Unable to backup to LTO-5 tape library

[twflynch]

I have an LTO 5 tape set that I have been using to backup my xSAN volume to. Recently I have been unable to backup my files, the script appears to hang at the end of the "scan" phase. The volume that I am backing up is about 5 TB and contains over 5 million files.

 

Here is a log from a recent attempt that made it past the scan phase but all subsequent attempts have hung at the end of the scan phase:

Completed: 0 files, 0 B

Performance: 0 MB/minute

Duration: 20:18:12 (20:17:34 idle/loading/preparing)

I've seen these in the log from the "View" menu:

stucFinished: [QUANTUM|Scalar i40-i80|123G] incorrect scsiServiceResponse 0x70682630, scsiStatus 0x70682630

stucFinished: [1|1|1] transaction result 0x70694b90

Any ideas on what this error means and why I can no longer write to my tape library? The library is attached via fibre channel to a qlogic fibre switch.

This is critical that I get this working again as I am having disk problems with my storage array and need a good backup.

 

Thanks

Check the fibre channel cables.

Check the fibre channel card firmware and drivers.
