I'm working on a client's system that has a Dell 124 changer. Backup Exec only recognizes the unit as a stand alone and not a robotic library. I've been working through KB# 255501 (http://support.veritas.com/docs/255501) I believe the problem is that the SCSIChanger in not starting. Everything else looks ok. I've uninstalled/reinstalled the "Enable Robotic Library support" option, but the SCSIChanger will not start.
I'm pretty close to uninstalling Backup Exec from the system and reinstalling it. I'd like to know if there is anything else I can try.
Thanks

Problem solved without purchasing another SCSI card.
I upgraded to Backup Exec 11D.
I am really big on hacking through the registry when all else fails to see if I can find any issues or maybe something that points me in the right direction. I don't really want to change anything in a registry in a production environment, so I am also really big on testing in a test environment before installing anything in a production environment. If you don't know what you are doing in a registry, then skip that part.
In the registry (regedit), I specifically looked for the "SCSIChanger" key(s). Under HKLM\System\CurrentControlSet\Control\SCSIChanger, there is s key called "VSDLoadTable". If you open this key, it lists all the Robotic Libraries that your current version of Veritas detects. My HP 1/8 G2 autoloader was not listed.
Knowing that the SCSIChanger and scsichng.sys files are only installed on the server when the "Enable robotic Library" is selected when Veritas is installed, I realized that my version of Backup Exec 10 (including 10.1, 10.5, and 10D, and earlier versions of BE) do not support my autoloader. So I tried a series of upgrades to 10.1 or 10D and 10.5. Nothing worked until I upgraded to 11D.
Finally, 11D started the SCSIChanger and recognizes the autoloader as a robotic library in the Backup Exec software.
So the two most important parts of trying to get the autoloader to be a robotic library and NOT a stand-alone are to have the Adaptec SCSI controller set to Multi LUNs in the SCSI controller BIOS for the SCSI ID that detects the tape drive (SCSI ID 4 in my case), and to have Backup Exec 11D installed.
I hope that this helps you.
