HIPER (Doc Number=6969): High Impact / Highly Pervasive APARs IJ31936/IJ31191

Multiple issues seen while using NPIV adapters with AIX 7200-05 or VIOS 3.1.2

IBM has seen multiple issues using Virtual Fibre Channel (NPIV) adapters, including but not limited to:

• Path failures and timeouts
• Failure to mount Virtual Tape Libraries
• Errpt entries on boot indicating "Multiple Queues are not supported"
• Crash of AIX LPAR

There is potential for undetected data corruption with VIOS 3.1.2 and Power9, however, we have not seen it.

AFFECTED LEVELS and RECOMMENDED FIXES

1. If using NPIV on AIX 7200-05, with any level of VIOS, these fixes are recommended:

   Minimum Affected Level	Maximum Affected Level	Fixing Level	Interim Fix
   7200-05-00 devices.vdevice.IBM.vfc-client.rte 7.2.5.1	7200-05-02-2114 devices.vdevice.IBM.vfc-client.rte 7.2.5.3	7200-05-03 IJ30153 IJ30687 IJ31191 IJ31604	iFix



2. If using NPIV with VIOS 3.1.2 and Power9, this fix is recommended:

   Minimum Affected Level	Maximum Affected Level	Fixing Level	Interim Fix
   3.1.2.0 devices.vdevice.IBM.vfc-server.rte 7.2.5.0	3.1.2.21 devices.vdevice.IBM.vfc-server.rte 7.2.5.2	3.1.2.30 IJ31936	iFix

   Note: The VIOS fixes include the fix for the previously published HIPER IJ30090



3. If using NPIV on any of the below levels of AIX with VIOS 3.1.2 and Power9, this AIX fix is also recommended:

   Minimum Affected Level	Maximum Affected Level	Fixing Level
   7200-04-00 devices.vdevice.IBM.vfc-client.rte 7.2.4.0	7200-04-02-2028 devices.vdevice.IBM.vfc-client.rte 7.2.4.3	7200-04-03-2038 IJ28565
   7200-03-00 devices.vdevice.IBM.vfc-client.rte 7.2.3.0	7200-03-05-2016 devices.vdevice.IBM.vfc-client.rte 7.2.3.18	7200-03-06-2038 IJ28596
   7100-05-00 devices.vdevice.IBM.vfc-client.rte 7.1.5.0	7100-05-06-2028 devices.vdevice.IBM.vfc-client.rte 7.1.5.36	7100-05-07-2037 IJ28592

The tables above describe which active levels are affected and where to obtain fixes.
Prior to the APAR Fix being available, an Interim Fix (iFix) is available for each affected level.
The available iFixes may only apply to the latest Service Packs. If a custom iFix is required please contact IBM Support.
The iFixes can be downloaded from the same location using ftp, http, or https.
