Configuring Robotic Controls

Example 2

Assume the robotic control for an Exabyte 10i tape stacker (TS8) is on a built-in SCSI bus

at SCSI ID 3, LUN 0. Also assume that an ioscan -f verifies that the SCSI ID is 3 and

shows that the Instance number for the robot’s SCSI bus is 1.

The commands to create the device file are

cd /dev/sctl

/usr/sbin/mknod c1t3l0 c 203 0x013000

This creates the following device file, which you specify to Media Manager:

/dev/sctl/c1t3l0

Example 3

1. Use the ioscan -f command to get information on the SCSI bus and the robotic

control.

With fibre channel and SCSI muxes the hardware paths are a bit longer. If you use the

bus H/W Path as a mask and apply it to the other hardware paths for devices on that

bus, you are left with SCSI ID.SCSI LUN for the device.

This example has a bus with H/W Path of 0/0/0.8.0.0.0, which has an instance

number (I column) of 3. Applying the mask shows a DLT 7000 drive at SCSI ID 0,

SCSI LUN 0 and a STK 9740 robot at SCSI ID 1, SCSI LUN 0 also on this bus.

When configuring the robotic device file for the STK 9740 robot, you would use

controller=3, target=1, and lun=0. To enable the passthru path for the Quantum DLT

7000 drive, you would use controller=3, target=0, and lun=0.

2. The commands to create the device file for the robotic control are as follows:

cd /dev/sctl

/usr/sbin/mknod c3t1l0 c 203 0x031000

These commands create the following device file, which you specify to Media

Manager during configuration of the robotic control:

/dev/sctl/c3t1l0
