Hi all,
I'm trying to restore a mksysb tape but something goes wrong.

I followed the document "IBM Backing Up the Operating System in AIX 4
and 5" to make a mksysb tape image of an AIX 5.2 (oslevel -r says:
5200-04) installed on a 7025 F50.
When i try to use it to install another 7025 F50, everything goes
right till the "Over mounting /." message appears.
After a while I see lots of errors about "Symbol resolution failed for
/usr/ccs/lib/libc.a(shr.o) ...".

I left it running that way for about 12 hours and nothing changed, so
I rebooted and AIX was unable to start.
The only thing that worked was to make an overwrite installation from
aix cds...

Help!

Greetings,
Francesco.

That type message usually indicates you booted from an AIX version
with maintenance level lower than the mksysb image. Did you boot from
the AIX base media CD, and then select "install from system backup"?
If the base media CD was at ML01 and your image is at ML04, you'll see
that message.

See pTechnote0249

# After the mksysb data has been restored at about 84% overmouting /
will be displayed. If you have booted from base media that is not the
same AIX level or maintenance level as the mksysb you could get errors
similar to the following:

Examine .loader section symbols with the 'dump -Tv' command.
Could not load program /usr/bin/sh:
Symbol resolution failed for /usr/ccs/lib/libc.a(shr.o) because:
Symbol
getvtid (number 258) is not exported from dependent module /unix.
INIT: SINGLE USER MODE
To correct this boot from base media that has a maint level the same
or
higher as the version of the mksysb tape and re-do the clone.

Yes.

Ok. I think this is what I did.

On a separate note - this is a really annoying feature of AIX 5.2. Most
people only have the AIX media that ships with the machine. As a maintenance
level comes out - that renders the AIX CD's useless as you then can't
restore your mksysb to the same machine! Yes, you can around it by creating
a boot CD but I bet a lot of people will get caught out with this one!

AIX media gets refreshed, typically when a new ML gets releases. If you
have a paid up software subscription or the newer AIX maintenance fee
paid up, you are entitled to get refreshed media at no charge.

Didn't now that! I will consult with the IBM sales guy. Funny how he never
mentioned this... ;-)
