Creating a Virtual Volume Space Report
The Virtual Volume Space report displays physical disk space for virtual volumes according to
usage type. Each usage type is shown in a different color on the same chart. The X-axis (category)
represents time, and the Y-axis (value) indicates the amount of disk space.
A table below the chart lists the following values:
Description Column
The date and time usage information was collected. (Shown only for values over time chart
types.) Time
Raw physical disk space reserved for User (base volume) Space for the selected virtual volumes.
This is zero for Virtual Copy (snapshot) virtual volumes. User Raw Rsvd
Raw physical disk space reserved for Snap (snapshot copy) Space for the selected VVs. This
is zero for Virtual Copy (snapshot) virtual volumes. Snap Raw Rsvd
Raw physical disk space reserved for Admin (snapshot metadata) Space for the selected
virtual volumes. This is zero for Virtual Copy (snapshot) virtual volumes. Admin Raw Rsvd
Total (user + snap + admin) Raw physical disk space reserved for the selected VV. This is
zero for Virtual Copy (snapshot) virtual volumes. Total Raw Rsvd
User space that is used by the selected virtual volumes. For fully provisioned virtual volumes,
all the User Rsvd Space is considered used. For thin provisioned virtual volumes, only some User Used
part of the User Rsvd Space may be used (the rest is User Free Space). This is zero for Virtual
Copy (snapshot) virtual volumes.
User Rsvd Space that is not actually used. This is zero for Virtual Copy (snapshot) virtual
volumes. User Free
Space that is reserved for User (base volume) Space for the selected virtual volumes. This is
zero for Virtual Copy (snapshot) virtual volumes. User Rsvd
Snap space that is used by the selected virtual volumes. This is zero for Virtual Copy (snapshot)
virtual volumes. Snap Used
Snap Rsvd Space that is not actually used. This is zero for Virtual Copy (snapshot) virtual
volumes. Snap Free
Space that is reserved for Snap Space for the selected virtual volumes (Snap Used Space +
Snap Free Space). This is zero for Virtual Copy (snapshot) virtual volumes. Snap Rsvd
Snap Space used by Virtual Copy (snapshot) virtual volumes only. This is zero for all virtual
volumes that are not Virtual Copies (snapshots). Note that this value is calculated on the HP VCopy Snap
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 (snapshot metadata) space that is used by the selected virtual volumes. This is zero
for Virtual Copy (snapshot) virtual volumes. Admin Used
Admin Rsvd Space that is not actually used. This is zero for Virtual Copy (snapshot) virtual
volumes. Admin Free
Space that is reserved for Admin Space for the selected virtual volumes (Admin Used Space
+ Admin Free Space). This is zero for Virtual Copy (snapshot) virtual volumes. Admin Rsvd
Admin Space used by Virtual Copy (snapshot) virtual volumes only. This is zero for all VVs
that are not Virtual Copies (snapshots). Note that this value is calculated on the HP 3PAR VCopy Admin
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 virtual volumes (User Used Space + Snap Used Space +
Admin Used Space). This is zero for Virtual Copy (snapshot) virtual volumes. Total Used
