In real Disaster Recovery, there's nothing to do after reload of your system
in your backup center. The problem is only to set up the correct network.
If you want to clone your system in an another LPAR and get the two
partitions online at the same time, this is what i do:
I've got two partition PROD and TEST
PROD system's is on a 3390-3 at 031E
TEST system's is on a 3390-3 at 031F
PROD parmfile's is dasd=031E,031F etc...
dasda is 031E
dasdb is 031F
- I do an OS/390 offlindr restore from backup of 031E to 031F
From Linux PROD:
- a mount of dasdb (031F) to /mnt/backup
- vi of /mnt/backup/boot/parmfile and set new value: dasd=031F instead of
dasd=031E,031F
- silo for establish the new ipltext to /dev/dasdb
- vi of /mnt/backup/etc/rc.config to set new value like ipaddres,
hostname...
- vi of /mnt/backup/etc/modules.conf to set new value like device address to
lcs, ctc...
- IPL from Linux TEST at 031F.

Can you explain how exactly to go about this, Please. I do understand it
theoretically, but can you explain the steps required for the restore
process as instructions, Please.
Thanks in Advance,
Samy Rengasamy.

We have SuSe 7.0 running successfully in an LPAR by itself. Used
offlindr - OS/390 offline DASD dump/restore program source to backup the
complete linux dasd's from MVS in 18 minutes. We are setting up another
LPAR
to restore the data to test disaster recovery. Has anybody done this
before?
We do have to change /etc/fstab and /etc/mtab. What were the challenges
faced by any of you? Any catches, snags, surprises.??
Thanks for your help,
Samy Rengasamy.
