I've got a Dell PowerEdge 2900 running MS SBS Server 2003 and Backup Exec 12 with a Dell branded Quantum internal DAT 72 drive connected to an Adaptec 39320A SCSI card. Everything was working great, except that the jobs were running out of tape. Our solution was to install another drive and setup a Cascaded Drive Pool in Backup Exec. We used an identical drive pulled from another Dell system, only changing the SCSI ID before install from the default of 6 to 5. The SCSI card has 2 internal connectors and each drive is on its own connector and cable. There are no other SCSI devices.
The problem is that the second, newly installed drive shows up as offline in Backup Exec. Device Manager says everything is working properly. I have tried uninstalling both drives from Device Manager and reinstalling and have tried both drivers from Symantec and Quantum, but there has been no change. Any ideas on on how to get this drive to work?
