Windows 2008 SQL Cluster LUNs was virtualized from Axiom Pillar 600 Storage to HDS VSP G800 Storage. After mapping the external Ldev and trying to start the SQL cluster , all databases were inaccessible, although we could access the data and we could read/write to the volume after virtualization.
We revert the Cluster volumes to the old storage (remove virtualization for the LUNs)and it works fine. I have found that the Windows cluster reserved the old unique id for the LUN containing the databases (using diskpart utility). Is there a work around for this
Kindly note that I have done the same procedure to another SQL cluster and it worked fine, the LUN is not reserved or locked on HDS box!!
