Error description

  • The CN4093 has multiple Fibre Channel Forwarders (FCFs)
internally.  If one fails or is disabled, failover may not
happen properly to the other FCF.  A CVL notification followed
by and FCF dead indication from the adapter would experience
this problem.

Problem summary


    

  • The CN4093 has multiple Fibre Channel Forwarders (FCFs)
internally.  If one fails or is disabled, failover may not
happen properly to the other FCF.  A CVL notification followed
by and FCF dead indication from the adapter would experience
this problem.

    



Problem conclusion


    

  • Pay attention to FCF Dead notifications any time we are in the
link/connection establishment phases of the adap init state
machine.  Previously we would only pay attention if we had
an actively-selected FCF, but this does not catch the CVL
followed by FCF Dead case (CVL will clear SELECTED, which was
causing us to drop the FCF Dead notification).
