Table 47 VV Space Report Metrics (continued) Metric Description Snap Rsvd Space 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 Vcopy 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 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 Used Space Admin (snapshot metadata) space that is used by the selected VVs. This is zero for Virtual Copy (snapshot) VVs. Admin Free Space Admin Rsvd Space that is not actually used. This is zero for Virtual Copy (snapshot) VVs. Admin Rsvd 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 Vcopy 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 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 Vcopy Space 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 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 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 Rsvd 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. Virtual Size Virtual size of the selected VVs. Performance Reports This section describes the metrics for reports that provide performance data for a given system. Common Performance Metrics Table 48 (page 109) describes the metrics that are shown in common for (PD, Port, LD and VLUN) performance reports when selecting the Versus TIme and At TIme report types.
