Resetting an Unregistered LUSE Volume
When you create a LUSE volume, it will remain highlighted in blue bold italics until you register it
to the storage system by clicking Apply. A LUSE volume in blue bold italics indicates that you can
reset this LUSE volume to the state it was in before it was created.
This is a function that allows you to reset an unregistered LUSE volume to the state it was in before
it was created. However, it does not allow you to recover any LUSE volumes that have been released
to the state they were in before they were created. Therefore, if the LUSE volume that you have
created consists of any LDEVs (those in blue bold italics) that have been released from a different
LUSE volume, your LUSE volume can only be reset to the state it was in when the constituting LDEVs
were released from that different LUSE volume.
