IJ10371: POSSIBLE ERRORS IN CERTAIN NETWORK ADAPTERS APPLIES TO AIX 7200-02

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• **************************************************************
  * USERS AFFECTED:
  * Systems running the AIX 7200-02 Technology Level
  * with
  * devices.ethernet.lnc2.rte below the 7.2.2.17 level
  * or
  * devices.ethernet.lnc.rte below the 7.2.2.17 level.
    **************************************************************
  * ERROR DESCRIPTION:
  * Network adapters using the 'lncentdd' and 'lnc2entdd'
  * drivers may experience issues due to unintended flash writes
  * during the adapter port open/close operations.
  * Affected network adapters currently include the following
  * Feature Codes:
  * EN15, EN16, EN17, EN18, EN0H, EN0J, EN0M, EN0N, EN0K, EN0L.
  *
  * These issues have been primarily seen when the adapter has
  * some unused ports with no IP address configured on them,
  * and performance/health monitoring tools repeatedly open and
  * close those unused ports.
  *
  * We have seen the following issues occur:
  * - HW_TMP_ERR for the affected adapters seen in the errlog
  * - adapter ports get into a dead state, and remain unusable
  *   until partition reboot
  * - adapter permanently failing to configure, requiring
  *   adapter replacement
  *
  * Find out if a system has any adapters using an affected
  * driver with lsdev, for example:
  *
  * # lsdev -F "name ddins" | grep -e lncentdd -e lnc2entdd
  *
  * Note: on a VIOS, this must be run as root using
  * 'oem_setup_env'.
  *
  * As a workaround before applying the fix, a 'dummy' IP
  * address can be configured on the unused ports.  This will
  * prevent the frequent open/closes of the adapter ports
  * monitoring tools.
    **************************************************************
  * RECOMMENDATION:
  * Install APAR IJ10371.
  * Prior to fix availability, an interim fix is available from
  * either
  * ftp://aix.software.ibm.com/aix/ifixes/ij10371/
  * https://aix.software.ibm.com/aix/ifixes/ij10371/
  * Installation of the ifix requires a reboot.
