Henrry,
did you changed the settings for the FC HBA? Can you provide the output of
AIX command "lsattr -El fcs0" (or fcsN if you have more HBAs)? Also level
of library firmware and drives microcode might sched some light.
Tape operations (and especially LTO ones) require larger blocks of data to
be send to keep streaming.

Subject: LTO 3583 Drive errors with TSM 5.1.5.2 on AIX 5.1
Hi,
I have the following environment:
TSM Server 5.1.5.2 on AIX 5.1, a FC Adapter 6228 and an IBM LTO 3583 with
SANDataGateway.
When the library is performing an intensive write process, I get the
following messages in the activity log:
01/07/03 17:02:48 ANR8311E An I/O error occurred while accessing drive
3583DRV2 (/dev/rmt2) for WRITE operation, errno = 5.
01/07/03 17:02:48 ANR1411W Access mode for volume 393ACA now set to
"read-only" due to write error.
01/07/03 17:02:48 ANR8302E I/O error on drive 3583DRV2 (/dev/rmt2)
(OP=OFFL, Error Number=5, CC=0, KEY=0B, ASC=4E, ASCQ=00,
SENSE=70.00.0B.00.00.00.00.1C.00.00.00.00.4E.00.00.00.10-.47.00.00.00.01.20.20.20.20.20.20.20.1A.00.01.40.DF.01.0-0,
Description=An undetermined error has occurred). Refer to Appendix D in
the
'Messages' manual for recommended action.
IBM changed this drive twice, but I still get the same messages.
Does somebody know if it is a known problem with the OS or the TSM
version?
Thanks in advance,
Henry Aranda
