What to do next
You can add a hard disk or other SCSI device to the virtual machine and assign it to the new SCSI controller.
Change the SCSI Bus Sharing Configuration in the vSphere Web Client
You can set the type of SCSI bus sharing for a virtual machine and indicate whether the SCSI bus is shared.
Depending on the type of sharing, virtual machines can access the same virtual disk simultaneously if the
virtual machines reside on the same ESXi host or on a different host.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, expand SCSI controller, and select the type of sharing in the SCSI Bus
Sharing drop-down menu.
Option Description
None
Virtual disks cannot be shared by other virtual machines.
Virtual
Virtual disks can be shared by virtual machines on the same ESXi host.
Physical
Virtual disks can be shared by virtual machines on any ESXi host.
For virtual or physical bus sharing, select Thick provision eager zeroed when you create the disk.
3 Click OK.
Change the SCSI Controller Type in the vSphere Web Client
You configure virtual SCSI controllers on your virtual machines to attach virtual disks and RDMs to.
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.
CAUTION Changing the SCSI controller type might result in a virtual machine boot failure.
Prerequisites
n
Verify that you are familiar with the limitations and conditions for configuring SCSI controllers. See
“SCSI and SATA Storage Controller Conditions, Limitations, and Compatibility,” on page 125.
n
Verify that you have the Virtual machine.Configuration.Modify device settings privilege on the
virtual machine.
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, expand SCSI controller, and select a SCSI controller type from the
Change Type drop-down menu.
The vSphere Web Client displays information about what will happen if you change the controller type.
If you have selected a controller type that is not recommended for the virtual machine's guest operating
system, a warning is displayed.
3 Select whether to change the controller type.
n
Click Change Type to change the controller type.
n
Click Don't change to cancel the change and keep the original controller type.
Do not select a BusLogic Parallel controller for virtual machines with disks larger than 2TB. This
controller does not support large capacity hard disks.
