Hi Mark,
Yes, we did go thru what we believe is the correct modules for FCP support
in the initrd. We ran the mkinitrd after chroot to the new
SCSI/LVM/Multipath-tools
design. We had changes in lvm.conf, created multipath.conf, changes to
udev.rules.
mkinitrd and zipl output:

Mark replied:
Sounds like you did not rebuild your initrd with the FCP driver and
parms needed to find the storage and re-run zipl.
