APAR status

• Closed as program error.

Error description

• **************************************************************
  * USERS AFFECTED:
  * Systems running the AIX 7200-05-08 Technology Level
  * or VIOS 3.1.4.4x with any of the following filesets
  * at or between the given levels:
  * MIN          MAX          FILESET
  * 7.2.5.202    7.2.5.202    devices.ethernet.mlx.rte
    **************************************************************
  * ERROR DESCRIPTION:
  * Some 10GbE/40GbE RoCE adapters will not configure on the
  * following levels of AIX and VIOS:
  *
  * AIX 7200-05-08
  * AIX 7300-02-02
  * VIOS 3.1.4.40/3.1.4.41
  * VIOS 4.1.0.20/4.1.0.21
  *
  * The device driver cannot be loaded and the devices will
  * remain unusable in a "defined" state, resulting in loss of
  * network connectivity to the LPAR.  For a VIOS LPAR, this
  * can affect client LPARs with virtualized connections that
  * use this adapter as well.
  *
  * The following adapters are affected (feature code followed
  * by description):
  * EC27 PCIe2 2-Port 10GbE RoCE SFP+ Adapter LP
  * EC28 PCIe2 2-Port 10GbE RoCE SFP+ Adapter
  * EC29 PCIe2 2-Port 10GbE RoCE SR Adapter LP
  * EC30 PCIe2 2-Port 10GbE RoCE SR Adapter
  * EC37 2-PORT 10GbE EN/RoCE PCIe 3.0 LP X8 ADAPTER
  * EL3X 2-PORT 10GbE EN/RoCE PCIe 3.0 LP X8 ADAPTER
  * EC38 2-PORT 10GbE EN/RoCE PCIe 3.0 LP CAPABLE X8 ADAPTER
  * EC2M 2-PORT 10GbE EN/RoCE PCIe 3.0 LP X8 ADAPTER W/OPTICS
  * EL40 2-PORT 10GbE EN/RoCE PCIe 3.0 LP X8 ADAPTER W/OPTICS
  * EC2N 2-PORT 10GbE EN/RoCE PCIe 3.0 LP CAPABLE X8 ADAPTER
  * W/OPTICS
  * EC3A 2-PORT 40GbE RoCE SFP+ PCIe 3.0 LP ADAPTER
  * EC3B 2-PORT 40GbE RoCE SFP+ PCIe 3.0 LP CAPABLE
  * EL27 (RP #EC27) 2-PORT 10GbE RoCE SFP+ LP ADAPTER
  *
  * Use "How to determine Feature Code"
  * (https://www.ibm.com/support/pages/how-find-feature-code-
  * aix-linux-ibm-i-adapters-and-going-fix-central-look-fixes)
  * to help determine if you have an affected adapter.
  *
  * Prior to updating to one of the levels above, if the
  * affected adapters are used, care must be taken to apply an
  * ifix for this issue prior to booting on the updated SP or
  * else there may be no network connectivity available to the
  * LPAR after booting.
  *
  * For normal AIX updates and VIOS updateios, the ifix can be
  * applied to the LPAR after the SP is applied, before rebooting.
  * For nim installs, the ifix can be applied to the update spot
  * resource by following the steps HERE
  * (https://www.ibm.com/docs/en/aix/7.3?topic=resources-
  * installing-interim-fix-into-spot-resource).
  * For alt_disk installs, the ifix can be applied to the
  * upgraded alt_disk image by following step 3 HERE
  * (https://www.ibm.com/support/pages/managing-multiple-
  * instances-altinstrootvg-and-applying-fixes-them).
  * For viosupgrade, first upgrade to 4.1.0.10 using viosupgrade
  * (making sure the fix for HIPER IJ50326
  * (https://www.ibm.com/support/pages/node/7145269) is in place
  * first).  After completing that upgrade, then apply
  * 4.1.0.21 SP + ifix at the same time using updateios.
    **************************************************************
  * RECOMMENDATION:
  * Install APAR IJ51639.
  * Prior to fix availability, an interim fix is available from
  * either
  * ftp://aix.software.ibm.com/aix/ifixes/ij51639/
  * https://aix.software.ibm.com/aix/ifixes/ij51639/
  * The ifix can be installed using Live Update (LU).
  * If LU is not used, installation of the ifix requires a
  * reboot.
