Configuring Robotic Controls

If the devices do not exist, you can create device files by using the mknod command as

follows. See the scsi_ctl(7) man page.

mkdir /dev/sctl

cd /dev/sctl

/usr/sbin/mknod c

CONTROLLER

TARGET

LUN

c 203 0x

IITL

Where:

◆ CONTROLLER is the Instance number of the controlling bus. The Instance value is

displayed in ioscan -f output under column I of the controller entry (ext_bus in

the Class column).

◆ TARGET is the SCSI ID of the robotic control.

◆ LUN is the SCSI logical unit number.

◆ II are two hexadecimal digits that identify the controlling bus interface card by its

Instance number (same as controller).

◆ T is one hexadecimal digit representing the SCSI ID.

◆ L is one hexadecimal digit representing the SCSI LUN.

Using ioscan With sctl Robots

If the robotic control has its own SCSI ID, it has an entry similar to the following:

Class I H/W Path Driver S/W State H/W Type Description

===================================================================

unknown -1 2/0/1.1.0 unknown UNCLAIMED UNKNOWN LAGO SYSLS-340L

The Class, I, and Driver columns may also have invalid information. In these instances

the robotics are correct, but ioscan returns invalid information.
