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. Conrm 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 congured 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.
