AIX

Hello team,

First, I successfully updated AIX from 7.2TL5SP7 to 7.2TL5SP9

However many questions marks subsiste.

I assigned 2 more disks for LKU,hidisk1 should contain alternative disk (clone of hdisk0) and hdisk2 to surrogate disk (mirror rootvg from hdisk0 taken to new created partition).

After success KLU, I have the alternative disk shown as lvup_rootvg as beow.

hdisk0 00ccf8a79c868f32 rootvg active

hdisk1 00ccf8a7653b8f65 lvup_rootvg

hdisk2 00ccf8a716488169 None

This disk "hdisk1" can be used to rollback ? the answer is no. 

 I changed bootlist to boot from hdisk1 but disk unbootable !!! how ? it should boot to rollback right ?

Another questions, if I have efixes to install after update, how can I proceed, making another LKU or is the anoterway to include during LKU ?

I used geninstall function during this try. ( I tried to upgrade with nim server but the upgrade was on the initial disk ??? even I put hdisk1 and hdisk2 on liveupdate.data on nim and on the lpar ???)

Thanks in advance to clarify me above questions;

Kind regards,

Houas

Thanks to Chris and Christian for your answer. I folllowed boths your documentations to test Live update. What I understood the rootvg is mirrored on mhdisk and the update happened on nhdisk (serrogate) then at the end of live update, original rootvg updated, mdisk can be used to roll back?

What I remark, on my test, the update start updating rootvg first, then clone disk on nhdisk (serrogate), the mirrorvg on mhdisk ?

Here my config

$lspv

hdisk0          00ccf8a79c868f32                    rootvg          active
hdisk1          00ccf8a7653b8f65                    None
hdisk2          00ccf8a716488169                    None
