Subject: [Users] oVirt with UPS Shutdown Software
Hi guys,
I've looked around briefly and can't seem to find much info on this,
so please excuse me if this has already been asked/documented.
I have a UPS with SNMP support and I started installing the
management
software(IPP) that it comes with and then it occurred to me that the
shutdown sequence of servers with oVirt 3.1 would be quite critical.
Is there any documentation on shut down sequences or does anyone know
what the recommended way of handling power failures are?
My thinking is that when a power failure is detected by the UPS
software running on the ovirt-engine machine, the VM's need to be
shutdown gracefully, and then the data center needs to be put into
maintenance, before the hosts are eventually shutdown, and then
finally the ovirt-engine needs to be halted.
sounds right to me:
shutdown the vms,
put data-center to maintenance (actually means put all domains to maintenance - i guess
this part is nice to have but not must)
then put hosts to maintenance (not sure you mentioned that)
then you can shutdown any server in any order.
Any thoughts or ideas/suggestions on the above, can the ovirt-engine
somehow be told to shutdown the VM's and hosts etc?
well writing a script to do that shouldn't be hard using the API,
but the question how to trigger it? (i'm not familiar with the UPS software
capabilities)
Thank you very much.
Regards.
Neil Wilson.
