Port link failures on Brocade 6520 switch

  • 1.  Port link failures on Brocade 6520 switch

    Posted 05-05-2017 01:57 AM

    Hello peers,

     

    I have a strange occurence on a environment utilising Brocade 6520 switches, running FOS 7.1.3a. One 6520 per fabric. We have come to connect a new host which has two single port HBA cards. One card cabled to fabric A port 60, and the other to fabric B port 60.

     

    However, neither card is able to form a successful login into the fabric. When I issue a portshow, it shows as Offline and In_Sync. See below. This occurs on both switches. Cables and SFP's have been ruled out. Any ideas on what could be causing this issue ?

     

    Regards,

    Berd

    HI Thierry,

     

    Many thanks for that response. I'm trying to locate the release notes for 7.3.1b but can't seem to find them. Would you happen to have a link to release notes ?

     

    Thanks,

    Berd
