C H A P T E R 1 0 Configuration for Clustering
335
• One or more virtual disks that will be shared attached to the secondary SCSI host
adapter
Important Notes
• Each virtual machine by default has five PCI slots available. In this configuration
(two network adapters and two SCSI host bus adapters), four of these slots are
used. This leaves one more PCI slot for a third network adapter if needed.
• VMware virtual machines currently emulate only the SCSI-2 disk reservation
protocol and do not support applications using SCSI-3 disk reservations.
However, all popular clustering software (including MSCS and VCS) currently
uses SCSI-2 reservations.
Two Node Cluster with Microsoft Cluster Service on a Single
ESX Server Machine
This procedure creates a two-node cluster using Microsoft Cluster Service on a single
ESX Server machine and uses the following:
• Portsaid = host name of node 1 of the cluster
• Kena = host name of node 2 of the cluster
• Arish = public host name of the cluster
• sharedfs = VMFS volume label of the shared storage
• vms = VMFS volume label of the local storage
Note: Virtual disks stored on vms and sharedfs can also be stored on the same
partition. In this case, use the partition label on which these virtual disks reside.
Creating the First Node’s Base Virtual Machine
1. Access the VMware Management Interface at
https://<hostname>/ and log on as the user who will own the virtual
machine.
2. Click Add Virtual Machine.
3. Keep the default Guest Operating System selection of Microsoft Windows
2000 Server.
Note: This example uses Microsoft Windows 2000 Server as the guest operating
system. You may substitute another Windows operating system that supports
Microsoft Cluster Service.
4. Change the Display Name field to describe the virtual machine — for example,
MSCS Node 1 (Portsaid).
