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
On a system with a large LUN configuration, HP-UX cannot build device files on all LUNs.
Enter insf
Example
# ioscan -fn
Class
bc
fc
lan
fcp
ext_bus
disk
disk
ext_bus
target
ctl
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 might be configured properly.
See 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
