“das.maskCleanShutdownEnabled” :This is enabled by default from vsphere 5.0 , ie HA is going to assume a virtual machine needs to be restarted when it is powered and isn’t able to update the config files. (Config files contain the details about the shutdown state normally, was it an admin initiated shutdown?)
disk.terminateVMOnPDLDefault : This is not enabled by default . If this setting is not explicitly enabled then the virtual machine will not be killed and HA won’t be able to take action. In other words, if your storage admin changes the presentation of your LUNs and removes a host accidentally the virtual machine will just sit there without access to disk. The OS might fail at some point, your application will definitely not be happy, but this is it.

Wonderful Link for configuring the parameter via powercli.
