It's probably using UUID and not the 0200 address
Here's the things I had to do to allow clones and allow it to run in other
places after a flashcopy.
1. Added root=/dev/disk/by-path/ccw-0.0.0101-part1 to the kernel parms (under
yast2, system, bootloader) (101 is our IPL address)
2. In /etc/default/grub
GRUB_DISABLE_LINUX_UUID=true
GRUB_CMDLINE_LINUX_DEFAULT="root=/dev/disk/by-path/ccw-0.0.0101-part1
hvc_iucv=8 TERM=dumb crashkernel=103M vmhalt=LOGOFF vmpoff=LOGOFF"
SUSE_REMOVE_LINUX_ROOT_PARAM=true
And then run grub2-mkconfig -o /boot/grub2/grub.cfg
3. echo 'persistent_policy=by-path' >> /etc/dracut.conf
grub2-install
dracut -f
This was on SLES 12 SP2. We didn't attempt SP1.

Subject: [LINUX-390] SLES12 boot error after clone
A bootable SLES12 SP1 system was cloned using flashcopy.
All minidisks on the clone are the same virtual address.
At boot on the clone we get:
IPL 201
Booting default (grub2)
dasd-eckd 42a207: 0.0.0200: The specified record was not found.
1. What's the most likely cause for this error?
2. What script/files do we need to tweak to fix it ?
Note: On the golden copy, 200 is the root, 201 is a swap file.
Thanks,
Dave
