Add Hard Disks to Additional Nodes for Clusters Across Physical Hosts

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.

Prerequisites

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.

Procedure

1. In the vSphere Client, select the newly created virtual machine, right-click and select Edit Settings.
2. Click the New device drop-down menu, select SCSI Controller or NVMe Controller.
   • If a new SCSI Controller is created, select VMware Paravirtual and set SCSI Bus Sharing to Physical. Click OK.
   • If a new NVMe Controller is created, set NVMe Bus Sharing to Physical. Click OK.

   You must select same SCSI controller or NVMe controller type.
3. Select the newly created virtual machine in step 1, right-click and select Edit Settings
4. Click the New device drop-down menu, select Existing Hard Disk.
5. In Disk File Path, browse to the location of the disk to be shared specified for the first node.
6. Expand New Hard disk.
7. Select the same SCSI or NVMe ID you chose for the first virtual machine’s shared storage disks, (for example, select SCSI (1:0) or NVMe (1:0)).
   Note: The disk SCSI or NVMe ID for this virtual machine’s shared storage must match the corresponding SCSI or NVMe ID for the first virtual machine.
8. Click OK.
