Notes
In configurations with subsystems that have more than 32 logical drives, the timeout period might expire
before an operation completes. This causes host I/O errors or internal controller reboots. If such errors or
reboots occur, quiesce the host I/O and retry the operation.
When you use this command, you can specify one or more of the optional parameters.
You can apply these parameters to only one logical drive at a time:
v addCapacity
v segmentSize
v userLabel
v logicalUnitNumber
Add Capacity, Add Drives, and Segment Size
Setting the addCapacity parameter, the addDrives parameter, or the 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 show the progress of
long-running operations, use the show logicalDrive actionProgress command.

Description
The amount of data (in KB) that the controller
writes on a single disk drive in a logical drive
before writing data on the next disk drive. Valid
values are 8, 16, 32, 64, 128, 256, or 512.
The new name that you want to give an
existing logical drive. Enclose the new logical
drive name in double quotation marks (" ").
The setting to check the consistency of RAID
redundancy data on the stripes during read
operations. Do not use this operation for
non-redundant logical drives, for example RAID
Level 0. To check redundancy consistency, set
this parameter to TRUE. For no stripe checking,
set this parameter to FALSE.
The logical unit number for the access logical
drive. The logical unit number is the only
property that you can set for the access logical
drive.
Specific Volume-to-LUN mappings to an
individual host. This parameter also assigns the
host to a host group.
The name of the host to which the logical drive
is mapped. Enclose the host name in double
quotation marks (" ").
The name of the host group to which the logical
drive is mapped. Enclose the host group name
in double quotation marks (" "). defaultGroup
is the host group that contains the host to which
the logical drive is mapped.
