Physical Hardware Configuration
HP-UX version 11.00.03 Administering Fault Tolerant Hardware 5-5
Continuum Series 400/400-CO Hardware Paths
Figure 5-3 illustrates a sample physical hardware configuration for a Continuum
Series 400 or 400-CO system. Each device in Figure 5-3 represents a physical node
on the system. Each connecting line represents a physical connection. The main
system bus (GBUS) connects the two suitcases with the two card-cages.
Each card-cage has eight slots (numbered 0–7) with the following characteristics:
■ A PCI bridge card (K138), which provides the connection between the system
bus and the PCI bus, is always in slot 0. The PCI bridge card includes a slot for
the flash card. The flash card locations are 0/2/0/0.0 and 0/3/0/0.0.
■ A SCSI I/O controller (U501), which provides support for the internal disks
and a port for an external tape or CD-ROM drive, is always in slot 7. Because
each SCSI controller has three ports, there are three addresses per card
(0/[2|3]/7/[0|1|2]). The attached disk, tape, and CD-ROM devices do not
have physical addresses, but they do have logical addresses (see “Logical SCSI
Manager Configuration”).
■ The remaining slots can contain other (optional) PCI cards. Figure 5-3
illustrates the presence of two additional PCI cards in each card cage:
T1/E1 cards (U916) reside in card-cage 2 at addresses 0/2/3/0 and 0/2/5/0,
respectively.
PCI Nexus Refers to the K138 PCI bridge card and its associated
resources. (LSM for SCSI ports or LNM for LAN ports is
the corresponding logical nexus.)
Logical Device Addresses
LMERC Nexus Refers to the CPU, memory, and console controller port
resources. (PMERC for CPU/memory or RECCBUS for
console ports is the corresponding physical nexus.)
LSM Nexus Refers to the logical SCSI manager and its associated
resources. (PCI or HSC is the corresponding physical
nexus.)
LNM Nexus Refers to the logical LAN manager and its associated
resources. (PCI or HSC is the corresponding physical
nexus.)
CAB Nexus Refers to the cabinet and its associated components.
