I have a Dell T-610 server that backs up to a TL-2000 tape library, it has a single LTO5 drive in it. Setup has been working almost flawlessly for years. Backups have recently begun failing, troubleshooting at the server shows a timeout and reset of the HBA card that communicates with the TL-2000. So it could be an issue with the card, or the library has a problem and isn't responding. I have the ITDT-DCR tool, the standard test fails the performance step on most runs. Again, since that's run from the server I'm not sure I can rule out the card, especially since performance is the only step that does not pass. I have the OpenManage-like web console to the TL-2000 open, it seems to pass all of the minimal testing that I can throw at it from there (this testing does not pass through the card). I've dumped the Bin files and other logs from the drive, but I can't make any sense of them. Can anyone point me in the right direction as to how I go about determining which part might need replacing?
