Admin (snapshot metadata) space that is used by the selected VVs. This is zero for Virtual
Copy (snapshot) VVs.
Admin Used Space
Admin Rsvd Space that is not actually used. This is zero for Virtual Copy (snapshot) VVs.
Admin Free Space
Space that is reserved for Admin Space for the selected VVs (Admin Used Space + Admin
Free Space). This is zero for Virtual Copy (snapshot) VVs.
Admin Rsvd Space
Admin Space used by Virtual Copy (snapshot) VVs only. This is zero for all VVs that are not
Virtual Copies (snapshots). Note that this value is calculated on the HP 3PAR StoreServ Storage
Admin Vcopy Space
by running the updatesnapspace command. System Reporter does not run this command.
Beginning with the HP 3PAR OS 2.3.1 release running the updatesnapspace command
can be scheduled periodically on the system.
Total (Snap + Admin) Vcopy space used by Virtual Copy (snapshot) VVs only. This is zero
for all VVs that are not Virtual Copies (snapshots). Note that this value is calculated on the
