Port stuck in G-port on DCX

  • 1.  Port stuck in G-port on DCX

    Posted 02-19-2014 11:41 PM

    Hello,

     

    We're having problems with a new installation of AIX servers with Emulex 8Gbit HBAs.

    The ports on both fabrics get stuck on G-port mode.

    We're running v7.0.2c on our switches.

     

    fabriclog -s:

    I've disabled / enabled the port and ran portcfgdefault on it, but no help. Also tried manually setting different speeds but the result is the same.

     

    Any ideas what might cause this?

    The issue is HBA side.

     

    I made the same by a customer exactely One year.

     

    I believe with "lscfg -sintax" command on AIX Host, you should get how the HBA is configured

    the output show HBA information only, and not how is configured it.

     

    you must made change in the HBA topology, in order to get the port working with DCX port.

    Update the firmware on the HBA to the latest supported release and also include the driver for AIX.

     

    Also see here. > http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=migr-5087103

     

    The problem is that the HBA does not respond to the ELP (Exchange Link Parameters) request from the switch.

     

    The HBA side needs to get fixed.
