This is the best resource I’ve ever seen outlining this process, thanks.

Quick question, I configured the heartbeat network as ‘Cluster only’ yet still got a message that it could not bring the cluster online because the heartbeat network was not configured to allow client access. Did I miss a step?

Thank you! I’m not sure to understand, by « on line » you talk at the windows level or at the cluster level? For AAG, disks should not be configured as Cluster resources. Each SQL node must have its own “local” disks. You can use virtual disk (VMDK) or RDM LUN but for Production it is not recommended to use virtual disks (VMDK) for database and transaction log files (it’s ok for a mock-up), so you need to present different RDM disks or to each node (not the same to multiple nodes). What is the error with VMDK ?

Nice article.

I am currently setting up a server Windows 2012r2 non-shared disk cluster to have a node at each data centre and use SQL AG’s to do the replication. I have VMware 5.1u1. I have an issue in presenting the disks to the guest os, they will not come on line unless I make them RDM’s, if I use datastore disks it just gives errors.

Is there a secret to using non-shared disk from VMware that I am missing?
