HP 3PAR OS 3.1.3 Command Line Interface Reference
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
