1. Please upgrade to the latest release first.
2. Please ensure that on the host everything is properly connected, zoned,
etc. That it can access those LUNs.
3. Please ensure no one erased the domain LUNs - are the VMs using it as
well?
4.  Please provide the relevant VDSM log - when things started to go south
- as well as Engine log.

I don't think that's the right venue for urgent requests, btw.
