This works after upgrading to 15.2.8 from 15.2.5.
I see an improvement that "orch host add" does some checking
and shows explicit messages if anything is missing.
But I am still not sure how 15.2.5 worked initially when building
the cluster. Anyways, I am good now.
Thanks!
Tony

Just a note: you don't need to install any additional package to run
ceph-volume:
host1:~ # cephadm ceph-volume lvm list
Did you resolve the missing OSDs since you posted a follow-up question?
If not did you check all the logs on the OSD host, e.g.
'journalctl -f' or ceph-volume.log in /var/log/ceph/<UUID>/? I would
expect to find clues what's going on.

Hi Eugen,
I installed ceph-osd on the osd-host to run ceph-volume, which then
lists all devices. But "ceph orch device ls" on the controller (mon
and mgr) still doesn't show those devices.
This worked when I initially built the cluster. Not sure what is
missing here. Trying to find out how to trace it. Any idea?
Thanks!
Tony
