[Function] This command shows statistical information collected by devices or drivers.
Statistical information includes data such as total count of I/Os after OS boot, I/O size
distribution, processing times to send/receive I/Os. This command displays statistical
information for each port, but a core id number can be specified to display and statistical
information of each core can be indicated.
[Syntax]
<Display I/O Total Counts>
hfcmgr -pm <logical-device-name> count [core] [vport { <vport number>|all} ]
<Display I/O Size Distribution >
hfcmgr -pm <logical-device-name> io [core] [vport { <vport number>|all } ]
<Display I/O Processing Time>
hfcmgr -pm <logical-device-name> latency [core] [vport { <vport number>|all }

core :
Display statistical information for each core.
vport <vport no> :
Display statistical information for each virtual fibre channel port.
For identify the id number of virtual fibre channel port, refer to
“Display General Information ". A vport number can be specified as
shown below.
When “vport all” is specified as command-line parameter, hfcmgr
displays information of “vport 0” and all configured vports. The
information displayed as “vport 0” corresponds to the result without
the command-line parameter “vport”, or the information of the
physical Fibre Channel port that contains the vport.
