I suppose we'll disconnect manually, if we=20 decide to use direct LUNs instead of Storage domain volumes (some=20 issues with SD volumes, as explained in another mail thread of mine).

Hi Boyan,
Generally we don't disconnecting external Lun disks when we remove them=
from the oVirt management. You can disconnect them manually from the host, or use restart.
IIRC one reason for that, is because we might have Storage Domains whic= h use the same target. another reason is that we keep those sessions, so it will be easier to establish connection when reusing the target.

Hello,
I have ovirt 3.3.2 running with FC19 nodes. I have several virtual machines that use directly attached iSCSI LUNs. Discovering, attaching=
and using new LUNs works without issues (vdsm needed some patching to work with Dell Equallogic, as described here https://sites.google.com/a/keele.ac.uk/partlycloudy/ovirt, but that's = a separate issue). Also live migration works well between hosts and the LUNs get properly attached to the migration target host.
However, I don't see any way to disconnect/remove LUNs that are no longer needed (e.g. VM is removed). What is the recommended way to remove old LUNs, so that the underlying iSCSI sessions are disconnecte= d? Especially if a VM has been migrated between hosts, it leaves the LUNs=
connected on multiple nodes.
Thank you in advance!
