Hello,
I'am trying to restore a mksysb-Image from a 9110-51A to a 8234-EMA with AIX 5.3.0.0 TL 07.
The mksysb was created on filesystem, after that defined in my NIM Server.
All seems to work proper.
8234-EMA gets Bootimage via tftp and the restore of the mksysb starts working.
But then it stopped with
0516-404 allocp Error
and two Options:
1 Continue
2 Perform Systems Management and then return

I choosed 2 and saw in Maintenance that the rootvg contains only one Volume hdisk0.
The second Disk wasn't assigned, though the mksysb was created with mirrored rootvg.

After extending the missing disk to the rootvg with
extendvg -f rootvg hdisk1
and
exit from the Systems Management the process worked on.

Why did this happened?

In my bosinst_data the overwrite Parameter is checked!

Cheers,
ku

Hi ku,

yes, this is a problem of mksysb recovery process,
because your rootvg is mirrored in two disks.
The mksysb needs as many disks had when it was done.
But you can change this behavior:
Create a new image.data file with only one mirror copy
of every filesystem in rootvg and only one disk.
Create a new bosinst.data with only one disk.
Create NIM resources for both files and allocate them to NIM client.
Then proceed to recover mksysb by NIM.

There is an old software "sysback" (now TSM System backup)
that let you do some changes during recovery.

Regards.
Silvia.

Hello Silvia,
thanks for your answer.
There are two hdisk in the target System.
The mksysb was taken on a mirrored System.
Why does NIM installation Process behave strange and works with only one hdisk (instead of two, which are available)?

I know sysback, but actually we have no License (sadly). I missing this "old" Tool.

Hi,

until the beginning of the recovery, NIM process is controlled by the bosinst.data.
Later, when the mksysb recovery initiates, the process first reads the image.data
for logical volumes and filesystems creation, and if it has two mirror copys
it detects later that there is not enought space.

Hello Silvia,
thanx for the clarification.
It worked like a charm with an unmirrored rootvg-mksysb.
