I have Backup Exec 10.1 running on a Windows 2000 server. I have an external HP/Compaq 35/70 DLT drive. This drive and server have worked together for three years. Recently we noticed some performance issues with Verification failures. I ran the same jobs to disk and there were no errors, so I suspected cable or drive. I loaded HP Library and Tape Tools and upgraded the firmware on the drive. I replaced the SCSI cable at the same time.
Now it doesn't work at all. Windows recognizes the drive, and I can install drivers with Backup Exec, but when I try to access the drive in BE (to Inventory the tape, or erase it, or run a backup job) it says "No idle devices available." When I load Library & Tape Tools, it sees the drive but won't let me do anything with it. I can select the drive but get no options to change the firmware, test it, or anything.
I have reset every part of the configuration to be like it was before I made the changes. The only difference is the upgraded firmware, which I can't remove because Library & Tape Tools doesn't work now. I'm on day four of no backups and these are critical apps.
BTW. . .
The SCSI cable (25pin male to 68 pin male) from the server doesn't quite reach the drive, so there is an extension (which was in place originally). The drive has a 68 pin male to 68 pin male cable. It and the server 25/68 cable are connected by a gender changer. Is that as clear as mud?
