Microsoft Cluster and RDM

[voitsykh]

There are two hosts Dell R530 esxi 6.0 and a common SAS datastore Dell Md3200

The task is to create an MSCM cluster on two virtual machines with the operating system windows 2012R2

I see the solution through RDM. After a heap of read information, I created RDM and tied up virtual machines. As a result, there is a common disk under Windows, but when creating the cluster, Microsoft writes that SCSI 3 backup does not work. What can this be and how to deal with it? ...

Fibre Channel: Configurations using shared storage for Quorum and/or Data can be on Fibre Channel (FC) based RDMs (physical mode for cluster across boxesCAB, virtual mode for cluster in a boxCIB). Quorum or data can also be on both iSCSI or FCoE as well.

does not mention that it can be SAS. only quorum can be FC,iSCSI,FCoE

It is work.

I made mscs cluster and installed SQL cluster.

All test with storage - OK.
