38 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX

Creating the device files

If the device files were not created automatically when the system was

restarted, use the insf –e command in the /dev directory to create the device

files. After this command is executed, repeat the procedures in the previous

section

(page 36) to verify new device recognition and the device files and

driver.

Example

# insf -e

insf: Installing special files for mux2 instance 0

address 8/0/0

: : : :

Failure of the insf –e command indicates a SAN problem.

If the device files for the new disk array devices cannot be created

automatically, you must create the device files manually using the mknod

command as follows:

1. Retrieve the device information you recorded earlier.

2. 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.

1 2 ... 31 32 33 34 35 36 37 38 39 40 41 ... 81 82
