HP 3PAR StoreServ 7000 Storage - Manual (Page 109)

Table 47 VV Space Report Metrics (continued)
Description Metric
Space that is reserved for Snap Space for the selected VVs (Snap Used Space + Snap Free
Space). This is zero for Virtual Copy (snapshot) VVs. Snap Rsvd Space
Snap 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 Snap 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 HP 3PAR StoreServ Storage.
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 Total Vcopy Space
HP 3PAR StoreServ Storage 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 used space for the selected VVs (User Used Space + Snap Used Space + Admin Used
Space). This is zero for Virtual Copy (snapshot) VVs. Total Used Space
Total reserved space for the selected VVs (User Rsvd Space + Snap Rsvd Space + Admin
Rsvd Space). This is zero for Virtual Copy (snapshot) VVs. Total Rsvd Space
Virtual size of the selected VVs. Virtual Size
