[Bug 1902855] Re: two identical disks are only offered as a multipath device

[Christian Ehrhardt ]

With multipath running in the install environment how does e.g. "sudo multipath -ll -v 3" look like?
You'd usually expect all multipath devices to be listed with path and ID e.g.:

mpatha (36005076306ffd6b6000000000000240a) dm-3 IBM,2107900
size=10G features='1 queue_if_no_path' hwhandler='1 alua' wp=rw
`-+- policy='service-time 0' prio=50 status=active
  |- 0:0:0:1074413604 sdc   8:32   active ready running
  |- 0:0:1:1074413604 sdh   8:112  active ready running

I wonder if we can derive anything from this in your case.

Bug description:
  two identical SSDs are only offered as a multipath device in the
  server installer, not as single devices. The install succeeds, however
  the following boot falls back to the initramfs because the volume
  group cannot be found. Same hardware configuration as in LP: #1902845.

  blacklisting the dm_multipath module on the installer boot,  shows the
  two disks, however the installer later fails because the multipath and
  multipathd commands fail.
