I ran into this problem big time a couple weeks ago and Dave Canan posted an excellent note about the corrupted index on LTO cartridges. Since then I've had a couple tapes become corrupted. After the incident, I checked out all my tapes and checked them in with CHECKLABEL=YES. This identified all the tapes with existing corrupted index chips with the TAPEALERT messages. I then MOVE DATA all these tapes and they were reused. Yesterday again I had a tape that was checked in with CHECKL=YES that did not indicate a problem, but this morning after being used as a copypool tape when it was dismounted it for the ANR8950W message about a corrupted index.
What is causing this corruption?? I have updated the drives and library to the latest firmware. There were no I/O errors or any other indications of a problem. Is this tape just bad?? Before we were having SCSI errors on the motherboard of the x345 server. We believe this caused the corruption, now I'm not so sure. Any help is greatly appreciated!
