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
