I already predicted that this was bound to happen sooner or later. It only took William Lam, aka lamw, a couple of days to enhance the work that Joseph Holland did. Joseph wrote a procedure that let’s APC’s software initiate a shutdown of the VM’s and ESXi host when a power failure occurs. Joseph’s solution included a modification of ESXi which means no VMware support.
I hinted William via twitter and he came up with a perl script that uses the API to initiate the shutdown of the VM’s and the ESXi host. This script will be run on the VIMA VM. There’s no need to change the ESXi host anymore!
ghettoShutdown.pl – This script initiates the shutdown of all VM(s) within an ESX/ESXi host excluding the virtual machine that’s monitoring the UPS device and then shutdowns the host. It accepts two commandline parameters: –sleep the duration in seconds to wait after a VM has initiated the shutdown before moving onto the next VM (shutdownVM() is non-blocking function) and –ups_vm the name of the displayName of your VM that is monotiring the UPS device [more details to come later].
upsVIShutdown.pl – This script is a wrapper which will hold the configurations of the order of hosts to shutdown. It may be used inconjunction with other UPS monitoring utility, though with our example, it’ll be placed in the apccontrol script to execute upon a power interuption.
Now head over to the VMware Communities, download the script and testdrive it! Awesome work William!
As it seems Tripwire is preparing a new toolkit.
