Public bug reported:

Reddit thread:
https://www.reddit.com/r/linuxadmin/comments/1g04j16/multipath_on_ubuntu/

Upstream bug: https://github.com/opensvc/multipath-tools/issues/56
Upstream commit: 
https://github.com/opensvc/multipath-tools/commit/88d46ea62c6633ac01897c96a5c8fb429f0971ac

Testing PPA: https://launchpad.net/~mitchdz/+archive/ubuntu/mpath-jammy-
sas-drive-not-found

[ Impact ]

Some SAS devices (e.g. Seagate factory recertified 'white label' drives)
may come with the Vendor field blank. This causes Multipath to fail to
complete the discovery of those devices.

This is a bug that all releases are exposed to, and relatively silently
fails which can make it difficult for the user to pinpoint the issue
(see reddit thread). The fix is relatively small which makes it a good
SRU candidate, but reproducing the bug without special hardware may be
challenging.
