HP-UX operating system.
3. Enter the device data for each disk array device in a table. See “Path
worksheet” on page 56.
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.
Example
5. Verify that the SCSI TIDs correspond to the assigned port address for
all connected ports (see mapping tables on page 57 in Appendix B, for
values). 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 Appendix B (page 57), set a
SCSI bus
instance number Hardware path SCSI TID LUN File name
