Drives on RAID controller for S2D

Chris Leit 0 Reputation points

Dear community,

following this article I tried to enable Cluster S2D for my RAID drives with this registry key. After that Get-PhysicalDisk Shows that the drives are "CanPool" = "True"

When I try to Enable-ClusterStorageSpacesDirect I always get an error that my bustype is not supported. Thanks for your support.

    It is not possible to use drives with "RAID" bus type to create S2D. You will need to use HBA, which allow Windows to connect to drives directly. Check for more information:

    In case you don't have an option to replace RAID controller with HBA, you can use StarWind VSAN. It can be used to create replicated storage pool for Failover Cluster.
