Group Administration Advanced volume operations
10–9
Note: When you convert to a template volume, the group disables any schedules that include the volume. If you
later convert the template volume to a standard volume, the group does not automatically enable the
schedules.
Requirement: Before converting to a templat
e volume, make sure the standard volume contains all the data that is
shared with the thin clones. Also, make sure that the standard volume has sufficient free space to
hold the approximate amount of data that you write to each thin clone.
For example, if the reported size of the template
volume is 1 GB, and in-use space is 900 MB, you
can write approximately 100 MB to each thin clone before you must increase the thin clone size.
1. Click
Volumes, then expand Volumes, then select the volume, and then click Convert to template.
2. Confirm that you want to convert to a template vol
ume.
Converting a template volume to a standard volume
Restriction: You cannot convert a template volume to a standard volume if thin clones are attached to
the template volume or if the template volume is configured for replication.
Restriction: Yo
u must disable replication before you can convert a template volume to a volume.
Note: Space
used to store template replicas on the secondary group becomes unmanaged if you convert a template
volume to a standard volume.
1. Click
Volumes, then expand Volumes, then select the volume, and then click Convert to volume.
2. Confirm that you want to convert to a volume.
Creating a thin clone

Detaching a thin clone from a template volume
Detaching a thin clone from a template volume breaks the dependency between the thin clone and the template
volume.
