Hyper V CSV Issue

Hi All

Hope someone can help or point in the right direction.

We are having an issue with Cluster shared volume. We have setup 2 physical hosts which boot from iSCSI OS hosted on a SAN. These boot without any issue and work fine. I have installed Hyper V and Failover Cluster and configured a cluster. i created a 750GB volume on the san and presented it to the hosts and then added in as a cluster shared volume, we could live migrate between the hosts with no problems. We simulated a power failure of one of the hosts which the cluster correctly migrated the VM machine across to the other node, when the node was brought back online it is recognised within the cluster but it doesn't read the disks that have been allocated as CSV.

When the node comes back online it renames the cluster folder in the c: to ClusterStorage.000

Is this something that wont work correctly because of the iSCSI boot of the OS

Any help is appreciated.

It sounds like you have a problem with MPIO. I have seen it with hosts that don't boot to SAN.

Make sure that the MPIO software is properly loaded on both hosts and that it has ownership of all connections to the SAN.
