HP XP1024 System Configuration Manual page 24

In the example:
• HP OPEN-9 device: SCSI bus number = 14/12, bus instance = 6, SCSI
target ID = 0, LUN = 0.
• HP OPEN-9*2 device: SCSI bus number = 14/12, bus instance = 6, SCSI
target ID = 0, LUN = 1.
• If UNKNOWN is displayed for a disk, the HP 9000 system may not be
configured properly. Refer to the HP documentation or contact HP customer
support for assistance with the HP 9000 system or the HP-UX operating
system.
3. Enter the device data for each disk array device in a table. See
4. Construct the device file name for each device, using the device information, and
enter the file names in your table. Use the following formula to construct the device
file name:
cxtydz
where
x = SCSI bus instance number
y = SCSI target ID
z = LUN
c stands for controller,
t stands for target ID, and
d stands for device. The numbers x, y, and z are hexadecimal.

5.
Verify that the SCSI TIDs correspond to the assigned port address for all connected
ports (see mapping tables in
If so, the logical devices are recognized properly.
If the logical devices are not recognized properly:
• Check the AL-PA for each port using the LUN Manager software.
• If the same port address is set for multiple ports on the same loop (AL with
HUB), all port addresses except one changed to another value, and the
relationship between AL-PA and TID does not correspond to the mapping
given in
for each port, reboot the server, and then verify new device recognition
again.
