CLI Guide

Parameter Description
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.
NOTE: In configurations where disk groups consist of more than 32 virtual disks, the operation can
result in host I/O errors or internal RAID controller module reboots due to the expiration of the
timeout period before the operation completes. If you experience host I/O errors or internal RAID
controller module reboots, bring the host to a quiescent state and try the operation again.
