First step is to setup a specific IP address on every port used for ISCSI, you can do it directly into web interface in the section, if possible do not use the first port used for administration: Settings –> Network –> Ethernet Ports
For better performances you can specify a different MTU to improve performances. If you use admin port, do not change MTU, you will not be able to connect again to storage. When changing MTU, you have to change it on the target server too on the dedicated ISCSI ports, and be sure that your switch (if no direct connection) allows MTU with such value.

An invocation example to set an MTU of 1600 on port #2 in I/O group 0. All port 1 in the IOgroup will be changed (on each cluster node)
SVC> cfgportip –mtu 9000 -iogrp 0 2
To bring port 2 back to default MTU (1500)
SVC> cfgportip –defaultmtu -iogrp 0 2
On v7000 web interface (Settings –> Network –> ISCSI) you 'll see iSCSI Name(IQN), the unique identifier for on ISCSI Network required on the host Ex:
