Can't use mc command for HP Surestore tape autoloader model 1/9

Now I use autoloader 1/9 on HP-UX 11i. I can use tar to this tape drive (I use command on autoloader to control changer) . But now I want to control this changer by mc command because I need to change tape from remote, but I can't.
When I use mc command 'mc -p /dev/rmt/1m -r DS'. This error messages occur 'Error: 0x5 Illegal : 0x2400 Invalid Field in command descriptor block. What's mean? How I can solve it for use mc command?
And I use command ioscan. The DLT drive is recognized but the changer is not.
output:
unknown -1 1/0/0/0.1.0 UNCLAIMED UNKNOWN HP C7145-80 00
Is it need any driver? If,yes. Where I can find it? What does I need to do? And this problem relate with first problem or not?

Hi,
You need to add the sctl driver to the kernel and create a devicefile for the robotics. Here is an example from one of our systems:
crw-rw-rw- 1 root sys 203 0x006000 Jul 17 2002 /dev/picker2
