Note: Make sure to correctly determine where the fc hba card and port to be tested are located.

First verify conf file is properly setup, see doc:
<Document 1608872.1> Solaris Fibre Channel (FC) Loopback Plugs and Private Loop Cables Will Not Work If "point-to-point only" Option Is Selected
Second check FC HBA port Light Tx and Rx Power Levels

Then if needed with procedure in Solution section below.
The following steps require someone physically on-site by the server/FC switch/storage. Per Oracle standard contract customer must have personnel onsite by equipment to perform basic isolation and troubleshooting and work with Oracle remote support. Basic isolation and troubleshooting will decrease time to resolve issue by determining if issue is on Oracle Server/FC HBA side or outside the Oracle Server/FC HBA perhaps in the cabling, FC Switches and/or FC Storage. Then appropriate Oracle or NON-Oracle support vendor can be engaged more quickly to address issue. Unless there are special provisions in your contract a Oracle Tech will not be dispatched to your site to perform basic isolation and troubleshooting.
