HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

Viewing Port Statistics
• To view port statistics, issue the statport command.
By default, only statistics for data transfers are displayed. You can optionally display statistics
for control transfers or both data and control transfers by issuing the statport -ctl or
statport -both command, respectively.
Data output can be further refined to display only port statistics from:
◦ specific nodes.
◦ specific PCI slots.
◦ specific ports.
◦ host-connected (target) ports.
◦ disk-connected (initiator) ports.
◦ Fibre Channel ports (for Remote Copy).
◦ Ethernet ports (for Remote Copy).
You can use additional filters to refine the data output. Refer to the InForm OS Command Line
Reference for complete details about statport command options and for sample command
data output.
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.
Viewing Virtual Volume Statistics
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 OS CLI includes
access by the prefetcher. To see only external I/O statistics, view the VLUN statistics for a specific
virtual volume/host combination.
• To view virtual volume statistics, issue the statvv command.
• To view remote copy virtual volume statistics, issue the statrcvv 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.
