Hi Zoltan,

Just for info (and to avoid buying possibly weak hardware), what type of
library are you speaking about ? Is it your IBM 3583-L72 ?
Cheers.

Thanks for the help.

I started the AUDIT and it has already flagged 2-tapes within the first
5-minutes.

I seem to have a bad drive, again.

This LTO2 library has been a royal pain since we got it. Already
replaced 1-PS, 1-DRIVE and internal board and now another drive.
Considering it only has 2-drives, that is a pretty bad reliability
record !

For us it turned out to be a drive problem, not firmware. Once I got all
the tapes cleaned off that were flagging the corrupted index, I then
monitored each time I got another corruption and it was always the same
drive.

Possibly......

However, my firmware is already at the level discussed, 4772 !

I am a bit of a newby when it comes to LTO2 tape technology, so please
excuse the possible "dumb" question.

I received the following error about my LTO2 tape:

11/17/2004 4:38:01 PM ANR8950W Device /dev/rmt3, volume 090046 has
issued the following Warning TapeAlert: The tape directory on the tape
cartridge just unloaded has been corrupted. File search performance will
be degraded. The tape directory can be rebuilt by reading all the data.

I was copying the contents to another tape since a previous error caused
this tape to go into UNAVAILABLE status.

This tape is now empty and scratched.

Is there something special I need to do to this tape or will it
automagically rebuild the "tape directory" when this tape gets reused ?
