You can use the command-line interface (CLI) to check the status of the fibre-channel ports.
svcinfo lsnode -delim : nodename
where nodename is the name of the node whose ports you want to check.The following output shows what is displayed when you issue the svcinfo lsnode -delim : nodename command:
id:1 name:node1 UPS_serial_number:10L3ANP WWNN:5005676801000013 status:online IO group id:0 IO group name:io_grp0 partner node id:2 partner node name:node2 config node:yes UPS_unique_id:202378101C0D17A0 port id:5005676801100013 port status:active port id:5005676801200013 port status:active port id:5005676801300013 port status:active port id:5005676801400013 port status:active
The previous example shows information for the named node on line two. You can see the port ID and the status of the port in the last eight lines of the example. In this example, the last eight lines show a port status of active. You might also see the following statuses: not installed, failed, or inactive.
