So if you’re like me, better safe than sorry… than you’ve probably set your ESX 3.5 U2 HA cluster to “shutdown VM” instead of “Power off VM” or “Leave VM powered on”. By now most of you probably already noticed that when an isolation occurs HA will allow the VM to shutdown clean within 5 minutes. When the 5 minutes are past HA will shutdown the VM’s no matter what.
But for some of you 5 minutes(300 seconds) might just not be long enough, or if you have an ultra fast environment 5 minutes might just be to damn long….
So what can you do to shorten or extent… It’s easy, open up you HA cluster settings and click on advanced options and add the following:
das.isolationShutdownTimeout – values in seconds, default is 300
I’ve also updated my HA advanced settings blog! If anyone has more advanced settings that aren’t on the list let me know!
