Hello,
what is considered the best way to shutdown and restart an hypervisor,
supposing plain CentOS 7 host?
For example to cover these scenarios:
1) update host from 4.0 to 4.1
2) planned maintenance to the cabinet where the server is located and take
the opportunity to update also OS packages
My supposed workflow:
- put host into maintenance
- yum update on host
- shutdown os from inside host (because from power mgmt it is brutal power
off / power on)
--> should I get any warning from web admin gui in this case, even if the
host was in maintenance mode?
- power mgmt -> start from webadmin gui
(or power on button/virtual button at host side?)
Would be advisable to put inside power mgmt functionality some logic about
os mgmt, so for example, if action is restart, first try to shutdown OS and
only in case of failure power off/power on?
Thanks in advance,
Gianluca
I see that one of the new features of 4.1 is Host restart through SSH
Power Mgmt --> SSH Mgmt --> Restart
How does it fit in question above?
Can I choose this way after having run "yum update" on host?
Thanks
