Device ‘SCSI Controller 1’ is a  SCSI controller engaged in bus-sharing

I was just adding RDM shared disks to configure a Microsoft Failover Clustering in one of my working projects, and it was failing with an error message. This was a quick fix but I thought to publish as an article to make your life more easier, if you have a similar situation.

I wanted to add a new SCSI Controller and wanted to make it as “Physical” and type as “VMware Paravirtual ” which is a primary configuration requirement for this clustering configuration.

It was failing with the below error message and I was not able to save the configuration after changing the controller type. There was no any configuration errors with the Virtual Machines and it was configured with the same standard as other working cluster Virtual Machines.

After checking sometime with the Virtual Machines I realized that it failed due to the previous snapshot taken to some changes in the Virtual Machines. After deleting the snapshot, the required configuration was successful.

I hope this will help someone to overcome with a similar situation.
