3.5 Host Interface Management > show host-lu-qos-performance
V:
Maximum number of I/Os per second for a LUN
W:
Average transfer amount per second for a LUN (in MB/s)
X:
Minimum transfer amount per second for a LUN (in MB/s)
Y:
Maximum transfer amount per second for a LUN (in MB/s)
Z:
Accumulated delay time since the start of a command from the QoS control of a LUN (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.
a:
Average delay time for a single command from the QoS control of a LUN (in milliseconds)
When the port type that is described above is iSCSI and a host without an IP address is specified,
performance measurement information is obtained from multiple IP address. When an IP address is not
specified, "J: Host IP address" shows the actual IP address of the host that is logged in to the ETERNUS Disk
storage system.

Example(s)
The following example displays the performance measurement information when no parameters are set. For
CM#1 CA#0 Port#0, Delay Total Time exceeds the limit and "Overflow" is displayed:
CLI> show host-lu-qos-performance
Port
CM#0 CA#0 Port#0
CM#0 CA#0 Port#1
CM#1 CA#0 Port#0
The following example displays the performance measurement information when a host interface port with
the host affinity mode enabled is set:
CLI> show host-lu-qos-performance -port 000
