Thanks Mark. I think I understand (I am really a z/OS person). Since my first post I did manage to IPL a cloned system: I booted up with kernel parameter "root=/dev/mapper/360050768018f030ee00000000000004c_part2" to override "root=/dev/mapper/360050768018f030ee00000000000004b_part2". Then I was able to put the new UUID into the zipl.conf and fstab files and it seemed to reboot OK (after running zipl). I can see (now that I understand the problem better) that your suggestion of using alias names would make it simpler. Incidentally the installer did not create /etc/multipath.conf. Is this something that we have to create if we want any non-standard definitions ? . Keith Gooding

Yes, but as you can tell it's going to involve more work, since the device names are going to be different for each clone you make. Perhaps the simplest method would be to use /etc/multipath.conf to create alias names for the multipath devices and use those in places such as /etc/zipl.conf, and /etc/fstab. Then, when you clone, you would need to update multipath.conf with the new "wwid" values and (probably) recreate the initrd on the clone.
