60 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
Setting port mask by using the CLI and GUI
The command to apply a local FC port mask on CLI is chsystem -localfcportmask mask. The 
command to apply a remote FC port mask is chsystem -partnerfcportmask mask.
If you are using the GUI, click Settings → Network → Fibre Channel Ports. Then, you can 
select the use of a port. Setting none means no node-to-node and no replication traffic is 
allowed, and only host and storage traffic is allowed. Setting local means only node-to-node 
traffic is allowed, and remote means that only replication traffic is allowed. Figure 3-7 shows 
an example of setting a port mask on port 1 to “Local”.

3.7  iSCSI configuration planning
Each Storwize V7000 node is equipped with up to three onboard Ethernet network interface 
cards (NICs), which can operate at a link speed of 10 Mbps, 100 Mbps, or 1000 Mbps. All 
NICs can be used to carry iSCSI traffic. For optimal performance, use a 1 Gbps links between 
Storwize V7000 and iSCSI-attached hosts when the Storwize V7000 node’s onboard NICs 
are used.
An optional 10 Gbps 2-port Ethernet adapter is available. One such adapter can be installed 
in each node and can be used to add 10 Gb iSCSI/FCoE connectivity to the Storwize V7000.
Figure 3-8 on page 61 shows an overview of the iSCSI implementation in the Storwize 
V7000.
