Am trying to upgrade the AIX 6.1 TL 7 to TL 8. My rootvg is mirrored so i have unmirrored and taken out the secondary disk and trying to install the update via smitty alt_clone.
The filesets has been installed and finally when making the updated disk as bootable bosboot is failing. Please help me ...
Code:

bos.aso 6.1.8.16 USR APPLY SUCCESS
bos.aso 6.1.8.16 ROOT APPLY SUCCESS
bos.aso 6.1.8.16 USR COMMIT SUCCESS

... and then pulled it, then hdisk1 is empty if the reducevg completes.
It seems counter intuitive, but assuming that the two disks were completely mirrored and bootable, you would have been safer to shutdown, pull the disk, boot. That way, if you need to, you could have forced the boot via SMS to start from the disk you pulled out.
If hd5 is not on hdisk0, this would suggest that it was only on hdisk1. The unmirror will not move LVs that are not mirrored. This would mean that you could not take hdisk1 out the VG of course, so that would suggest that something was wrong at that point.
Before we panic too much. Are you happy that you have recent mksysb media to recover with?
I suggest you do an "alt-disk-install" - which would be a fresh install of the new version of the OS - or an "alt-disk-migration", which means:
- breaking the mirror of a mirrored rootvg
- update the OS on the broken-off mirror
- restart the system (from the newly updated disk)
- resynchronize by remirroring using the disk with the old OS version
alt-disk-installation is quite similar, just instead of an update a fresh install is done.
Fortunately all this is done by the procedure itself, you do not do (manually) any of these steps. I just wrote it so you can picture what goes on during the procedure.
Put the disk back in, establish the mirror again and then start over doing an alt-disk-migration. For a procedure for performing an alternate disk migration read the IBM infocenter page.

I would like to make a point here, for Alt_Disk_Install, he actually needs a empty and free disk.
You don't have to place the disk back and mirror.
Before we do Alt_Disk_Install, we actually try to break the mirror and then use that empty disk to clone the OS. It is a backup copy of the current OS
After you done you can either upgrade this or alt_disk image.
But if you want to take a backup of existing image and upgrade the binaries at the same time you use alt_disk_clone.
Your current disk will server as backup disk (it will stay at current version even after reboot) and other empty disk you use for alt_disk_clone operation will be upgraded to the new desired OS version. In both cases you just have to change the bootlist to jump different version (ofcourse after a reboot).

You are right and i should have clarified what i mean: my suggestion was to do an alternate disk migration, which needs the mirrored disk in place. It will break up the mirror as described in the process, but the procedure does that itself, you don't have to provide the broke-up mirror yourself.

Hi guys
I have joined a new department and one of my tasks is to investigate the feasibility of upgrading our current AIX v 4.3 to V5.3.
I do not know anything about AIX and any actual work will be done by an outside consultant until such time as I have built up my own knowledge.
