I've had some problemas with a Magstar 3570 last year. The problem was that
writes to tape would fail with undetermide errors:
07/14/1998 08:59:39 ANR8302E I/O error on drive RMT3 (/dev/rmt3) (OP=READ,
CC=0, KEY=03, ASC=11, ASCQ=01, Description=An undetermined error has
occurred). Refer to Appendix B in the 'Messages' manual for recommended
action.
The CE tried everything, from microdode refresh to parts replacement (nearly
all parts were replaced). In the end we talked IBM into replacing the 3570
library itself by a new unit, and since then the problem has stoped.
