Looks like they f'd up at the factory and set a machine I want to run
in SMP mode up as a LPAR setup. When I hook a laptop up the serial
port and try to login to the SP to change the setting, after I hit
enter on the user name, the system scoots by and tries to boot up.
I want to run this in SMP mode, because I don't have an HMC, which
means that the machine won't boot up in LPAR mode.
Has anyone seen their P570 exhibit this kind of behaviour? How did you
fix it?
We have tried almost every combination of port speed and parity etc.
and the best we can do is get the machine to start up to the login
prompt for the SP, and then when you try to type in the password you
get garbage characters, and the system goes on and tries to boot.

Having the same problem on 4 servers.

Wrong serial cable?

The p5 systemsare alwaysin LPAR mode even if there is no HMC. In this
case it is an default LPAR with all resources.

If you get garbage the connection is ok but the speed is wrong. Default
speed on the p570 should be 19200.

You can also try the ethernet ports:

The P570 is an install by IBM, as opposed to customer setup, machine
presuming that it's new. Your CE should be able to login and fix
this, or reset the SP and fix it, or if all else fails order a new SP
and fix it that way.

The P5 "SMP" mode is really an LPAR which sees all the system
resources, it is different that the P4 machines were. But without a
HMC connected, when you hit the power on button, it should power on to
a logon prompt at the serial port eventually.

The serial interface for the SP on P5 machines is a little flakey, and
the com speed is 19.2 instead of 9600. It should work with a standard
null-modem cable.

Hope this helps, have fun
