I have BackUp Exec 9.1 BLD 4691.1 installed on a Win2000 Advanced Server. I have a DELL PowerVault 128T autoloader. I'm using the latest BackUp Exec drivers. I've updated the drivers and firmware (1.62D) on the unit. I've loaded the unit with the approved LTO tapes. Backup Exec recognizes the autoloader and it's tape drive. It does an initilization and scan just fine. It lists all the tapes (after scan) in the Devices tab. The tapes all have bar codes which it reads correctly. The problem is with the inventory job. When I try to run it in order to get the tapes recognized, it sits in the job monitor and the status stays at "ready". I've run it with the BEMCMD command line utility and it returns -1 which indicates the inventory job failed. I've confirmed that the drive is cabled correctly; the tapes do not show up as cleaning tapes. I would appreciate your help in directing me to the correct course of action. I need to get this back up tape drive up and running ASAP. Since it won't inventory the tapes, it won't run a back up because it doesn't think there is media in the drives. Please help ASAP.
