Doc Text:	When power management start or restart action is executed, we switch host to REBOOT state and wait for number of seconds which are defined in 'ServerRebootTimeout' engine-config property. After that timeout we switch host to NON_RESPONSIVE state, so the host monitoring can handle the host.	Story Points:	---

Description Petr Matyáš 2017-02-17 14:15:06 UTC

Description of problem:
Now it's about 2 minutes before fencing mechanism tries to fence the host again, but my host takes about 3-4 minutes to boot, this results in fencing the host again and again.

Version-Release number of selected component (if applicable):
4.1.1-1

How reproducible:
always

Steps to Reproduce:
1. have a host that takes more than 2 minutes to boot
2. fence the host
3.

Actual results:
repeated fencing

Expected results:
one successful fence

It make sense to wait a bit after successful power management start operation in fencing flow before we allow host monitoring to try to contact the host. We are using ServerRebootTimeout (by default 5 minutes) during install host flow when restart of the host is required.

So I'd use the same config value ServerRebootTimeout inside power management start flow:

1. Set host status to Reboot
2. Execute power management start
3. If start was successfully, wait until ServerRebootTimeout interval pass
4. Set host status to Maintenance or NonResponsive (depending of a way how StartVdsCommand was invoked)

Verified on 4.1.2-1
