Accessing a Partition Console and
BCH Interface
Each nPartition has its own Boot Console Handler (BCH) interface that
provides you a method for interacting with the partition before HP-UX
has booted on it.
You must access an nPartition’s console and BCH interfaces through the
server complex’s service processor (GSP or MP). See Service Processor
below for a detailed procedure.
On nPartition servers, each partition’s BCH interface is available
through the partition’s console before HP-UX has booted. The BCH
interface enables you to manage the partition’s HP-UX boot process and
to configure various boot-related settings.
NOTE Always log in to a server complex’s service processor from a tty (not
console) login session. You can check your current login terminal using
the who -m command.
Do not log in to a service processor from an nPartition console
connection. Any use of the ^b (Control-b) console exit sequence would exit
the original console login—not the subsequent console-based login to the
service processor—thus potentially stranding the console-based login (for
example, if it too were accessing a console).
Service Processor The following procedure (log in to service processor, select Console menu,
select a partition) accesses a partition’s console and BCH interface using
the server complex’s service processor.
Step 1. Log in to the service processor (the GSP or MP) for the partition’s server
complex.
You can connect to the service processor using a direct physical
connection, or using telnet for a remote connection.
