expand volume

This command executes volume expansion (LUN concatenation). It adds free space to expand the capacity of
a currently registered volume, allowing free space to be assigned efficiently. In addition, this command can
expand the capacity of Thin provisioning volume (TPV). SDVs, SDPVs, and WSVs cannot be expanded.
The "expand flexible-tier-volume" command is used to expand Flexible Tier Volumes (FTVs).
■ Syntax
expand volume {-volume-number
[{-rg-number
■ Parameter
-volume-number
or
-volume-name
-rg-number
or
-rg-name
-size
■ Example(s)
The following example expands the volume named "VOL001" as a new 800GB area in RAID group #5:
CLI > expand volume -volume-name VOL001 -rg-number 5 -size 800gb
volume_number
rg_numbers rg_names
| -rg-name
This parameter specifies the volume identifier to be expanded. Only one volume can be
specified at the same time. For details, refer to
Optional. This parameter specifies the RAID group identifiers to which the volume will belong
after expansion. One or more RAID groups can be specified at the same time (up to a
maximum of 15). If two or more RAID groups are specified, they must be specified in the same
order as the expansion size parameter. For details, refer to
22).
This parameter cannot be specified for a Thin provisioning volume (TPV).
This parameter should be specified when the volume type is NOT a Thin provisioning volume
(TPV).
This parameter specifies the capacity that is to be added when expanding a volume. When
expanding a TPV, specify the capacity that is required after expansion is performed. Terabytes
(TB), gigabytes (GB), or megabytes (MB) can be specified. For volume expansion,
concatenated source volumes and volumes that are to be concatenated must be 1GB or more.
Multiple parameters can be specified, but these parameters must match the equivalent RAID
group identifiers that are specified in the previous parameter.
Example: 1tb, 120gb, 512mb
