Backup Exec tape drives continuously go Offline

Good day, We have an HP MSL 2048 Robotic Library with Backup Exec since 2004 and have never had any problems, until recently. Over the past couple of months our tape drives continuously set itself to Offline either at the end of the cycle, just before, or sometimes at random.  In most cases, this causes us to have to re-run a majority of the scheduled backups once we come back in as they would have failed over night.  Once they are offline, it is impossible to get them to come back online without powering down the library.  

Curious if anyone has had a similar issue and if so, what seemed to be the fix?

Thanks for any help you may provide.

Check your System event log around the time of the problem. Do you see errors from the SCSI controller driver or the tape drive driver. Especially event 7, 9, 11 or 15. They would indicate hardware problems. Tape drives going offline generally indicate hardware problems.

Check SCSI cables for problems (loose, bent pins, ...). Make sure to clean the tape drive with a known good cleaning tape.

You should also download and update the firmware for tape drive and robotic library.
Then do the following:
* Install the latest device drivers. http://seer.entsupport.symantec.com/docs/285593.htm
* Reboot if required.
* In Backup Exec, right-click the tape drive(s) and uncheck Enable. Right-click again and choose Delete.
* In Backup Exec, right-click the robotic library and uncheck Enable. Right-click again and choose Delete.
* Close the GUI
* Stop Backup Exec services.
* Run program files\veritas\backup exec\nt\tapeinst.exe. Choose to "Use VERITAS tape drivers for all devices". Also make sure to check "Delete entries for tape devices that are not available". run through the wizard.
* Start the services
* Start the GUI - try again.

If all the above does not permanently solve the problem, you should start replacing hardware (SCSI card, cables, robotic library and drive, terminator).
