Adding a SAN disk to a pre-existing active windows cluster

[Adam Garsha]

Do these steps appear correct?
1. present the LUN (using lun masking) to one member of the cluster
2. Initialize and format
3. Use cluster to GUI to add it as a resource
4. adjust lun mask so that both nodes can see the disk
5. test failover

Our problem lies at step 3. The disk doesn't show up in the list of disks that we can clusterize.

Anyone run into this before? (It is not the SAN zoning nor presentation--unless you are supposed to present to all nodes from the get-go).

Thanks,

The procedure seems to be good. Ensure that the disk is "BASIC" before trying to add it as a cluster resource.

Adam,

I found this procedure from google...

1) Create Volumes

2) Present LUNs to Node1

3) On Node1:

- Rescan for hardware changes

- Write the disk signature

- Set disk to basic

- Create Partition

- Assign Drive Letter

- Create the cluster disk resources...add this resource to a new group. If

there are no disks listed in the "Parameters" field when creating the disk,

see http://support.microsoft.com/kb/555312

4) Present LUNs to Node2

5) Failover the disk resource to Node2

6) Move disk resource to your SQL group and adjust accordingly

7) Test
