Change the SCSI Controller Type in the VMware Host Client

You can attach virtual disks and RDMs to virtual machines by configuring virtual SCSI controller on the virtual machines.

The choice of SCSI controller does not affect whether your virtual disk is an IDE or SCSI disk. The IDE adapter is always ATAPI. The default for your guest operating system is already selected. Older guest operating systems have BusLogic adapter as their default controller.

If you create an LSI Logic virtual machine and add a virtual disk that uses BusLogic adapters, the virtual machine boots from the BusLogic adapters disk. LSI Logic SAS is available only for virtual machines with hardware version 7 or later. Disks with snapshots might not experience performance gains when used on LSI Logic SAS, VMware Paravirtual, and LSI Logic Parallel adapters.

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

Prerequisites

Power off the virtual machine.
