Re: Requests from IBM-tech. Do not know what/how to handle

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.

HTH.
