[Users] Host offline due to storage error

[Ian Mordey]

Hi there
I've got a 3 node oVirt 3.3.1 setup connecting to an Equallogic iSCSI SAN
array. My nodes keep going offline with these errors:
Host reports about one of the Active Storage Domains as Problematic.
Host cannot access one of the Storage Domains attached to the Data Center
<DC> Setting Host state to Non-Operational

The host is then fenced, reboots and comes back up normally.

I see some of these errors prior to the event:
2013-12-10 13:36:49,442 ERROR
[org.ovirt.engine.core.vdsbroker.vdsbroker.ListVDSCommand]
(DefaultQuartzScheduler_Worker-14) Command ListVDS execution failed.

continuing.

(DefaultQuartzScheduler_Worker-59) Command GetCapabilitiesVDS execution
failed. Exception: VDSNetworkException: java.net.ConnectException:

Any ideas where to look? I can't see any errors on the switches or SAN..

Thanks
Ian
