HP-UX version 11.00.03 Administering Fault Tolerant Hardware 5-9
Logical Hardware Configuration
The system maps many physical hardware addresses to logical hardware devices.
The following major logical device categories are defined for Continuum systems:
■ the logical communications I/O processor
■ the logical cabinet
■ the logical LAN manager (LNM)
■ the logical SCSI manager (LSM)
■ the logical CPU/memory
Logical addresses are defined by the initial hardware address, 11 (communications
I/O), 12 (cabinet), 13 (LNM), 14 (LSM), or 15 (CPU/memory). Table 5-2 describes
the logical hardware categories.
The following sections describe the addressing scheme for each logical device.

Device Description Address

communications
I/O
A virtual mapping scheme used for
configuring communications I/O
adapter cards. (This category is for
earlier Continuum systems; it is not
used in Series 400/400-CO systems.)
11/...
logical cabinet A pseudo-device mapping scheme
used to address cabinet components.
12/...
logical LAN
manager (LNM)
A virtual mapping scheme used for
configuring LAN interfaces.
13/...
logical SCSI
manager (LSM)
A virtual mapping scheme used to
address devices on a logical SCSI
bus. A logical SCSI bus consists of
one or two SCSI controller ports
connected to a common physical bus.
14/...
logical
CPU/memory
A virtual mapping scheme for the
CPU, memory, and console ports.
