Re: Help on Medium Changer Required !

The changer device is a SCSI device, like the tape drives themselves. I'm not familiar with the API you're using, but I've done this manually. You can find documentation on the SCSI messages you can send the media changer from the manufacturer (usually on their website). You need to construct the SCSI messages and send them to the unit to manipulate it.

Look for docs on a "pass-thru scsi interface" in your OS' documentation on how to send SCSI messages to devices manually.

It's not as hard as it sounds.

Good luck!
No matter where you go, there you are.
