To verify device recognition:
1. Log in to the system as root.
2. Display the device data to verify that the system recognizes the newly installed devices on the
disk array. Use the ioscan –fn command to display the device data.
On a system with a large LUN configuration, HP-UX may not build device files on all LUNs. Enter
insf –e to build all missing device files.

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 Appendix A.
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:
c x t y d z
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.
