Creating the device files

If the device files were not created automatically when the system was restarted, use the insf
command in the /dev directory to create the device files. After this command is executed, repeat the
procedures in
device files and driver.
Example
# insf -e
insf: Installing special files for mux2 instance 0 address 8/0/0

Failure of the insf
If the device files for the new disk array devices cannot be created automatically, you must create the
device files manually using the mknodcommand 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
d stands for device
The numbers x, y, and z are hexadecimal.
