Can I get someone's thoughts on our Brocade Switch?

    We have an IBM Blade Center with two 20 port brocade switches in it that connect to another fiber switch and then

    a NetApp SAN. We have had issues with our Linux boxes dropping connections to the SAN intermittently. I reset all

    of the counters about 6 hours ago and have the following:

    The blade occbdbn5 fiber adapter card has been replaced.

    And why would an empty slot be logging errors?

    Any thoughts would be appreciated.

    so have you got this crc_g_eof before replacing the hba or after?
    errors in the empty slot makes me think that this slot sees some noise.
    i heard that some customers pushed ibm up to replacing the chassis midplane, and only this step finally helped to fix all the issues...
