Second asked to “unassign” the adapter. I have no clue how that is done.
VRYCFG is not for adapters…

You can do that from the HMC, if the adapter is set to be "desired" and not "required" by the partition. However, if the adapter is a RAID controller, it might be used for disk drives. If you do "unassign" it, the partition will loose those disks and will freeze, so be very careful.

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. Checked if it was possible to access through
the Navigator ut apparently not. Nothing in the ACS activities either. Saw
something about a web interface something like the navigator (link shown in
youtube video) but that did not work either. Is the HMC a device such as a
PC physically connected to the machine or is there some kind of setup that
is missing?

The HMC (standing for Hardware Management Console) is a dedicated device (an IBM x86 or Power based device or a specific Virtual Machine managed by virtualization engines such as VMWare, running a specific and closed version of Linux) used to manage (create/change/start/end) partitions and servers (start/end/update). It is a completely distinct stuff than the server and the partitions.

For both 2 and 4 bullets, you need an access (a user profile) to the HMC (its IP address) from your workstation. Bullet #2 can be achieved with a web interface, while bullet #4 will be achieved with an ssh interface. PEDBG how-to is provided here by IBM but I can understand  that if you are not familiar with those concepts, it might be in some way an intimidating experience.
