C H A P T E R 1 0 Configuration for Clustering

For this exercise the VMFS partition for the internal storage on each ESX Server
computer is labeled vms. The VMFS partition for the shared storage is labeled
sharedfs.
• The VMFS partition for the internal storage on each ESX Server machine is
labeled vms.
• The VMFS partition for the shared storage is labeled sharedfs.
Each ESX Server machine must have an additional physical network adapter assigned
to the virtual machines to use for the private network that monitors the heartbeat.
The procedure assumes this network adapter uses the device named vmnic1. You
should connect the private network adapter to a separate network from that used by
the public network adapter.
Creating the First Node’s Base Virtual Machine
Follow the procedure in Creating the First Node’s Base Virtual Machine on page 335,
with the following changes:
• In the Virtual Disk Configuration section, in step 10 click Edit next to SCSI
Controller 1 to change the bus sharing from none to physical instead of virtual.
From the Bus Sharing drop-down list select physical, then click OK.
• In the Network Device Configuration section, in step 3 use vmnic1 instead of
vmnet_0 as the device used by Ethernet Adapter 1.
• Access the virtual machine menu by clicking the arrow to the right of the virtual
machine icon. Choose Configure Options. Under Verbose Options, click the
click here link.
Change the specifications of scsi1:1.name and scsi1:2.name to use the
strict vmhba name (for example, vmhba0:1:0:1:shared1.dsk) for the
VMFS partition, rather than the VMFS name (for example,
sharedfs:shared1.dsk). The reason for this change is that if one ESX
Server machine reboots while a virtual machine on the other physical machine is
reserving the shared SCSI disk, ESX Server cannot read the VMFS name on the
shared disk when it is loaded and initialized. If the shared virtual disk is not
specified using the full vmhba name, ESX Server cannot determine the disk
specified by the VMFS name and gives an error when restarting the virtual
machine.
When you have made these changes, click OK.
In addition to these minor changes, you need to change the access rights of the VMFS
partition where you store the shared virtual disks. By default VMFS partitions are
