Subject: [Users] request for WOL
I would like to request Wake on LAN support be added to the Power
Management interface. It seems like a good fall back for anyone
who
doesn't have proper power management capabilities.
Fencing needs to reboot a node, WOL would only wake it up if it was
suspended.

But it could issue the reboot command via SSH no?
No. Fencing is used when the node is not responsive, if we could ssh into it
then it's unlikely we'd be fencing it.
When a node isn't responsive we need a mechanism to reset it but also confirm
that it's been dealt with, so using IPMI (which is in nearly all servers
today, even whitebox), iLO, DRAC, IMM, etc allows us to connect to the
management controller reboot it and confirm that it's been reset.
Other approaches we can take involve extending our use of sanlock.
I was also interested in WOL and curious as to why it wasn't in there
already. WOL allows the system to go into standby for power
management (less desirable than Off, but standby could return to
actually more desirable than off in many cases - for example in the cluster
policy we could put a node into powersaving mode and more quickly resurrect it
when required.
That's been on the list for a long time - just needs patches .
service faster). For poweroff, the shutdown command could be passed
via SSH, but the system would have to prompt that manual booting
would be required. Unless the system supports boot on WOL request.
