Our NIM system becomes unresponsive while working. Look like first time that the root disk was missing. I cannot use many commands like lspv, lspath, ... ssh and other services are not operating.
I have rebooted the machine, and I can boot it to AIX, but it's an older AIX version 6.1 and not the current one 7.1
I also see that the OS is booted from hdisk0, while the current OS is booted from hdisk9. But now hdisk9 belongs to altinst_rootvg and varied off.
Look like the boot volume on hdisk9 was corrupted and system turns to the old one on hdisk0 to boot from it.
How can we re-create the boot volume on hdisk9? I tried to boot the system to single user mode on hdisk0 (old OS version), and try the bosboot command on hdisk9, but not success. It says the hd5 is already available in use.
I tried to use synclvodm and it changed my LVs on altinst_rootvg to new ones. Not sure that it just only renames the LV name, I hope it not overwrite the data on the altinst_rootvg.
Now I'm downloading the ISO file and can boot into maintenance mode. Can we do the followings:
rename all the LVs to its original name
recreate the hd5 volume
rewrite the boot volume info with bosboot and reboot the system to boot from it.
The thing I'm not very clear is, what is altinst_rootvg? If I can create the boot volume and rename the LV successfully as above, I can boot from it?
With my research about altinst_rootvg, it's a technique to replicate the current OS, this is done by backup purpose. Still reading it for more info ...
Is it necessary to put system into single user mode for applying aix 5.3 TL8 on a aix 5.3.5.0 system ?
Is the TL8 installation not totally safe ?
