In an MSCS cluster, storage disks are shared between nodes. You set up a quorum disk and an optional shared storage disk with VVol Storage.

Prerequisites

Before you add hard disks to the first node, complete the following tasks:

  • For each virtual machine, configure the guest operating system’s private and public IP addresses.
  • Ask your SAN administrator for the location of unformatted SAN LUNs. The hard disks you create in this task must point to SAN LUNs.

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 New Hard Disk, and click Add.
  3. Select the disk size.
  4. Under Disk Provisioning, select either Thick or Thin Provision.
  5. Expand the New Hard Disk.
  6. From the Virtual Device Node drop-down menu, select a new SCSI controller (for example, select SCSI (1:0)).
    Note: You must select a new virtual device node. You cannot use SCSI 0.
  7. Click OK.
    The wizard creates a new hard disk and a new SCSI controller.
  8. In the New Virtual Machine - Edit Settings dialog box, expand SCSI controller and select the Change Type drop-down menu.
  9. Select the appropriate type of controller, depending on your operating system.
    Operating System Type of Controller
    Windows Server 2003 SP1 and SP2 LSI Logic Parallel
    Windows Server 2008 SP2 and above LSI Logic SAS and VMware Paravirtual
    For supported guest operating systems see Table 4.
  10. Click OK.
  11. In the New Virtual Machine - Edit Settings dialog box, expand SCSI controller and select the SCSI Bus Sharing drop-down menu. Set SCSI Bus Sharing to Physical and click OK.

Results

The virtual machine is connected to a public network and a private network with two virtual switches, and is connected to the quorum disk on FC SAN and the virtual machine virtual disk on local or remote storage.
