Hi all,
Just trying to implement a UPS solution here and am getting a bit stuck.
Client has the following:
2x HP R/T3000 UPS with network cards. Both UPS attached to VCentre via USB also.
1x HP DL380 G7 (VCentre server, win 2008)
2x HP DL380 G7 (VSphere1 and VSphere2) - esxi version 4.1
HP P2000 array
Just wondering if there is a simple way to get the VMs to suspend in the event of an extended power failure, then have the hosts shut down?
When power returns, is it possible to have the hosts power back on, and the VMs then resume from suspended state?
I've installed VMA 4.1 but haven't gotten to the APCUPSD step, as it is not an APC ups. Also seems like a VERY convoluted process for what should be a simple task.
Can something like this be configured through HP SIM, or another tool?
Any help greatly appreciated 
Welcome to the Forums
On each Hosts Configuration tab under "Edit Virtual Machine Startup/Shut Down Settings" You can control the VMs in behavior case of host shutdown or startup. In a cluster these settings will follow the VM.
However, if HA is enabled in this cluster, these settings are silently disabled. (Can configure but will be ignored)
So with a HA cluster you will need to write scripts to shutdown/suspend VMs before Host shutdown and also Startup/Resume VMs after host is back up.
HA will not startup/resume a VM that has been gracefully shut down or suspended
Please award points if you find this helpful/correct
Thanks for the reply
Is there a repository of scripts around here at all for doing this? Would this need to be done via vMA, or is there an easier way? Maybe via vSphere CLI client?
The way I have investigated so far is via apcupsd on vMA (using the great ghettoups script), but I doubt this solution would work for a HP UPS.
I just need some software that will receive an SNMP trap for low battery, and begin the shutdown/suspend process.
Currently I have Vcentre shutting down safely when the power goes out (via USB monitoring), but it doesn't know that it needs to power the hosts down as well.
That is good info regarding HA, would have tripped me up!
Cheers
OK to help the other n00bs out there like me
Good article:

So steps are:
Launch PowerShell as an admin
Type in: Set-ExecutionPolicy RemoteSigned
Type Y (for yes) when prompted.
I then created 2 files using Notepad:
First file, saved to C:/scripts/powerdown.vbs and its contents, this will basically run the second script:
Set objShell = CreateObject("Wscript.Shell")
objShell.Run("powershell.exe -noexit c:\scripts\powerdown.ps1")
Second file, saved to C:\scripts\powerdown.ps1 and its contents:
echo "hello world"
I then pointed HP Power Protector at C:/scripts/powerdown.vbs
Once I get the PS1 script right I'll paste it into powerdown.ps1
Discovered you need to have this first line added before PowerShell will know WTF you are doing
