About Volumes
Volumes provide the storage allocation structure within the PS Series group.
To access storage in a PS Series group, you allocate portions of a storage pool to volumes. You can create a volume on a single group
member or one that spans multiple group members. You assign each volume a name, size, and a storage pool. The group
automatically load balances volume data across pool members.
Create a Volume
To create a new volume:
1. Click Volumes → Volumes.
2. In the Activities panel, click Create volume.
3. Follow the steps in the Create volume wizard to specify volume settings, space settings, iSCSI access points, access types,
and sector size.
4. Click Finish.
Modify a Volume Name or Description
You can modify a volume name or description any time after you create a volume, subject to the following considerations and
constraints:
• If you modify a volume name, the iSCSI target name (and any snapshot or replica set names) does not change. However, if you
modify a volume name, and the volume alias is set to be the same as the volume name, the alias also changes.
• If you modify the name of a replicated volume, you continue to identify the replica set on the secondary group by the original
volume name.
• Name can be up to 63 bytes and is case-insensitive. You can use any printable Unicode character except for ! " # $ % & ' ( ) *
+ , / ; < = > ?@ [ \ ] ^ _ ` { | } ~. First and last characters cannot be a period, hyphen, or colon. Fewer characters are accepted
for this eld if you type the value as a Unicode character string, which takes up a variable number of bytes, depending on the
specic character.
To modify volume information:
1. Click Volumes.
2. Expand Volumes and then select the volume name.
3. Click Modify settings.
4. Click the General tab to open the Modify Volume Settings – General dialog box.
5. Modify the name and, optionally, the description.
6. Click OK.
Modify a Volume Permission
A volume can have read-write or read-only permission, unless it is a template volume.
The following considerations apply:
• To change a volume permission to read-only, you must rst set the volume oine.
