The server with the two LPAR partitions were shut down due to a electric maintenance. I tried to start the partitions but I was having this problem:
hscroot@localhost:~> chsysstate -r lpar -m 10D400C -o on -n LPAR1
Unable to lock the Service Processor. Perform one of the following steps: (1) Check serial cable connection; (2) Check if another Console is communicating with the Service Processor; (3) Perform the Release Lock task; (4) Perform Rebuild task to re-establish the connection.
I tried again and I got a different error.
hscroot@localhost:~> chsysstate -r lpar -m 10D400C -o on -n LPAR1
Command sent to Service Processor failed. Error Response 4.
To reboot the IBM HMC, type the command below
hscroot@localhost:~> hmcshutdown -t now -r
Broadcast message from root (Sun Jun 6 08:35:38 2010):
The system is going down for reboot NOW!
I had problems with the reboot and asked to power off and power on the HMC. After that I had no more problems.
Resetting an LPAR on a Power4 system
First you need to check some information for your system on the HMC. Issue the command vtmenu to get the managed system ID and the names of the partitions
hscroot@localhost:~> vtmenu

Bye.
On this example I tried to soft reset the partition called MANUFACTURING
hscroot@localhost:~> chsysstate -m 108F19C -r lpar -n MANUFACTURING -o reset
Since it didn’t work out as expected, I decided to power off the LPAR
hscroot@localhost:~> chsysstate -m 108F19C -r lpar -n MANUFACTURING -o off
hscroot@localhost:~> vtmenu

I turned the partition on and after that it worked flawlessly
hscroot@localhost:~> chsysstate -r lpar -m 108F19C -o on -n MANUFACTURING

Download IBM WebSM for HMC v6
To download the Web Based System Manager client you simply open a browser window and type the URL http://<ip address of your HMC>/remote_client.html.
To check the version of your HMC, type lshmc -V
hscroot@localhost:~> lshmc -V
“version= Version: 6
Release: 1.2
HMC Build level 20070201.1
MH00985: Miscellaneous fixes for HMC V6 (04-15-2007)
“,”base_version=V6.1.2
“
The Hardware Management Console v7 has web access, so you don’t need to install a client to use it.
