cannot set one-time-boot on M8 using sdk

[dancanran]

When Power-cycle an M8 blade for it to boot to PXE (via API), it keeps booting to HD and not to PXE.
But when doing the same manually, it is booting to PXE (therefore no network connection issue with our PXE server or a PXE server issue).

The code we are using wasn’t changed for years now and was working fine. I’m not sure if the issue we seen now is specific to M8 blades or a global issue as I’m not sure if we recently installed a UCSX blade other than M8.

The relevant code is this:

filter1 = "Name eq '" + host_location + "'"
blade_setting_mo = call_ucsx.compute_api_instance.get_compute_server_setting_list(filter=filter1)
if blade_setting_mo is not None and len(blade_setting_mo.results) > 0:
blade_setting_moid = blade_setting_mo.results[0].moid
call_ucsx.compute_server_setting.admin_power_state = "PowerCycle"
call_ucsx.compute_server_setting.one_time_boot_device = "pxe"
update_response = call_ucsx.compute_api_instance.update_compute_server_setting(blade_setting_moid, call_ucsx.compute_server_setting)
for i in update_response.server_op_status:
if 'ServerPowerCycle' in i.workflow_type:
return True

When testing it manually, I do get confirmation about the power-cycle, see here:

I've reproduced the issue on a UCSX-210C-M8 running FW bundle 5.4(0.250037). I've filed an internal issue and will update here when the defect is being worked.
