CAUTION:
Decreasing the volume size is not recommended. If you shrink the volume in the CMC before shrinking
it from the server file system, your data will be corrupted or lost.

To edit a volume

1. In the navigation window, select the volume you want to edit.
2. Click Volume Tasks and select Edit Volume.
The Edit Volume window opens.

Changing the volume description

1. In the Description field, edit the description.
2. Click OK when you are finished.

Changing the cluster

If you change the cluster when editing a volume, the change causes the volume and all its data to
move to the target cluster.
Requirement
Either before or after changing the cluster, you must stop any applications that are accessing the
volume and log off all associated iSCSI sessions.
Even if using the HP DSM for MPIO, log off the volumes from the server, add the VIP or the individual
IP addresses of the storage systems in the other cluster, discover and mount volumes.
1. On the Edit Volume window, select the Advanced tab.
2. In the Cluster drop-down list, select a different cluster.
210 Using volumes
Requirements for Changing
The cluster must have sufficient storage systems and unallocated space to support the new
data protection level. For example, you just added more storage to a cluster and have more
capacity. You decide to change the data protection level for a volume from Network RAID-0
to Network RAID-10 to ensure you have redundancy for your data.
Before changing the size of a volume, refer to
er" on page 203
To increase the size of the volume:
• If you have enough free space in the cluster, simply enter the new size
• If you do not have enough free space in the cluster, delete volumes and/or snapshots, or
add a storage system to the cluster
To decrease the size of the volume (not recommended)
• If the volume has been or is mounted by any operating system, you must shrink the file
system on the volume before shrinking the volume in the CMC.
• You also should not decrease the size of the volume below the size needed for data cur-
rently stored on the volume.
