specific ports.
host-connected (target) ports.
disk-connected (initiator) ports.
FC ports (for Remote Copy).
Ethernet ports (for Remote Copy).
You can use additional filters to refine the data output. For complete details about statport
command options and for sample command data output, see the HP 3PAR Command Line Reference.

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. For complete details about statvlun
command options and for sample command data output, see the HP 3PAR Command Line Reference.

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 HP 3PAR 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.
You can use additional filters to refine the data output. For complete details about statvv and
statrcvv command options and for sample command data output, see the HP 3PAR Command
Line Reference.

Viewing Statistics for Data Cache Memory

To view data cache memory statistics, issue the statcmp command.
By default, data cache memory statistics are displayed by node. You can optionally display data
cache memory statistics by virtual volume by issue the statcmp -v command.
You can use additional filters to refine the data output. For complete details about statcmp
command options and for sample command data output, see to the HP 3PAR Command Line
Reference.

Viewing Statistics for CPU Usage

To view statistics for CPU usage from all nodes, issue the statcpu command.
For complete details about statcpu command options and for sample command data output,
see the HP 3PAR Command Line Reference.
