PowerCLI: Enable / Disable Alarm Actions on Hosts / Clusters

Hello All,

I have done some serious googling, and am about to accept that it is not possible through PowerCLI.

But I wanted to make a last effort by asking you guys.

For ESXi host maintenance, I want to use a PowerCLI script which does this:

1. - disable alarm actions on Cluster
2. - disable alarm actions on Hosts
   
   
3. - perform maintenance (can be anything, but will include host reboots)
   
   
4. - enable alarm actions on Hosts
5. - enable alarm actions on Cluster

Because we have 300+ ESXi hosst, you can imagine I want to do this scripted.

Is there any way to disable/enable alarm actions through PowerCLI ?

Thanks and kind regards,

Harold
