Does anybody out there have a 3466 NSM. If so can you please help. I am in
the process of implementing ADSM using a NSM and need to understand the
implications of a bare metal restore on this system. The 3466 Start-up guide
mentions the usual following solution :-

1. Run 'endadsm' to stop ADSM
2. Run 'prebackup' script. This unmounts all ADSM filesystems and exports
the ADSMVG
3. Run AIX 'mksysb' command to backup the ROOTVG.

and that's it.

What I'm not happy about is the fact that this is not securing the ADSMVG
which would also be needed if I ever had to perform a bare metal restore.
The problem is that the ADSMVG is 132GB and all I have is a single 4mm DAT
drive with 2GB tape capacity, therefore I'm not even sure if this is
feasible. I have even read back the contents of the 'mksysb' tape and all I
can see (as expected) was the rootvg files.

If I was to perform this process then this would have to be performed using
AIX 'savevg adsmvg' command.

Can any body confirm whether I am worrying in vane or do I need to perform
this process to ensure that I can rebuild my system from scratch. Many
thanks for your time in advance.
