Detaching a thin clone from a template volume breaks the dependency between the thin clone and the template volume. The following restrictions apply: • You cannot detach a thin clone if replication is enabled for the thin clone. • If you detach a thin clone from a template volume, the thin clone is converted to a standard volume and no longer shares space with the template volume. • The volume reserve for the thin clone increases by the amount of space the thin clone shares with the template volume. • When you detach a thin clone from a template volume that is bound to a member or has a RAID preference, the resulting volume does not inherit the binding or the RAID preference. To detach a thin clone from a template volume: 1. Click Volumes. 2. Expand Volumes and then select the thin clone. 3. Click Detach from template. 4. Confirm that you want to detach the thin clone. Convert a Template Volume to a Standard Volume You can create template volumes and then later convert them to standard volumes, with the following restrictions: • You cannot convert a template volume to a standard volume if thin clones are attached to the template volume. • If a template volume is configured for replication, you must disable replication before you convert a template volume to a volume. • Space used to store template replicas on the secondary group becomes unmanaged if you convert a template volume to a standard volume. To convert a template volume to a standard volume: 1. Click Volumes. 2. Expand Volumes and then select the volume name. 154 About Volumes

Detach a Thin Clone from a Template Volume
You can detach a thin clone from its template volume. Detaching a thin clone from a template volume breaks the dependency
between the thin clone and the template volume.
The following restrictions apply:
•
You cannot detach a thin clone if replication is enabled for the thin clone.
•
If you detach a thin clone from a template volume, the thin clone is converted to a standard volume and no longer shares space
with the template volume.
•
The volume reserve for the thin clone increases by the amount of space the thin clone shares with the template volume.
•
When you detach a thin clone from a template volume that is bound to a member or has a RAID preference, the resulting volume
does not inherit the binding or the RAID preference.
To detach a thin clone from a template volume:
1.
Click
Volumes
.
2.
Expand
Volumes
and then select the thin clone.
3.
Click
Detach from template
.
4.
Confirm
that you want to detach the thin clone.
Convert a Template Volume to a Standard Volume
You can create template volumes and then later convert them to standard volumes, with the following restrictions:
•
You cannot convert a template volume to a standard volume if thin clones are attached to the template volume.
•
If a template volume is
configured
for replication, you must disable replication before you convert a template volume to a volume.
•
Space used to store template replicas on the secondary group becomes unmanaged if you convert a template volume to a
standard volume.
To convert a template volume to a standard volume:
1.
Click
Volumes
.
2.
Expand
Volumes
and then select the volume name.
