    Anyone else using Dell force10 network switches in their AIX environment? Specifically connecting AIX hosts to S4820T switches. I have cases open with Dell and IBM with no results so far. This is probably a hardware issue, but we are only seeing this in our AIX environment. The non-IBM servers do not have this issue.

     

    I have a couple AIX servers which do not consistently get link lights on Dell S4820T switches. We have done all the usual steps: checked speed/duplex, swapped cables, swapped servers, swapped switches, all with no result.

     

    We suspect it's a negotiation issue, just not sure if it's on the switch or NIC. That said, do IBM 1Gb NICs do something different during speed negotiation than the rest of the world?
