HP 3PAR Command Line Interface Reference (OS 3.1.2 MU2) (QL226-97016, June 2013)

Specifies that statistics for only nonidle devices are displayed. This option is shorthand for the
option filt curs,t,iops,0.
SPECIFIERS
<VV_name|pattern>...
Only statistics are displayed for the specified VV or pattern. Multiple volumes or patterns can be
repeated (for example <VV_name> <VV_name>...). If not specified, all VVs are listed.
RESTRICTIONS
None.
EXAMPLES
The following example displays I/O statistics for all VVs:
cli% statvv -iter 1
15:31:21 05/31/07 r/w I/O per second KBytes per sec Svt ms IOSz KB
VVname Cur Avg Max Cur Avg Max Cur Avg Cur Avg Qlen
admin t 0 0 0 0 0 0 0.0 0.0 0.0 0.0 0
test2 t 0 0 0 0 0 0 0.0 0.0 0.0 0.0 0
------------------------------------------------------------------------
total t 0 0 0 0 0.0 0.0 0.0 0.0 0
The columns in the example above are identified as follows:
VVname. The virtual volume name.
r/w. The I/O type. Values can be read (r), write (w), or read and write (t).
I/O per second Cur. The current number of I/O per second.
I/O per second Avg. The average number of I/O per second.
KBytes per Max. The maximum number of KB per second.
KBytes per Cur. The current number of KB per second.
KBytes per Avg. The average number of KB per second.
Svt ms Max. The maximum service time in milliseconds.
Svt ms Cur. The current service time in milliseconds.
Svt ms Avg. The average service time in milliseconds.
IOSz KB Cur. The current I/O size in KB.
IOSz KB Avg. The average I/O size in KB.
Qlen. The queue length.
NOTES
If a <VV_name> or <pattern> are specified, then VVs with names matching any of the
patterns are listed. Otherwise all VVs are listed. These patterns are glob-style patterns. Refer
to “Glob-Style Pattern” (page 12) for further information.
VVs may be accessed externally by hosts and internally by the prefetcher. VV data measured
by this command include accesses by the prefetcher.
In addition to external accesses by hosts, VVs may be read internally by the system read-ahead
prefetcher. The histvv data includes read-ahead accesses from the prefetcher, which can
