You can set the SCSI controller type and the type of SCSI bus sharing for a virtual machine. SCSI bus sharing can set to none, virtual, or physical sharing types.

You can change the SCSI controller configuration for a virtual machine on an ESX/ESXi host only.

Caution

Changing the SCSI controller type might result in a virtual machine boot failure.

You can also specify whether the SCSI bus is shared. Depending on the type of sharing, virtual machines can access the same virtual disk simultaneously on the same server or any server.
