Have a 2008 R2 SP1 Cluster with three nodes. Try to add a forth node. Have installed Hotfix 2531907 on all four nodes.
When running cluster validation, I'm getting the error "Failed to get SCSI page 83h VPD descriptors for cluster disk.." on node one. But node one is productive with a lot of running VM's and has no visible problem. There aren't any errors in the failover cluster manager.
Does anyone have an advice how to further troubleshoot this problem? Would prefer to add the forth node without selecting the option "will never need Microsoft support for this cluster..."
Thank you all in advance for any advice
Franz
