations, use the show virtualDisk actionProgress command. Set Virtual Disk Copy This command defines the properties for a virtual disk copy pair. 190

Parameter
Description
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.
userLabel
Specifies the new name to give an existing virtual disk.
You must put quotation marks (" ") around the new virtual
disk name.
preReadRedundancyCheck
The setting to check the consistency of RAID redundancy
data on the stripes during read operations. Do not use this
operation for nonredundant virtual disks, for example
RAID Level 0. To check redundancy consistency, set this
parameter to
TRUE
. For no stripe checking, set this
parameter to
FALSE
.
accessVirtualDisk
Specifies the logical unit number for the access virtual
disk. The logical unit number is the only property that you
can set for the access virtual disk.
NOTE:
If you specify the
accessVirtualDisk
parameter, the only property that you can set is the
logicalUnitNumber
.
logicalUnitNumber
Defines specific virtual disk-to-LUN mappings to an
individual host or assigns the host to a host group.
host
Specifies the name of the host to which the virtual disk is
mapped. You must put quotation marks (" ") around the
host name.
hostGroup
Specifies the name of the host group to which the virtual
disk is mapped. You must put quotation marks (" ") around
the host group name.
NOTE:
When using this command, you can specify one or more of the parameters. You do not, however, need to
use all of the parameters.
NOTE:
You can apply the
addCapacity
,
segmentSize
,
userLabel
, and
logicalUnitNumber
parameters to only one virtual disk at a time.
NOTE:
Setting the
addCapacity
,
addPhysicalDisks
, or
segmentSize
parameter starts a long-running
operation that you cannot stop. These long-running operations are performed in the background and do not
prevent you from running other commands. To display the progress of long-running operations, use the
show
virtualDisk actionProgress
command.
Set Virtual Disk Copy
This command defines the properties for a virtual disk copy pair.
