AIX and PowerHA levels

Research shows these dates for AIX:
It’s generally 26 weeks, plus or minus, from the initial YYWW date. Once a TLSP APARs releases, the YYWW code is be updated.

  • 7300-01-01-2246 2022-12-02 (Next 2023Q2)
  • 7200-05-05-2246 2022-12-02 (Next 2023Q2)
  • 7100-05-10-2220 2022-09-09 (Next 2023Q1)
  • 6100-09-12-1846 2018-11-16 (EoL CSP)

My AIX selection process would be:

  • AIX from 2022 week 46 is what I have in my repo.  Another TL should be coming out 2023 Q1.  None of my customers run this, but you want this for POWER10.  NIM should be latest of all versions as well.
  • AIX from 2022 week 46 is what I have in my repo.  Another TL should be coming out 2023 Q1.  You probably want this for POWER7 and up.
  • AIX from 2022 week 20 is what I have in my repo.  I think the CSP is 2023Q1.  Supports AIX 5.2 and 5.3 WPARs.  Not much other reason to use this now other than some specific apps that are OK with OpenSSL, OpenSSH, and Java updates, but not kernel updates.
  • AIX is where I stopped tracking.  No real need for AIX 6 anywhere.  Either you’re stuck on 5.3, or you came up to 7.1 (or ideally 7.2). was needed for application compatibility on POWER9.
  • For anything POWER6 or older should really upgrade to p710 to p740 or s81x/s82x as replacements (cost).  POWER8 is EoS 2024-10-31.  POWER7 is EoS 2019.
  • AIX + U866665 on POWER8 is end-stage.  AIX 5.3 was EoS in 2012, but some people still run it now.  Power8 is EoS 2024-10-31.  Power7 was 2019.
  • AIX 5.3 PTF U866665.bff (bos.mp64. enables POWER8. AIX must be Must be patched before moving to p8. p8 must be 840 firmware or later. VIO must be or later.  Migration is by LPM, NIM, or mksysb.  equires active extended support agreement AIX p8 systems on file to download.
  • AIX older – You should not be running anything older.  AIX 5.1 was all CHRP, and AIX 4.x was all PCI.  AIX 3.x was MicroChannel.  AIX 2.1 had some PS/2 systems.  Outside of a museum, on an isolated network (or no network because CYLONS!), just have this recycled.

My PowerHA (HA/CMP) selection process would be: 

  • 7.2.7 Base is what I last grabbed.  OK for AIX 7.1.5, 7.2.5, 7.3.0 and later patch levels.
  • 7.1.3 SP09 was the end-stage for this.  OK for AIX,,, and later patch levels.  No AIX 5, and no AIX 7.3.
  • 6.1 SP15 was end-stage for this, and supported AIX 5.3.9,, 7.1.0, and later patch levels.  No AIX 5.1, 7.2, or 7.3.

UPDATE 2023-03-07:

  • Refreshed all of the info above to current.  If you’re on AIX 5.2, HA/CMP 5.x, or VIO 1.x, that’s really disappointing.
  • VIO should be  Always go current whenever possible.  If not, is your target.  If you have any VIO 1.x, upgrade.  Period.
  • System firmware, adapter microcode, disk microcode, tape microcode, and library firmware should all be latest available.
  • Storage array firmware should be latest LTS patch level, excluding any .0 versions.  I still don’t trust Data Reduction Pools.
  • ADSM/ITSM/TSM/Spectrum Protect/Storage Protect – These should typically be the final version supporting your OS/App combo.  I’m sweet on 8.1.17, though there are still major issues with deduplication pools when your database is over 3TB.  Containers and extents cannot be purged.  I have not seen SP 9.1, but I assume it will be extremely similar to SP 8.1.18 other than some minor rebadging.  Not sure.  I got dropped from the beta program because I didn’t have cycles to test their new code, and they didn’t have any interest in steering features.  They pick what they want to pick, and you’ll like it. 
  • IBM is phasing out Spectrum Protect Plus (Catalogic DPX), but might still be keeping Catalogic ECX (Copy Data Management).  In Storage Defender, IBM has picked up Cohesity DataProtect because of the cloud / DRaaS bits.  These all integrate with DS8000/Flash Systems for data immutability / vaulting / ransomware protection, and they want you to buy Rapid7 for the AI/Logic behind it.  I know regular ISP’s operations center anomaly detection us unusable due to its lack of adaptability/logic.  It just says everything is alerted every week when you run weekly fulls, etc.

I don’t really track IBMi OS (OS400), zOS, zVM, etc.  Storage should be rebranding this year though, but still no NFS/CIFS hardware.  At best, IBM sells a GPFS cluster with Ceph and with some StorWize FS7200s.
