Description Reid Wahl 2021-01-27 09:43:23 UTC

Description of problem:

Add a diag action similar to the one used with fence_ipmilan. This action should send an NMI, which can cause the system to panic and dump a vmcore if the kernel tunables are set appropriately.

Hopefully, this will only require adding `'diag': "Nmi"` to the action dict and adding "diag" to the device_opt list.

Reference:

I do not have an environment with which to test fence_redfish.

How reproducible:

Always

-----

Steps to Reproduce:
1. Run `fence_redfish` with valid credentials and the `-o diag` option.

Actual results:

Expected results:

fence_redfish successfully sends an NMI to the target system.
