Error description
The AIX Fibre Channel driver can lose access to the SAN fabric directory server after a link event. The problem will only occur with Emulex-family adapters which have dynamic tracking or fast fail enabled (i.e. fscsi attribute dyntrk=yes or fc_err_recov=fast_fail). The problem will only occur when attached to a SAN switch. It is sensitive to the switch behavior so will only occur with certain switches.
