Useful settings for VMware

This section describes useful advice about using Vmware.

Using parameters to stop the system at

hardware failure

At hardware failure, an interrupt called NMI (*1) is issued to the OS to stop the

system during the hardware recovery process. If Vmware ESX/Vmware ESXi (*2) is

used, however, the default settings do not stop a system when NMI is issued. As a

result, unexpected behavior may occur because the system keeps running at

hardware failure.

NMI (Non-Maskable Interrupt): hardware interruption that cannot be masked by

VMware version is displayed such as VMware ESX, VMware ESX Server, and VMware

ESX Server 3i.

Vmware ESX 4.0/Vmware ESXi 4.0 or later versions are provided with parameters to

stop the system when NMI is issued. Enable the setting by following the procedure

below. This can prevent unexpected behavior at hardware failure. It is highly

recommended that you should set these parameters.

Vmware ESX Server 3.5 is also provided with parameters. Enable the setting by

following the procedure below. If the enabled parameter does not work, it is

recommended that you should upgrade ESX 3.5 to ESX 4.0.

VMware ESX Server 3.5 Update 4

VMware ESX Server 4.0 (including Update 1)

VMware ESXi Server 4.0 (including Update 1)

 Setting procedure

Procedures are different depending on a VMware version. Thus, configure the

setting for your environment.
