12.2.3 Viewing VLUN Statistics
 To view VLUN statistics, issue the statvlun command.
The data output can be further refined to display only VLUN statistics from:
◆ specific domains.
◆ specific hosts.
◆ specific virtual volumes.
◆ specific LUNs.
◆ ports from specific nodes, slots, or ports.
You can use additional filters to refine the data output. Refer to the InForm OS Command
Line Reference for complete details about
statvlun command options and for sample
command data output.
12.2.4 Viewing Virtual Volume Statistics
 To view virtual volume statistics, issue the statvv command.
By default, statistics for virtual volume read and write operations are displayed together.
You can optionally display statistics for volume reads and writes separately by issuing the
statvv -rw command.
You can use additional filters to refine the data output. Refer to the InForm OS Command
Line Reference for complete details about
statvv command options and for sample
command data output.
12.2.5 Viewing Statistics for Data Cache Memory
 To view data cache memory statistics, issue the statcmp command.
NOTE: Virtual volumes may be accessed externally by hosts and internally by the
system prefetcher. When viewing virtual volume I/O statistics, the information
provided by the InForm CLI includes access by the prefetcher. To see only external
I/O statistics, view the VLUN statistics for a specific virtual volume/host
combination.
