Never say never....AIX 5.3 on POWER8.I NEVER thought this would happen! But, “NEVER SAY NEVER!”. IBM just announced that AIX 5.3 can now run on POWER8.
As you’d expect, there are some caveats!
A special PTF (U86665.bff) provides POWER8 support on AIX 5.3 with the following limitations:
The only supported AIX 5.3 POWER8 installation methods are:
All POWER8 systems are supported with the following restrictions:
Other restrictions:
I tested this in my lab and it all worked as expected. I installed the PTF on an existing AIX 5.3 LPAR on a POWER7 750 and rebooted the partition.

My POWER8 system was an S824 running the latest firmware (840_056), with VIOS running the latest code (2.2.4.10) and the latest HMC code (8.4).

On my NIM master I created a new lppsource and SPOT for AIX 5.3 TL12 SP9 and included the required PTF U86665.
# lsnim -t spot | grep 53 spot
# lsnim -t lpp_source | grep 53 AIX5
# nim -o showres spotAIX53TL12SP9 | grep bos.mp64 bos.
# nim -o showres AIX53TL12SP9_P8 | grep bos.mp64 bos. bos. bos.
I took a mksysb on the 5.3 LPAR to my NIM master. I then used the mksysb to perform an NIM mksysb install (restore) to a new partition on the S824. This worked flawlessly. The partition was configured in POWER6 mode with SMT2 only.

The example above shows you how to migrate an AIX 5.3 system using NIM and mksysb. But you don’t have to do this, as LPM is fully supported. The migration effort for many customers is as easy as kicking off an LPM operation to move their (updated) AIX 5.3 partitions from their older Power servers to POWER8. Easy!
So I guess customers that still need to run AIX 5.3 on POWER8 now have an alternative to AIX 5.3 Versioned WPARs. But please keep in mind the performance and support considerations when making your decision. Additional README information available here: http |

Hi Charin, I don't believe this ever going to work. 4k drives are not supported with AIX 5.3. "AIX for 4k drives: AIX 7.2 TL0, or later; AIX 7.1 TL3 SP3, or later; or AIX 7.1 TL4, or later; AIX 6.1 TL 9 SP 3, or later". Please refer to the following link: http://www-01.ibm.com/common/ssi/cgi-bin/ssialias?infotype=an&subtype=ca&appname=gpateam&supplier=872&letternum=ENUSAG16-0040

Thank you very much Mr.cggibbo for your quick response.
So,
As of now, We would like to fix issue while performed install native
AIX 5.3 getting the target disk shown the zero byte size.
Thanks.
Hi Charin, could be this problem? https://www.ibm.com/developerworks/community/blogs/cgaix/entry/AIX_JFS_file_systems_and_4k_disks?lang=en
Hi,
I
have customer create issue via Salesforce to support problem : Install
AIX 5.3 native OS on Power 8 Server getting hdisk having 0 (Zero) byte
size on target disk to install.
The action taken:
We completely for:
- LPAR must be at AIX 5.3 TL12 SP9 (latest 5.3 release)+A special PTF (U86665.bff)
- FW and VIOS version passed.
But, While performed step to install native AIX 5.3 on power8 shown the hdisk target having 0 byte size.
and suspect for : POWER8 5.3 LPARs are not supported with virtual 4K block size disks
My questions are:
1. Do anyone know about the hdisk have 0 byte size.
2. Could anyone can explain about "POWER8 5.3 LPARs are not supported with virtual 4K block size disks"
Thanks.

Yes,
I
set the processor to power6 mode. Assigned 1 LV & 1 raw volume to
the LPAR. While booting the lpar from nim and check the disk.value in
installation option menu it shows 0 MB.(both disk).
Cheers,
Ram
OK. Interesting. Send me some screenshots or output, if you can. Email: cg@gibsonnet.net
my server details:
System Model: IBM,8286-41A
Platform Firmware level: SV840_104
Firmware Version: IBM,FW840.20 (SV840_104)
Since
i don't have HMC, Created the partition using IVM, I couldn't able to
set the mode to "Processor Implementation Mode: POWER 6". by default its
taking as P7. SO during installation its not identifying my virtual or
physical drive attached to it and it shows 0 MB size for both my disk .
please let me know how to to over come this issue.
Cheers,
Ram
Have you tried this?

Hello Chris my coworker sent you a twitter, about it, could you help with that ?
Hello Chris, we contract the extended support for AIX 5.3 but IBM don't share the PTF,, Could you help me with that, sharing this PTF because we have today a migration from Power 7 to Power 8 in a customer here in Perú I'll appreciate so much
