Hi,
I have two ESXi 5.0 plugged into a Smart UPS 3000. Servers are in a cluster and HA has been configured
vCenter is installed on its own hardware and connected to the same Smart UPS 3000 with a USB cable..
What is the best way to properly shutdown all my guests and host when my UPS battery is low ?
Thank you !
Hi, try to avoid using PCNS to shutdown ESX hosts as it is isuing command to shutdown HOST, which in case of a cluster mean powering off (non-graceful shutdown) guests, because you cannot configure host autostart/autoshutdown parameters in a cluster. I am using a powershell script initiated by UPS shutdown script residing on a vCenter server to shutdown whole virtual infrastructure.
Something like this will do http://www.sheenaustin.com/2011/02/20/vmware-ups-shutdown-script/
You may want to edit the script to suit your environment.
Should work fine even with USB connected UPS. Remeber that after power returns you have to manually start each guest (HA wont start them automatically). This may be a problem if outage happens during night and guests wont be up in the morning. In this case aditional powershell scripting should be made to start the guests.
