Add cluster disk recourse to existing server 2008R2 multi site cluster with HP EVA CLX

[Lakshantha]

Hi.

I need to add a disk resource to an existing multi site cluster.

We have 2 sites and the cluster has 4 nodes, two nodes in each site.

HP EVA CLX is used and the LUN is visible in all 4 nodes and i can bring it online on each node and even create a volume etc.

But when i try to add the disk to the storage section of the cluster it won't come online.

When i check the event log i can see source: Microsoft-windows-filoverclustering, even id :1069 & 1034

am I missing something here or is there a special way to add disk resource to this type of clusters?

Pls help.

Tks.
