Starting HP-UX
Bringing the V-Class server to a usable state involves two systems and
their hardware and software. This section provides a brief overview of
the process; for complete instructions, see Managing Systems and
Workgroups. Additional information is contained in the V2500/V2600
SCA HP-UX System Guide. This section describes:
A V-Class server consists of two systems:
• System Support Processor (SSP)
• Boots the V-Class server
• Monitors the V-Class server for hardware errors
• Debugs a hung system
• Runs HP-UX
• V-Class cabinet
• Hosts OpenBoot PROM (OBP) software
• Runs HP-UX
The main firmware interface, the OBP boot menu, provides a
straightforward interface for managing a system before HP-UX boots.
The OBP menu is available through the V-Class console interface.
In multiple-cabinet V2500/V2600 SCA systems, each V2500/V2600
cabinet runs its own copy of the firmware. Normally during booting you
only need to interact with the OBP menu on cabinet ID 0, which serves
as the “monarch” or master cabinet. The other cabinets (IDs 2, 4, and 6, if
present) run the same set and version of firmware, but are considered to
be “serf” cabinets under control of the monarch cabinet once OBP starts.
IMPORTANT Only I/O devices on cabinet ID 0 may be used as the boot device for a V-
Class server. Likewise, only logical volumes that reside entirely on
cabinet ID 0 may be used as the boot device.
