Ignite clone differ from original

KaPLis — Mon, 04 Apr 2011 07:46:45 GMT

Hi,

I want to replace root disk on a rx2660 server which does not have mirror software. Updated Ignite, made bootable tape, replaced the disk, installed hp-ux from tape.
Result: HP-UX is running, but some software that was running on it, is malfunctioning. When investigating, I found that some of the configuration files in /etc are recreated with different contents than original.
For example, /etc/rc.config.d/netconf has only lan0 still configured, other two network interfaces are still there, but commented out. Some other files were also different, like /etc/default/tz and /etc/ntp.conf.
After overwriting these files from fbackup tape, I was able to start necessary software, but in some cases it gives errors which were not there before.
From this, I assume some more files are not the same as on original system, but it's quite difficult to find where exactly.
Tape was created this way:
/opt/ignite/bin/make_tape_recovery -a /dev/rmt/0mn -AvI
Recovery was started using boot DVD (faster then tape) then installation from DVD and recovery from tape. Boot DVD was created previously on the same machine.
When installing, no changes were done to configuration, when it asked about that.
Machine RX2660
HP-UX B.11.23
Ignite C.7.12.519

What am I doing wrong, how should I restore this volume to the same configuration as original?

I know this task can be done on LVM level, but I need 100% known working backup anyway.

> -AvI

-A does not seem to work in a useful manner. The man page says that it will select disks and VGs for the selected files -- but -A by itself doesn't seem to select anything so you get perhaps a generic set of files. I never use it. The recommended way is:

make_tape_recovery -Iv -x inc_entire=vg00 -a /dev/rmt/0mn

Except for mirroring, this will fully restore your system. Here's a link about Ignite and mirroring:

Thanks,

Tried that, unfortunately -x inc_entire=vg00 did not change anything, I got the same problem. All network interfaces, except lan0, are commented out. It's not that easy to find all the differences, and I can not just restore all files from fbackup tape, since it's said no to touch system files.
Any ideas?
I have been doing this on old PA-RISC systems without any problems, now it's an Itanium.
