-port
Optional. This parameter specifies the port and the LUN or host that are associated with the
port for which the performance measurement information is to be displayed. Multiple ports
cannot be specified.
Example: -port 000,100
For details, refer to
"1.2.14 Host Interface Port Syntax" (page 25)
.
xyz
"x" is the controller module (CM) number, "y" is the CA number, and "z" is the port
number.
Example: "123" indicates CM#1-CA#2-Port#3
-host-number
or
-host-name
Optional. This parameter specifies the host or the LUNs that are associated with the host for
which the performance measurement information is to be displayed. The "-port" parameter
must be set to use this parameter. Multiple hosts cannot be specified. For details, refer to

A B C D E F G H I
A:
Port number
B:
Average number of I/Os per second for a port
C:
Minimum number of I/Os per second for a port
D:
Maximum number of I/Os per second for a port
E:
Average transfer amount per second for a port (in MB/s)
F:
Minimum transfer amount per second for a port (in MB/s)
G:
Maximum transfer amount per second for a port (in MB/s)
H:
Accumulated delay time for the start of a command due to the QoS control of a port (in milliseconds)
"Overflow" is displayed when a long time passes from the start of performance measurement to the end of
performance measurement and the accumulated delay time exceeds the limit.
I:
Average delay time for a single command due to the QoS control of a port (in milliseconds)
