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

Ake,
Our data centers are about that distance from me.  I can do stuff remotely
and frequently do.  The HMC is a blessing.
The GUI options may be different based on the version of HMC you are
running. Currently they are on a version of 10 but I bet there are a lot of
versions 8's still out in the field.  This may be why you are having a
tough time finding the exact click on the GUI.  The differences between the
older and the newer versions are drastic.  Some people were dragged kicking
and screaming to the new versions and only did so when the older versions
would no longer support the newer Power systems.  It was a shock to me too
but I find the newer version quite better.

I 'assume' you have iACS.  On iACS go into Management, System
Configurations.  Pick your system.  Click the Console tab.  Select HMC 5250
console.  Put in the host name/IP address of your HMC.  Once you've done
this it's quite easy to use iACS to click on Console, 5250 console.  Now
click on Hardware Management Interface.  Put in the host name or IP address
that your HMC uses to talk to your Power system.  Also call your HMC
Management port. This will NOT be the same IP address you normally use to
connect to the system.
If you do not know the name or IP address of your HMC Management port but
you have access to your HMC you can get it from the HMC via General
Settings for the system (not your lpar of IBM i).  System name and IP
address.
You know, I kinda think I got off on a tangent...

pedbg may be easier from a putty client SSH session attached to your HMC.
You can search for hmc pedbg command line or some such thing for that.
Clue:  Why didn't the hardware guy have you use the option in MGTOOLS to
get a pedbg???  SYSSNAP ... COLPEDBG(Y) HMCLOC(MYHMC) HSCPEPWD() Q(4)
Maybe because you're new he thought it would be easier for you to use the
other steps to ensure you created the user hscpe and have the remote
connection allowed to your hmc turned on by doing the manual steps.

I'm not sure about the "unassign" and I hope that translated well.  There
are ways to reboot an adapter without IPLing your system.  You have to be
real careful that you don't have disks attached to it and stuff but I do
this frequently for things like tape libraries.  All of our stuff is
virtual but we still have to IPL the virtual adapter on occasion.
  Once you gain experience it's pretty easy to be sure.  For example:
WRKMLBSTS
8=Work with description
5=Display
Record "Resource name"
Vary it off.
WRKHDWRSC *STG (your option may differ.  It would help if you said what the
adapter does)
Resource        Type-model  Status
CMB04            6B25-001   Operational
  DC04           6B25-001   Operational
  KDVLVTL        3584-032   Operational
These contain only the tape device and no drives, etc.
CMB04 is the IOP.  DC04 is the IOA.

STRSST
1. Start a service tool
7. Hardware service manager
3=Concurrent maintenance
3.  Locate resource by resource name.  Use the IOP or the IOA
6=I/O debug
I normally do these in order
3. Reset I/O processor
4. IPL I/O processor
Exit sst.
Vary on the device, maybe with the reset option
VRYCFG CFGOBJ(KDVLVTL) CFGTYPE(*DEV) STATUS(*ON) RESET(*YES)
 and hope for the best
