Hi Peter, I sincerely empathize, as I've been living the same martyrdom as you some months ago. We had a brand new 3584 library, equiped with scsi lto drives, attached to the server thru 2108 San data gateways and fiber channeling. After months of investigation, upgrades of all kinds, drive exchanges etc ... We finally found that the length of fiber cables was a little bit too long, therefore generating timeouts errors, and subsequent tape failures. Don't know if it could be your case, but worth throwing an eye on it, if not already done ! My 2 cents !

I doubt it, but one never knows, do one?\ I would be very curious to hear what type of reliability problems you have seen with LTO. I have posted here before, but we have been experiencing an incredibly high number of read errors with our 3584 LTO library. We regularly see errors when trying to restore data from tapes. We have been auditing volumes recently and have seen errors on a tape during one audit, and then audit again, with no errors. There is no discernable pattern to these errors (across multiple tapes and multiple drives). Due to the nature of the data we are backing up, the data does not change often (and therefore the tapes are generally written to once, and the data stays there), so over-used tapes should not be an issue. Anything that you could share with the list, or me directly, would be greatly appreciated. Thanks.
