Windows Server Failover Cluster Disk Witness Setup

I have a Windows 2012 R2 failover cluster running a MSSQL 2014 cluster resource. It's a 2-node cluster with a disk [Q:] witness presented to the cluster from our SAN over fibre-channel. One thing I notice though is that this disk witness Q: is also a storage resource under the MSSQL cluster resource. Surely that's an incorrect configuration? My understanding is the disk witness should only be part of the core cluster resource and not assigned as storage to any sub resource?

    Hi,

    Yes, the disk witness should only be the cluster core resource, shouldn't assign to other groups.

    Thanks for your time!
    Best Regards,
