Hi,
I want to import a FC storage domain from an oVirt 4.3.10 setup to a fresh
installed oVirt 4.5.5.
I could move domain to maintenance, detach, remove from 4.3.10 and import with
activate option to 4.5.5 for one FC LUN fine.
When i tried for the second FC lun - during import,activate i get "Error while
executing action Attach Storage Domain: Internal Engine Error" and in
engine.log i get " Query 'GetUnregisteredDisksQuery' failed: null',
and on the standalone engine, i get :-
2024-06-26 07:15:07,277+05 ERROR

I have checked using "Scan Disk" on the FC lun before exporting from 4.3.10 and
there were no floating disks. I have checked if any of the VM's on the domain
have any of their disks on any other storage domain - there are none.
On the host used for importing the domain, i get :-

Any help will be useful, we are moving from 4.3.10 on IBM servers and storage
to 4.5.5 on DELL servers and storage
