Hi
Has anyone else encountered problems with LTO-2 support and
patch 108725-17? We've got a number of IBM LTO-2 drives and
they're now behaving like fixed block devices on our
Netbackup server. I think it might be due to LTO-2 support
having been (accidentally?) removed from 108725-17.
There's the following message in /var/log/messages
Sep 29 12:29:16 bamboo scsi: [ID 107833 kern.notice]
/pci@1f,4000/JNI,FCR@5/st@0,4 (st65):
Sep 29 12:29:16 bamboo Fixed record length (4096 byte
blocks) I/O
And when you try to read from the tape:
Sep 29 11:26:40 bamboo scsi: [ID 107833 kern.warning]
WARNING: /pci@1f,4000/JNI,FCR@5/st@0,4 (st65):

Incorrect Length Indicator Set
Looking at /kernel/drv/st it looks like the inquiry string
for IBM LTO-2 was removed:
(108725-17)
# strings st| grep ULTRIUM
SEAGATE ULTRIUM06242-XX
IBM ULTRIUM-TD1
On an older version (108725-16)
strings st | grep ULTRIUM
SEAGATE ULTRIUM06242-XX
IBM ULTRIUM-TD2
IBM ULTRIUM-TD1
I'm planning to downgrade ASAP to workaround it, but wondered
if anyone else has had this problem or if it's just us....
Cheers,
Andy
