Booting an nPartition to the ISL Prompt
When you issue the BCH interface’s BOOT command you can stop an
nPartition’s booting at the Initial System Loader (ISL) interface in order
to interact with the ISL prompt.
To exit ISL and return to the BCH interface, enter the EXIT command at
the ISL prompt. For help enter HELP at the ISL prompt.
Normally you will not need to access ISL unless you need to use the
Secondary System Loader (hpux).
For details about ISL, see the isl (1M) manpage. Details on the
Secondary System Loader (hpux) are in the hpux (1M) manpage.
NOTE On HP nPartition servers many of the ISL commands are not supported.
For example, AUTOBOOT, AUTOSEARCH, and PRIMPATH are not
supported at ISL.
These and other features are instead supported on HP nPartition servers
by each partition’s BCH interface.
BCH This procedure (BCH BOOT command, and reply y to “stop at the ISL
prompt”) boots a partition to the ISL prompt.
Step 1. Log in to the server complex’s service processor (GSP or MP), access the
partition’s console, and access the BCH interface.
From the partition console you access the partition’s BCH interface. If
the partition is not at the BCH interface you must either boot the
partition or shut down HP-UX to return to the BCH interface.
If an nPartition is configured to automatically boot HP-UX, you must
interrupt the boot process before HP-UX boots, then manually boot
HP-UX using the BOOT command (in the next step) to access the ISL
interface on the partition.
Step 2. Boot the desired device using the BCH interface’s BOOT command, and
specify that the partition stop at the ISL prompt prior to booting (reply y
to the “stop at the ISL prompt” question).
