I'm running AIX 4.1.4 with ADSM HSM

I had to replace a defective hdisk0 some weeks ago. I'm not sure if I did
something wrong.
I had a current mksysb -i /dev/rmt0

I booted from the mksysb, and the system came up properly, but as it
seems, the restored system only had the rootvg information in the ODM.
I had to manually importvg every of the 57 filesystems, taking care that
every filesystem sits on the correct original /dev/lv??.

Also the system lost some configuration data, like default route and
default network interface.

Did I miss something, when making the mksysb ?

I suspected this behaviour, so I'm also writing some data onto the rootvg
to the backuped tape, like lsfs, lslv -l LogicalVolume, to make sure to be
able to import the volumegroups.

I do NOT know, if this happens to every AIX 4.1.4, but this happened to
me, and it was a really hard day ... :-((

Anyone has an idea, how to improve this procedure?

Thank you

Nice idea :-)
