Booting a Partition to the ISL Prompt
You can stop a partition’s booting at the Initial System Loader (ISL) in
order to interact with 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.
BCH Use the following procedure to boot a partition to the ISL prompt.
On HP Superdome 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
Superdome servers by each partition’s BCH interface.
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.
Step 1. Log in to the Superdome complex’s GSP, access the partition’s console,
and access the BCH main menu.
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.
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.
You can perform this task using the BCH interface.
