I think I have the answer to this, but would like someone to verify since I don't speak "hardware driver-ese".
On this TSM Linux server, the 3590 drives it uses (FC via QLOGIC), are constantly "trashing" the tapes it writes to. Almost every tape is marked as "READONLY". Upon investigation, I found a correlation. In the activity log, I see a message about "end of file" being reached on the tape, followed by an error OP=FLUSH, Error Number=5, CC=0, KEY=40, ASC=00, ASCQ=00. The IBMtape driver is at 1.4.11. The only fixes since then (latest is 1.4.14) that might be close (this is where the "hardware driver-ese" comes in) is: "Fixed Write Filemark 0 handling at the early warning zone" ? Your thoughts/suggestions on this ?
