Assuming you have not configured that specific port as an L-Port, this can happen where the HBA did not completely log on to the fabric. This issue has been known to happen on Emulex HBAs.

To resolve, simply disable and re-enable the port on the SAN switch:

portdisable <port-number>
portenable <port-number>
