HP StorageWorks SAN Virtualization Services Platform Manager command line interface user guide (AG781-96016, March 2009)

Description
Purges (deletes) old virtual disks, provided they all have the same root name (all start with the same
prefix, and the suffix was automatically created by the VSM API through the Template argument).
NOTE:
Virtual disks with R/W permissions set are not purged.
This command can be used for virtual disks created by snapclones. If GroupTemplateName exists
and is not empty, snapclone groups are purged based on the group root name and their creation
time. The number to keep may be zero (for example, delete all).

operation is permitted only if:
• The designated snapshot is defined on the last and only PiT of the source virtual disk or snapshot.
• There are no other snapshots/PiTs defined on the source virtual disk or snapshot.
• There are no snapshots or PiTs defined on the designated snapshot.
