2. Click Clone. The following dialog box appears: Clone Volume – Settings. Specify the new volume name and
description.
3. Click
Next.The following dialog box appears: Clone Volume – Space. Enable or disable thin provisioning
(only applicable to standard volumes). You can also change the thin provisioning space allocation settings for
the new volume:
• Minimum volume reserve
• In-use space warning threshold
• Maximum in-use space (maximum volume reserve
)
The group updates the values in the Pool Space table, based on the space settings. If the
new volume exceeds
the capacity of the pool, the table cell showing free pool space becomes red, displays a negative number, and
an error message appears.
Optionally, specify the amount of space, as
a percentage of the volume reserve, to reserve for snapshots of the
new volume.

Next. The following dialog box appears: Create Volume – iSCSI Access. Specify the following:
• Conditions that a computer must match to connect to the volume and its snapshots. Spec
ify a CHAP user
name, IP address, or iSCSI initiator name. This information generates an access control record that applies
to the volume and its snapshots. See About iSCSI target access controls.
• Permission for the volume, either read-write or
read-only
.
• Whether to allow or disallow (default) access to t
he volume and its snapshots by initiators with different
iSCSI qualified names (IQNs). See Multi-host access to targets.
5. Click

Click
Volumes in the far-left panel. The new volume appears in the list of volumes. See Displaying volumes on
page 9-6.
Note: Enabling
or disabling thin provisioning on a volume is an advanced operation. See Advanced volume
operations.
Modifying a volume name or description
Be aware of the potential impact of modifying a volume name:
• If you modify a volume name, the iSCSI target name (and any sn
apshot 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 identi
fy the replica set on the s
econdary by the
original volume name.
Requirement: A vo
lume name must be unique name and can be up to 63 alphanumeric characters (including
periods, hyphens, and colons). A volume description can be up to 127 alphanumeric characters.
