The messages seen when booting an A-Class system will be an abbreviated form of the

above as the A-Class systems have fewer PCI Buses. The remainder of the system boot

messages will be the same as seen on existing platforms on current MPE/iX Releases.

Conﬁguring SCSI Devices using SYSGEN on N-Class Systems

The process followed to conﬁgure SCSI Devices on these new Device Adapter Cards is the

same as the process conﬁguring of SCSI Devices on existing HP e3000 9XX Systems. The

main difference is that various path elements represent different hardware components

than on existing HP e3000 9XX systems; these new hardware devices require different

software drivers.

For the following examples we will assume that we are using the same system information

presented in the preceding examples. These examples will show the conﬁguration of an

internal disk drive (as LDEV 1), an external tape drive (as LDEV 7) and cover the special

cases of the System Spooled Printer (LDEV 6) and System Streams Devices (LDEV 10).

The conﬁguration of LDEV 20, the System Console, and other Data

Communications/Networking hardware devices, will be covered in separate articles in this

Communicator.

We’ll start by conﬁguring LDEV 1 on the internal system disk at path address 0/0/2/0.6.0.

Recall from our previous explorations that this path represents a “random access media,”

e.g. a disk, and that it in on the Core I/O Embedded A5159A (DP HVD). We’ll choose the

disk Id of HPC2490WD as this is a supported “Fast/Wide SCSI” (HVD) disk (you may use

this Id too, though it is recommended that you use the Id obtained from ODE MAPPER2).

As with existing HP e3000 systems, you must build up a set of paths by conﬁguring each

path element separately starting with the left-most element. To review the hardware

path “0/0/2/0.6.0” can be interpreted as:

System Bus Location / Local Bus Number / PCI Device / PCI Device Function . SCSI Target

. SCSI LUN

We start by conﬁguring System Bus Location equal to zero (“0”). We then conﬁgure Local

Bus Number equal to zero (“0”), PCI Device equal to two (“2”), and PCI Function equal to

zero (“0”). The System Bus entry, Local Bus entry and PCI Device entry all have new and

unique conﬁguration identiﬁers. The conﬁguration of SCSI devices is accomplished with

the same exact steps as are followed in MPE/iX 6.5 on existing HP e3000 systems.
