Add Hard Disks to the First Node for Clusters Across
Physical Hosts
In an MSCS cluster, storage disks are shared between nodes. You set up a quorum disk and an optional
shared storage disk.
Prerequisites
Before you add hard disks to the first node, complete the following tasks:
n
For each virtual machine, configure the guest operating system’s private and public IP addresses.
n
Ask your SAN administrator for the location of unformatted SAN LUNs. The hard disks you create in
this task must point to SAN LUNs.
n
If you are using VVol storage for shared disk, please see Add Hard Disks to the First Node for
Clusters Across Physical Hosts with VVol.
Note Use RDMs in physical compatibility mode.
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 RDM Disk, and click Add.
3 Select an unformatted LUN.
4 Select a datastore.
This datastore must be on a SAN because you need a single shared RDM file for each shared LUN
on the SAN.
5 Select Physical as the compatibility mode.
6 Select a new virtual device node (for example, select SCSI (1:0)), and click Next.
Note This must be a new SCSI controller. You cannot use SCSI 0.
7 Click OK to complete creating the disk.
The wizard creates a new hard disk.
8 In the New Virtual Machine - Edit Settings dialog box, expand SCSI controller and select the
Change Type drop-down menu.
