We’ve finally completed this migration. I’m not exactly sure, but I believe the missing
step was to manually run "rescan-scsi-bus.sh —forcerescan” on each ovirt server to
make sure they all saw the new LUN. This allowed the new hosted_engine storage domain to
activate and the setup to complete?
Thanks,
Devin

Hello,
We are attempting to move a hosted engine from an NFS to an iSCSI storage domain,
following the normal backup / restore procedure.
With a little intervention in the new hosted engine VM, everything seems to be working
with the new engine and the process gets to the point of trying to create the new iSCSI
hosted_storage domain. At this point, it fails with "Storage domain cannot be
reached. Please ensure it is accessible from the host(s).”
The host itself does see the storage, and everything looks fine using iscsiadm and
multipath commands. However, if I look at the new hosted_storage domain in the new
engine, it’s stuck “unattached” and the “hosted-engine --deploy --restore-from-file …”
command loops at the "Please specify the storage you would like to use” step.
Please see below for an excerpt of the output and logs, and let me know what additional
information I can provide.
Many thanks,
Devin
Here’s the output from the “hosted-engine --deploy --restore-from-file …” command.
