PEDBG is done from the command line on the HMC. IBM has excellent
instructions on how to do that which they can provide.

I am not familiar with doing any hardware work on the platform.

You're brave to try anyway. :-)

Second asked to “unassign” the adapter. I have no clue how that is done.
Fourth asked to create something called PEDBG using the HMC. This task –
(together with the “unassign” thing) is where I am stumped. I have never
worked with the HMC in my life.

My guess is that also the "unassignment" is to be done from outside the
OS, thus the HMC.

Is it not an option to have IBM support guide you through the processes?

Is the HMC a device such as a PC physically connected to the machine or
is there some kind of setup that is missing?

In general, a HMC is a "device" (hardware in earlier times, today
available as virtualized "appliance" also) to manage mostly the hardware
side of IBM machinery, including LPARs.

Any hint about how to perform task 2 and 4 w/o travelling to the client
site would be really helpful!

You can connect to the HMC from a web browser, if it's configured
accordingly. No need to go there.

You can't tick "open console window" on a remote connection, but you can
point a 5250 emulator to TCP Port 2300 of the HMC and obtain console access
through interactive questions/answers. Hope you have access to the required
logon credentials.
