Error description

  • **************************************************************
    * USERS AFFECTED:
    * Systems running the AIX 7200-02 Technology Level
    * with devices.pciex.df1060e214103404.com between
    * and including the 7.2.2.0 and the 7.2.2.15
    * levels.
      **************************************************************
    * ERROR DESCRIPTION:
    * Fibre-Channel adapters utilizing the emfcdd driver could be
    * impacted if an adapter firmware upgrade is performed on
    * unused fcs instances while, at the same time, running fcstat
    * on another unused fcs instance associated with the same
    * adapter.
    *
    * Other performance or health related processes may also
    * trigger this if they also open unused fcs instances
    * similarly to fcstat.
    *
    * The firmware update could fail or in some cases the adapter
    * firmware may become faulty where the physical adapter is no
    * longer usable.
    *
    * This problem has not been observed if all fcs instances
    * associated with the physical adapter are in-use during the
    * adapter firmware upgrade.
    *
    * Find out if a system has any adapters using an affected
    * driver with lsdev, for example:
    *
    * # lsdev -F "name ddins" | grep emfcdd
    *
    * Note: on a VIOS, this must be run as root using
    * 'oem_setup_env'.
      **************************************************************
    * RECOMMENDATION:
    * Install APAR IJ09176.
    * Prior to fix availability, an interim fix is available from
    * either
    * ftp://aix.software.ibm.com/aix/ifixes/ij09176/
    * https://aix.software.ibm.com/aix/ifixes/ij09176/
    * Installation of the ifix requires a reboot.
      **************************************************************
    

Local fix

  • 1) retry adapter microcode upgrade
    or
    2) perform microcode upgrade on actively used fcs
    instances
    or
    3) stop monitoring applications from polling the adapter
    or
    4) If all adapters fcs instances are unused, place
    protocol driver associated with
       the firmware upgrade in a defined state with the
    following command:
    
    Example: Assuming your upgrading firmware on fcs0
    rmdev -Rl fscsi0
    
    The above will place fscsi0 in a defined state
    

Problem summary

  • Adapter microcode update might fail with FCA_ERR6 and sense
    code 518
    

Problem conclusion

  • code modified to return error to the open thread, if adapter
    microcode update is already in progress
    

Temporary fix
