TSM 6.3.5 on Windows, LTO6 drives in a TS4500. Customer had an LTO4 drive go bad and damaged a dozen tapes (maybe more!) before we figured out which one was doing it and mothballed that drive.
Now trying to MOVE DATA, restore vol, audit, restore stgpool and otherwise fix the damaged tapes using LTO6 drives. Trying to run AUDITs on these puppies takes 12 hours or more each, because the LTO drive just sits and whirs for a loooooooong time before deciding that it really, really can't read the bad spot and moves on to the next spot. This is "normal" LTO behavior that I've seen before; appropriate I/O errors and tapealert msgs are issued, etc. We know the cartridges do have bad spots, that's not the issue. What I'd like to know is if anybody has figured out a way to control or adjust the interval before the drive gives up and moves on, this is way overkill. Is that a settable parm in the driver perhaps? or the library?
