End of Marker Unreadable, and many other errors - MSL4048

[Megan G]

Does anyone know if the problem with AutoRun and TUR requests can cause EOM unreadable? HP advised me to add the AutoRun key, and it's not solving any problems. The Symantec article confuses me a bit as it says it needs the TUR requests?

I am having this problem more and more frequently (pretty random, occurs more with one drive), and my drives keep requesting to be cleaned once a week or so. It's an HP library, MSL4048 with QTY 4 LTO2 drives. Every single drive is reporting errors, and they didn't all start at the same time. I think the heads on them are really worn and need to be replaced, or there are internal issues with the library. The system is about 3 years old, and each drive sees 6-10 hours of use per day on average.

Anyone have any experiece with issues such as this? I've updated firmware, swapped cables, used two different HBAs for my SCSI connections, new cleaning tape, different terminators, etc. etc. I've been in touch with HP to try to get this sorted, but if someone has some ideas as to how I could get to a speedier resolution it would be appreciated. Been doing all those test with L&TT and emailing them to HP :)
