I/O performance
Use the fcpim -ioperf command to display I/O performance in terms of IOPs and throughput for
physical ports and I-T nexus (ITN) sessions for a logical port. Use the command with a physical port
range or with a specific physical port ID.
Using port range
The following command displays IOPs and throughput for a range of physical ports.
--ioperf [-l | -r] [-c count] [-i interval]
where:
port_range This is the adapter number/port number-adapter number/port number. For
example, the range 1/0-2/0, includes adapter 1, port 0 and adapter 2, port
0.
-l Displays information about all logical ports in all physical ports in the range.
-r Displays information about all ITM sessions in all physical ports in the range.
This includes all logical and remote port information.
-c Count. The number of iterations of the display. The default behavior is to
continuously refresh. Use Ctrl-C to terminate.
-i Interval. The sampling delay in seconds [default is 1 second]. The sampling
interval can be between 1 and 10.
Using specific port ID
The following command displays IOPs and throughput for a specific physical port ID.
--ioperf [-l ] [-r ] [-c count] [-i interval]
where:
port_id ID of the port for which you want to display statistics. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1, you
would use 1/1 as the port identification.
-l pwwn Displays information about a specific logical port for the physical port. To
display data about all logical ports, use -l without a PWWN.
-r pwwn Displays information at I-T nexus between a given logical port and specified
remote port for the physical port. To display data about all remote ports, use
-r without a PWWN.
-c Count. The number of iterations of the display. The default behavior is to
continuously refresh. Use Ctrl-C to terminate.
-i Interval. The sampling delay in seconds [default is 1 second]. The sampling
interval can be between 1 and 10.
