I am trying to create a device file for a Surestore tape library. The deivce file is used to move the robotic arm. what is the command for this?

0/7 ba Local PCI Bus Adapter (782)
0/7/0/0 ext_bus SCSI C87x Fast Wide Differential
0/7/0/0.0 target
0/7/0/0.0.0 tape QUANTUM DLT8000
0/7/0/0.6 target
0/7/0/0.6.0 unknown HP C7200-8000
0/7/0/0.7 target

mknod command.
but what is the proper syntex?

mknod /dev/robot

First you must include the driver (schgr) into the kernel, after the reboot you have your device file.




Currently you don't have the driver installed.

Look:

autoch 9 0/1/0/0.2.16.255.0.0.0 schgr CLAIMED DEVICE HP
C7200-8000
/dev/rac/c114t0d0

And now the changer command:

#mc -p /dev/rac/c114t0d0 -r IDSM
MT_slot_1 EMPTY
IE_slot_1 EMPTY
IE_slot_2 EMPTY
...

Hi Matthew,

You don't need to use mknod command until or unless you have manually removed the device file.

As Torsten specified, first you should include the driver for robotic arm into the kernel if it is not already included.

If it is already included, you either reboot the server or just run "insf -e" command which creates the necessary device files for you.
