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 Storage System
Snap Vcopy Space
by running the updatesnapspace command. System Reporter does not run this command.
Beginning with the InForm OS 2.3.1 release running the updatesnapspace command can
be scheduled periodically on the HP 3PAR Storage System.
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 Storage System
Admin Vcopy Space
by running the updatesnapspace command. System Reporter does not run this command.
Beginning with the InForm 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 Storage System by running the updatesnapspace command. System Reporter
does not run this command. Beginning with the InForm 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.
