CLI Guide

For virtual storage, if overcommit is disabled, expansion is restricted to the space available in the pool that
contains the volume. If overcommit is enabled, the volume size can exceed the physical capacity of the pool.
The maximum volume size is 140 TB (128 TiB). To see whether overcommit is enabled, use the show pools
command.
For linear storage, if insufficient space is available for expansion in the disk group, first expand the disk group
by using expand vdisk.
You cannot expand the secondary volume of a replication set. However, you can expand the primary volume
of a replication set, which automatically expands its secondary volume—even if replication is in progress.

Syntax
expand volume
size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB] | max
volume
Parameters
size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB] | max
Specifies either:
• The amount of space to add to the volume. The unit is optional (B represents bytes). If base 2 is in use,
whether you specify a base-2 or base-10 unit, the resulting size will be in base 2. If no unit is specified, the
default is 512-byte blocks.
• max: For linear storage, expand the volume to fill the available space in the disk group.
volume
The name or serial number of the volume to expand. A name that includes a space must be enclosed in
double quotes.
Examples
Expand volume V1 by 100 GB.
# expand volume size 100GB V1

fail
Description
Forces the partner controller module to crash for a non-maskable interrupt. The command causes the crash
by issuing an internal kill command to the Storage Controller in the partner controller module. This might be
helpful to gather debug information that is only available via a crash dump.
NOTE: Failing a controller module will reduce system redundancy and performance, and
increase risk of data unavailability due to the reduced redundancy. If you are uncertain
whether to use this command, contact technical support for assistance.

Syntax
fail
controller a|b
Parameters
controller a|b
Specifies whether to kill controller A or B. You cannot kill the controller on which the command is issued.
Examples From controller A, fail controller B.
# fail controller b
