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.
