HP SAN Virtualization Services Platform - Manual (Page 36)

If the LastInstance flag is used, the preceding PiT name is the root name, and the most recently
created snapshot PiT (with a template name) is used.
If the LastAsyncMirror/LastSyncMirror flag is used, the preceding PiT name is the root name,
and the most recently created asynchronous/synchronous mirror PiT on the specific virtual disk is
used. This root name is different from the asynchronous/synchronous mirror template name. You must
retrieve this root name from the list of PiTs defined on the specific virtual disk.
NOTE:
•
This command is similar to CreateSnapshot, but enables you to associate the created snapshot
to a specific LUN number on each host.
• The command is designed for a UDH (user defined host), under the intelligent switch framework.
• If the LUN number for UDH is set to -1, a LUN is associated automatically to that snapshot under
the relevant host.
If you want to give permissions to the host, but the LUN number is not important (but still assigned),
the LUN number for the host should be -1. Check the VSM user guide documentation for valid values.

Description
Creates a snapshot with LUN on the virtual disk's most recently created PiT. The PiT name is not
specified, but the PiT type can be specified.
