Hello,
We have a 3 nodes Hyper-v Cluster running Windows Server 2012. Recently we start having error below intermittently on a node, and the VMs running on this host and LUN will power off.
Alert: Cluster Shared Volume is no longer accessible from cluster node
Source: Cluster Service
Path: HV01.itl.local

Alert description: Cluster Shared Volume 'Volume1' ('Cluster_Vol1_R6') is no longer accessible from this cluster node because of error 'ERROR_TIMEOUT(1460)'. Please troubleshoot this node's connectivity to the storage device and network connectivity.
The only changes made recently is we installed VEEAM on test basis for DR replication. We switched off the Veeam server and stop the Veeam Services on the Hyper-V Hosts but we are still having same issue.
We are using an EMC SAN connected via FC as Shared storage and Powerpath as Multi-Pathing. No errors were found on the SAN.
I don't think the issue is related to the number of IO as we also experienced the issue at midnight during the week-end where no one was working.
Any help would be very much appreciated.
Thanks.
