Accessing an nPartition Console and
BCH Interface
Each nPartition has its own Boot Console Handler (BCH) interface that
provides you a method for interacting with the nPartition 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 Accessing nPartition
Console and BCH Interfaces [Service Processor] below for a detailed
procedure.
On nPartition servers, each nPartition’s BCH interface is available
through the nPartition’s console before HP-UX has booted. The BCH
interface enables you to manage the nPartition’s HP-UX boot process
and to configure various boot-related settings.
NOTE Always login 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 login 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).
Accessing nPartition Console
and BCH Interfaces [Service Processor]
The following procedure (login to service processor, select Console menu,
select an nPartition) accesses an nPartition’s console and BCH interface
using the server complex’s service processor.
Step 1. Login to the service processor (the GSP or MP) for the nPartition’s server
complex.
You can connect to the service processor using a direct physical
connection, or using telnet for a remote connection.
