To allow shared access to disk resources, point to existing disks on the VM, the first node of a WSFC cluster. Use the same SCSI IDs while assigning disks to all additional nodes.
Before you begin, obtain the following information:
- Obtain SCSI IDs for all virtual disks to be shared.
- Obtain disk file path on datastore for all shared disks.
Note: The procedure for clustered VMDK, pRDMs and vVol is the same.
- In the vSphere Client, select the newly created virtual machine, a second node of the WSFC, right-click and select Edit Settings.
- Click the New device drop-down menu, to add a storage controller select VMware Paravirtual, and click Add.
Note: LSI SAS is supported, but VMware Paravirtual is recommended.
- Click the New device drop-down menu, select Existing Hard Disk, and click Add.
- In Disk File Path, browse to the location of the disk to be shared specified for the first node.
- Select Physical as the compatibility mode and click Next.
- Select the same SCSI ID you chose for the first virtual machine’s shared storage disks (for example, SCSI (1:0)), and click OK.
Note: The disk SCSI ID for this virtual machine’s shared storage must match the corresponding SCSI ID for the first virtual machine.
- Click OK.
The wizard creates a new hard disk.
- In the New Virtual Machine - Edit Settings dialog box, expand SCSI controller and select the Change Type drop-down menu.
- Select the appropriate type of controller, depending on your operating system.

- Click OK.
- Set SCSI Bus Sharing to Physical and click OK.
