Configuring L9 Tape Library with MTX under Solaris (10)

Connect the library to your sun machine, if you have a HVDS library make sure you have a HVDS card! Make sure your L9 is not in continuous mode. This is a menu option, and makes the library look like a very large tape rather than a library.

Configuring SCSI Generic

If the file doesn't exist, create it, if it does, ensure that: /kernel/drv/sgen.conf contains: device-type-config-list="changer","sequential" inquiry-config-list= "*", "*"; name="sgen" class="scsi" target=5 lun=0; name="sgen" class="scsi" target=6 lun=0; This will ensure sgen scans your scsi bus and creates the required device files. If you have different SCSI ID's for you library changer and drive then alter the above. Next: touch /reconfigure reboot Another way to get the same result (ta Phil) is to (I've not tried it): add_drv -m '* 0660 root sys' -v sgen or after tweaking sgen.conf: update_drv sgen After the re-boot/change you should have something like: moonstone# ls -la /dev/scsi total 20 drwxr-xr-x 4 root root 512 Jan 7 11:22 . drwxr-xr-x 19 root sys 7168 Mar 23 14:26 .. drwxr-xr-x 2 root root 512 Jan 7 11:22 changer drwxr-xr-x 2 root root 512 Jan 7 10:54 sequential You may see more devices of course, changer and sequential are the ones you are after though.


Aquire and install mtx. When you have it installed, you should be able to test it with the following commands: mtx -f /dev/scsi/changer/c4t5d0 status You may need to change the c4t5d0 if you have not got a default setup. You should see something like: Storage Changer /dev/scsi/changer/c4t5d0:1 Drives, 9 Slots ( 0 Import/Export ) Data Transfer Element 0:Full (Storage Element 2 Loaded):VolumeTag = Storage Element 1:Full :VolumeTag= Storage Element 2:Empty:VolumeTag= Storage Element 3:Full :VolumeTag= Storage Element 4:Full :VolumeTag= Storage Element 5:Full :VolumeTag= Storage Element 6:Full :VolumeTag= Storage Element 7:Full :VolumeTag= Storage Element 8:Full :VolumeTag= Storage Element 9:Empty:VolumeTag= If you have put barcodes on your tapes, they will show up as the VolumeTag. If all is well, read the MTX manual, although here is a free clue: mtx -f /dev/scsi/changer/c4t5d0 status mtx -f /dev/scsi/changer/c4t5d0 load 1 mtx -f /dev/scsi/changer/c4t5d0 unload mtx -f /dev/scsi/changer/c4t5d0 load 2 mtx -f /dev/scsi/changer/c4t5d0 unload


The L9 uses Code 3of9 Barcodes, in the form AZ1234 - two letters and four numbers, anything else will not get detected. I am not sure quite who to give credit for this code too, but I got it from here -
