They were all purchased summer 2003 as part of the whole order...x345
server..3853..40-tapes. So I would think they are IBM, but I'll try to find
out. I remember one tape in particular that would always go into ReadOnly I
finally had them remove it from the library.

Hi, what type of tape is it ? Imation, IBM... ?

When did you get them, 2003 or sooner ?

We have to replace all Imation tapes delivered between 2001 and 2002 !! At
about one third of the tape, we get the tape in r/o by TSM because of EOD
missing and write errors.

Subject: Corrupted LTO CM Index


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!
