Tools for Managing Superdome Booting
HP Superdome servers support the following software tools for
configuring and managing partition boot settings.
For an overview of procedures that use these boot management tools, see
“Introduction to Boot and Reset Tasks” on page 222.
While these tools do overlap in some of the functionality they provide,
each provides unique capabilities. The primary tools for managing HP
Superdome booting are shown in the following list.
• Guardian Service Processor (GSP)—Users who have access to a
Superdome complex’s GSP menus can reset partitions, put partitions
into a ready-for-reconfig state, and TOC the partitions in the complex.
The GSP also provides power on and power off commands for power
cycling system hardware components.
• Boot Console Handler (BCH)—Each partition’s BCH interface
provides commands booting for HP-UX, rebooting the partition,
putting the partition into a ready-for-reconfig state, configuring
boot-related settings, and checking the partition’s hardware and
boot-setting configurations.
• HP-UX System Loaders (ISL and hpux)—When you issue the
BCH interface’s BOOT command to boot a device on the partition, the
boot process provides you the following option:
Do you wish to stop at the ISL prompt prior to booting?
(y/n)
Replying “y” (yes, do stop at ISL) allows you to interact directly with a
boot device’s Initial System Loader (ISL) and the Secondary System
Loader (hpux). You can list files that reside on the device, such as
kernel files in /stand, and can specify boot arguments to the hpux
loader.
Replying “n” (no, do not stop at ISL) skips the ISL prompt and
proceeds to boot HP-UX on the partition.
See the isl (1M) and hpux (1M) manpages for details.
