Parameter

Description

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 Attributes For A Disk Pool

Description

This command defines the properties for a virtual disk. You can use most parameters to define properties
for one or more virtual disks. You also can use some parameters to define properties for only one virtual
disk. The syntax definitions are separated to show which parameters apply to several virtual disks and
which apply to only one virtual disk. Also, the syntax for virtual disk mapping is listed separately.
