I am trying to create a cluster that consists of two dell Windows 2012 boxes and Drobo 1200 acting as SAN. When I ran cluster verification utility I received an error:
“Failed while verifying removal of any Persistent Reservation on physical disk”
I created cluster anyway and when I tried to add storage I got:
“0x45d' ('The request could not be performed because of an I/O device error.').
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster
Manager or the Get-ClusterResource Windows PowerShell cmdlet.”
Any suggestions ?
