HP UPS Management Module Installation and Configuration Guidelines for VMware ESX

SDScript file modification example

If the virtual machines do not shut down before the VMware server shuts down, you might receive the

following warning:

Stopping VMware ESX Server services:

mkload_mod PANIC: vmfs3: Device or resource busy

To ensure that the virtual machines are properly shut down, you can modify the SDScript. For

example, to shut down a VMware ESX 3.0.1 server with one Microsoft® Windows® 2003 virtual

machine and one Red Hat Enterprise Linux 4.0 virtual machine, enter the following:

echo "Shutdown script has been executed." | wall

echo "PLEASE WAIT WHILE THE VIRTUAL MACHINES ARE BEING SHUT DOWN" | wall

/usr/bin/vmware-cmd /vmfs/volumes/47c2ce23-bad20214-7e49-

0016353ce250/Win\2K3\R2\SP2/Win\2K3\R2\SP2.vmx stop

/usr/bin/vmware-cmd /vmfs/volumes/47c2ce23-bad20214-7e49-

0016353ce250/RHEL4\U5/RHEL4\U5.vmx stop
