Determining SCSI Devices Connected to Your System
The N-Class system has a built in function that will search for SCSI devices attached to the system. This
function is available on the Main Menu as the Search command. It is to be noted that this Search command
is helpful only in finding the devices attached to SCSI adapter cards and not for the devices attached to Fibre
Channel adapter cards. The procedure to determine FC devices connected to FC adapter cards is covered in a
later section.
Console Display #4:
Main Menu: Enter command or menu > sea
Searching for potential boot device(s)
This may take several minutes.
To discontinue search, press any key (termination may not be immediate).
Path# Device Path (dec) Device Path (mnem) Device Type
----- ----------------- ------------------ -----------
P0 0/0/1/0.2 extscsi.2 Sequential access media
P1 0/0/2/0.6 intscsia.6 Random access media
P2 0/0/2/1.6 intscsib.6 Random access media
P3 0/8/0/0.8 Random access media
P4 0/12/0/0.4 Random access media
P5 0/12/0/0.3 Random access media
P6 0/12/0/0.2 Random access media
Main Menu: Enter command or menu >
Note that the Search command shows the FC card 0/8/0/0 as “0/8/0/0.8 Random access media”. This is not an
actual FC device path but just a hint that there could possibly be random access media devices under this
card. We will see later how to identify the FC devices connected to the card.
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. This will
cover the detailed steps for configuring Fibre channel adapter card and Fibre channel devices. The
configuration of SCSI devices on PCISCSI adapters is accomplished with the same exact steps as followed in
MPE/iX 7.0 on N- and A-Class HP e3000 systems and is not discussed here.
