[ovirt-users] Hosted Engine down and not visible on any host

Hi, We have a 4 node ovirt cluster running at 4.4.1.5. We are running it on iSCSI shared Storage. The hosted engine is running on its separate iSCSI shared storage. Hosted Engine went down all of a sudden and no where to be found on any of the nodes when I do virsh list --all All other VM's are showed in the list but cannot see the hosted engine? when we try to bring hosted engine up using "hosted-engine --vm-start" it errors out with message "vm does not exist". The shared iscsi storage ip on which the HE vm was running is pingable, but when we perform "hosted-engine --connect-storage" we are getting request timeouts after 60 seconds. Any ideas to restore back the hosted engine and the cluster highly appreciated.
