This provides us with an idea of types of devices (Sequential ~ Tape, Random ~ Disk)

connected to our system. This information, combined with the card types, gives us the

basic information needed to conﬁgure the system. Note that these devices are not SCSI

Multi-LUN devices; therefore, this output does not show the implied LUN value of ZERO

for each of these devices. The MPE/iX conﬁguration addresses of these devices would have

“.0” appended to them.

One piece of conﬁguration data that is missing is the actual hardware device Ids. At this

time the only source for this information is the ISL utility, ODE MAPPER2. MAPPER2 is

the 64-bit version of the MAPPER program used for previous HP e3000 platforms. For

more complete information on ODE MAPPER2, please see the MPE/iX System Software

Maintenance Manual for this Release. It is highly recommended that your conﬁgured

device Ids match the actual device Ids returned by ODE MAPPER2. For the purposes of

this article we’ll assume some arbitrary but legal device Ids.

The next part of your conﬁguration must be done while the system is “up” and running

MPE/iX.

New Boot Messages for N-Class (and A-Class):

Early in the system boot code, MPE/iX will scan possible hardware locations to determine

what I/O adapter cards are present in the system. The code will indicate the presence of

I/O adapter cards using “+” or “*”. The “+” indicates the presence of a PCI Device with a

single PCI function; the “*” indicates the presence of a PCI Device with multiple functions:
