Tapeutil and IBM ..
I have a question to ask. Currently I'm having a problem to write to tape using TSM. I run tapeutil test as below on AIX 5.3 and IBM TS3100 Tape Library:
# tapeutil -f /dev/rmtX rwtest -b 1024 -c 10 -r 2 (ok)
# tapeutil -f /dev/rmtX rwtest -b 153600 -c 10 -r 2
(Operation failed with errno 5: I/O error)
IBM has collected the dump file for analysis and the report says that :
"There is no problem with the tape drive , the problem is with TSM "
Is that correct or IBM just bluff me.
