VM HA When LUNs on Half of Cluster Nodes Disappear

[jonh3000]

If the storage LUNs on half of the nodes in our cluster disappear will the VMs on those nodes automatically move over the nodes which the LUNs are still present?

We have two blade centers each with a dozen VM hosts (ESXi 5.5U2) all are in the same enterprise cluster.  In the event that we lose fiber LUN connectivity to one blade center what happens to the VMs on the VM hosts in that blade center?  Do they magically vMotion to the VM hosts in the other blade center?

Basically we're trying to create as highly available a cluster as possible utilizing share storage between two blade centers.

Hi,

Yes, VM will automatically move on the ESXi on which storage LUNs are available.

Means only vMotion will happen but Storage vMotion will not happen because you have not configured storage cluster and Storage DRS.

Hi,

HA will restart the VM to other cluster node.

Thanks
