StorEdge L9 Autoloader on Solaris 8

Question

Hi,
I recently found a StorEdge L9 Autoloader with Quantum DLT8000 unused in my organisation and trying to get it work.
The Autoloader looks to be working and I can run manual UFSDUMPS onto the tape. However, I have problems all over to get MTX working with the Autoloader working.
I installed MTX from sunfreeware.com and have edited the /kernel/drv/sgen.conf file to reflect as follows:
device-type-config-list="changer","sequential";
inquiry-config-list= "*", "*";
and have enabled all lines like
name="sgen" class="scsi" target=0 lun=0;
However, after a recofigure reboot I cannot find the /dev/scsi/changer/ being created. However, I can see /dev/scsi/sequential/ being created.
The probe-scsi-all from OBP shows as follows:
ok probe-scsi-all
/pci@1f,2000/scsi@1,1
Target 0
Unit 0 Disk Symbios StorEDGE A1000 0205
Unit 1 Device type 20 Symbios StorEDGE A1000 0205
Unit 2 Device type 20 Symbios StorEDGE A1000 0205

Unit 5 Device type 20 Symbios StorEDGE A1000 0205
Unit 6 Device type 20 Symbios StorEDGE A1000 0205
Unit 7 Device type 20 Symbios StorEDGE A1000 0205
/pci@1f,2000/scsi@1
Target 4
Unit 0 Removable Tape QUANTUM DLT8000 0114

Unit 0 Disk SEAGATE ST318404LSUN18G 4203
Target 6
Unit 0 Removable Read Only device TOSHIBA XM5701TASUN12XCD2395
As you can see, the Quantum DLT8000 shows up but nothing at all about the autoloader. I'm not sure if it would be listed there but I've googled a lot and can find people say it should be.
The SCSI IDs are "0" for Autoloader and "1" for Drive. The Autoloader and the A1000 are conncted to the same Differential SCSI card on the server. However, disconnecting the A1000 doesn't help as well.

Managed to get this problem fixed just when I was at the end of the rope.
I realised once when there was a problem with a external SCSI tape drive on a DELL 2850 (RHEL3), I have to shutdown the server and the Tape drive, disconnect all the cables to drain any static energies in there and reconnect the cables and start the server wich eventually fixed the problem.
As a last resort, I tried this by disconnecting all the SCSI cables and the switching off the devices, power-off the server and leave for a few minutes and restarted with the autochanger connected to the port where the A1000 was connected and bingo, probe-scsi-all was able to see the autoloader and then the tape drive. Shutdown again and connected the A1000 to the port where the L9 was connected earlier and all was fine.
Rebooted the server a few times and all was fine. Edited the /kernel/drv/sgen.conf file and rebooted the server and I can see the "/dev/scsi/changer" and MTX does respond.
Hope this helps someone who has a similar problem.
