This section describes how to set up the ETERNUS LT220 tape library.
Note
The SCSI-ID or LU for the robot or the drive of the ETERNUS LT library may differ depending on the model of the device or settings. For details, refer to the manual of the hardware or contact a Fujitsu Engineer (CE).
Disabling the st driver
Execute the ls command to display the device file.
# ls -l /dev/rmt/*[0-9] lrwxrwxrwx 1 root root 40 Feb 27 15:07 /dev/rmt/0 -> ../../devices/pci@16,2000/scsi@1/st@5,0: lrwxrwxrwx 1 root root 50 Feb 27 15:07 /dev/rmt/1 -> ../../devices/pci@1f,4000/FJSV,ulsa@3/st@1,0: ... |
Check the displayed device file to see if the st driver recognizes the LT220 device.
../../devices/pci@1f,4000/FJSV,ulsa@3/st@1,0:
1 2 3
1:"devices/pci@1f,4000/FJSV,ulsa@3" = This is the physical path name that indicates where the HBA is installed.
2:"st"= Indicates that the LT220 is controlled by the st driver
3:"1,0"= Hexadecimal display indicating "Target ID (LOOP ID),LUN" |
From these contents, the user can find out if the physical path is an HBA connected to the LT220, check whether or not the target ID (LOOP ID) and LUN information match the LT220 drive, and find out if the LT220 drive is controlled by the st driver.
Note
If the LT220 is not included in the drives controlled by the st driver, steps 3 to 5 below are not required.
If there are programs that access the drive, stop all those programs.
If the LT220 is controlled by the st driver, comment out the target definition that corresponds to the LT220 drive in /kernel/drv/st.conf.
Point
To comment out the target definition, insert "#" at the start of the part that matches the target ID (LOOP ID) and LUN of the LT220 drive.
Note
If the server has in-built drives, ensure that you do not comment out the definitions for the in-built drives.
Delete the device file of the LT220 drive that is controlled by the st driver.
The following is an example of how to delete the device file confirmed in Step 1 and 2.
# rm -i /dev/rmt/*
rm: remove /dev/rmt/0 (yes/no)? n
rm: remove /dev/rmt/0b (yes/no)? n
:
rm: remove /dev/rmt/1 (yes/no)? y
rm: remove /dev/rmt/1b (yes/no)? y
: |
Note
When executing the rm command, be careful not to accidentally delete other files.
Robot settings
Enter the Target ID of the LT220 robot in the /usr/kernel/drv/lb.conf file. Refer to the sample lb.conf file and enter the robot SCSI ID as the Target ID. In the following coding example, the SCSI ID is 0.

name="lb" class="scsi"
target=0 lun=0; |
Note
In the /usr/kernel/drv/lb.conf file, the "name" value is "lb" and the "class" value is "scsi".
For the "lun" value, check the set value for LT220 and set it accordingly.
Register the lb driver.

IBM Tape Driver settings
Verify the Target ID and LUN ID of the drive in the /usr/kernel/drv/IBMtape.conf file. However, these values are normally set during installation and usually need not be changed. Simply check the contents.

Creating a device file
Reboot the server.
# touch /reconfigure # /usr/sbin/shutdown -y -i6 -g0 |
After the server is rebooted, execute the ls command to display the device file (lb).
# ls -l /dev/rmt/?lb lrwxrwxrwx 1 root root 40 2 month 27 day 15:07 /dev/rmt/0lb -> ../../devices/pci@16,2000/scsi@1/st@5,0: lrwxrwxrwx 1 root root 51 2 month 27 day 16:50 /dev/rmt/1lb -> ../../devices/pci@1f,4000/FJSV,ulsa@3/lb@0,0:lb # |
Check the displayed device file to see if the lb driver recognizes the LT220 robot.
../../devices/pci@1f,4000/FJSV,ulsa@3/lb@0,0:lb
1 2 3
1: "devices/pci@1f,4000/FJSV,ulsa@3" = This is the physical path name that indicates where the HBA is installed.
2: "lb" = Indicates that the LT220 is controlled by the lb driver
3: "0,0" = Hexadecimal display indicating "Target ID (LOOP ID),LUN" |
From these contents, the user can find out if the physical path is an HBA connected to the LT220, check whether or not the target ID (LOOP ID) and LUN information match the LT220 robot, and find out if the LT220 robot is controlled by the lb driver.
Execute the ls command to display the device file (st).
# ls -l /dev/rmt/?st lrwxrwxrwx 1 root root 56 2 month 27 day 16:50 2st -> ../../devices/pci@1f,4000/FJSV,ulsa@3/IBMtape@1,0:st # |
Check the displayed device file to see if the IBM tape driver recognizes the LT220 drive.
../../devices/pci@1f,4000/FJSV,ulsa@3/IBMtape@1,0:st
1 2 3
1:"devices/pci@1f,4000/FJSV,ulsa@3" = This is the physical path name that indicates where the HBA is installed.
2:"IBMtape" = Indicates that the LT220 is controlled by the IBM tape driver
3:"1,0" = Hexadecimal display indicating "Target ID (LOOP ID),LUN" |
From these contents, the user can find out if the physical path is an HBA connected to the LT220, check whether or not the target ID (LOOP ID) and LUN information match the LT220 drive, and find out if the LT220 drive is controlled by the IBM tape driver.
