F. Load Segment: Only use this variable if you are using Load Segments to preferentially
control hardware startup/shutdown behaviour (e.g. servers and storage on separate
profiles).
G. Master - Shutdown Duration: The time (in seconds) it takes for the host to shut
down (including any vMotion activities). Make sure that the time between
“
Maintenance Timer ” and “ Master - Shutdown After ” gives enough time for any
VM migrations to occur. Otherwise the migrations will fail and the VM will shut down on
the original host location.
H. Master - Shutdown After: The time (seconds) following a power failure that the
shutdown command should be sent to the host.
