Comment 15 for bug 2004661

@Igor, we have exactly the same behaviour on HP ProLiant DL380 Gen11

I know we can change the boot order (next boot order) while the machine is off. The only restrictions is during POST and this is exactly why the power management failed via redfish from time to time (quite often in fact)

The problem is that power_query is unable to send back details if we are in POST or not. I guess the implementation should do a retry on the PXE boot order https://github.com/canonical/maas/blob/de2288e04a9ad6fee7dd8954f6502d754f2ef280/src/provisioningserver/drivers/power/redfish.py#L272

Maybe in the spirit of what is done for ipmi (which we don't want to use as it is not enabled over LAN by default in ILO) : https://github.com/canonical/maas/blob/de2288e04a9ad6fee7dd8954f6502d754f2ef280/src/provisioningserver/drivers/power/ipmi.py#L488

We are using maas 3.4.2
