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, right-click and select Edit Settings.
- Click the New device drop-down menu, select SCSI Controller.
- In new SCSI Controller, select VMware Paravirtual and set SCSI Bus Sharing to Physical. Click OK.
You must select same SCSI controller type, for example VMware Paravirtual, that you selected for the first virtual machine’s shared storage disks.Note: LSI SAS is supported, but VMware Paravirtual is recommended.
- Select the newly created virtual machine in step 1, right-click and select Edit Settings
- Click the New device drop-down menu, select Existing Hard Disk.
- In Disk File Path, browse to the location of the disk to be shared specified for the first node.
- Expand New Hard disk.
- Select the same SCSI ID you chose for the first virtual machine’s shared storage disks, (for example, select SCSI (1:0)).
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.
