I am having issues setting up my power systems to use v term on HMC. I get a error that the system is reserved for serial connection. This is understandable cause they were setup via serial. They are 1 Lpar machines , and have now been setup to connect to HMC.

This is the IBM technote that I followed but still no luck. I removed serial and only had HMC connected , but still couldn't connect VIA vtmenu .

Any advice ?
Technote (troubleshooting)

Problem(Abstract)
System p is newly attached to a hardware management console (HMC) and the server property for manufactoring default configuration (MDC) is false. The vterm console works in hardware mode (i.e. SMS and for displaying hardware parameters when lpar is activating). However, the vterm does not display login prompt after AIX has been booted.

Symptom

Cause
AIX was installed on system p server when it was attached to an async console prior to attaching system to HMC.
Resolving the problem
To reconfigure the AIX's console device to use the new hardware connection you will need to do the following:
Either telnet (or SSH) into the server if networking had been configured or boot into a maintenance shell and run following procedure.

The procedure will completely remove vty0, vsa0 (and any other vty or vsa device) and syscons objects from the ODM and allow them to be recreated by AIX when system reboots.

Once telneted in or in a maintenance shell, as root execute the following:

1. odmdelete -q name=vty0 -o CuDv

1. odmdelete -q name=vty0 -o CuDv

1. odmdelete -q name=vsa0 -o CuDv

1. odmdelete -q name=vsa1 -o CuDv

1. odmdelete -q attribute=syscons -o CuAt

1. bosboot -ad /dev/ipldevice <---- customer hung trying to run this

command

1. sync

#reboot

When system comes up it should reconfigure vsa0 and vty0
and since we removed "syscons" from ODM it should prompt
you to select a terminal. This time, the only device
connected for a console should be the HMC's vterm.

You should messages similar to following when LPAR is booting back up:

---

• Please define the System Console. *********

Type a 1 and press Enter to use this terminal as the
system console.

good day all

thank you for the responses , sorry I never updated the forum but I got it working
http://unix.derkeiler.com/Newsgroups/comp.unix.aix/2009-05/msg00015.html

This process fixed the issue for a one Lpar machine , not sure if you want to use this for a machine running more than one Lpar , if you do just be careful and make a backup of your profile before initializing :)
