<pre>Apologies for the delay in updates on this bug. The customer tested the PTF in
late April and had a similar issue where the host was unable to see attached
storage (multipath devices) after upgrade.
Our suspicion is that this behavior could be related to a lack of multipath
kernel support (dm-multipath.ko), due to the dracut "--no-kernel" param (which
results in an initrd built without kernel modules).
If this hypothesis seems reasonable, we'd like to request a new
SLES15-Migration PTF with the suse_migration_services scripts amended to remove
this flag ("--no-kernel"). From what I can tell, this param is set in
suse_migration_services/units/regenerate_initrd.py in the run_dracut function.</pre>
