Hi
I have a PV MD3420 connected to one PE R720 via SAS, I have created a Server 2012R2 Failover Cluster for my storage. I want to now add the second node to the cluster but have made an administrative error when configuring the MD3420.
I created a Host Group for my Failover Cluster nodes and have added Server 1 to this Host Group. I then configured Server 1 to have access to the LUNs I created rather than the Host Group.
Now I want Server 2 to be able to see the storage, I have added Server 2 to my Host Group but since I configured Server 1 to have access to my storage LUNs rather than the Host Group I cannot get Server 2 to have permission to access the storage (since the LUNs can be assigned to one entity at a time)
If I change the LUN access to the Host Group rather than Server 1, will Server 1 have continuous access to the storage or will it go offline and need reconfiguring in Windows? I have a live environment running on top of the storage and don't want to play around with it.
Many thanks
