Verifying device recognition
Verify that the HP-UX system recognizes the new devices on the disk array.
If the SCSI paths were defined after the system is powered on, you must
halt and restart the system to allow the system to recognize the new
devices.
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.
Example
# ioscan -fn

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.
