growvv
DESCRIPTION
The growvv command increases the size of a virtual volume.
SYNTAX
growvv <VV_name> <size>[g|G|t|T]
AUTHORITY
Super, Edit
Any role granted the vv_grow right.
NOTE: You need access to the domain of the specified group (<group_name>) in order to run
this command.
OPTIONS
-f
Suppresses the requested confirmation before growing a virtual volume size from under 2 T to over
2 T.
SPECIFIERS
<VV_name>
The name of the volume to be grown.
<size>[g|G|t|T]
The size to be added to the volume’s user space. The size is specified in multiples of 256 MB. You
can optionally specify the grow size in gigabytes (g or G) or in terabytes (t or T).
RESTRICTIONS
In order to grow a virtual volume in a Remote Copy group, that group must first be stopped.
You must grow the corresponding virtual volume on the secondary system by the same amount
or the Remote Copy group will not restart.
EXAMPLES
The following example increases the size of virtual volume vv1 by two terabytes:
# growvv vv1 2t
NOTES
Ensure that there is sufficient space to mirror the grow of the volume on the secondary system before
growing the volume on the primary system.
The grow operations of Remote Copy volumes are coordinated between the primary and secondary
targets. A coordinated grow can be started from either the primary or secondary target. Volumes
on remote targets are grown to the intended size of the local volume. If a target cannot be contacted
or Remote Copy is not started, only the local volume will be grown. A check is first made to see if
the local and remote volumes can be grown by the requested amount. If this succeeds, all the
volumes are grown; however, if other volumes are grown during this process, it is possible that
remote volumes are grown and the local volume is not. If this occurs, remote volumes must be
grown manually before the group can be started.
