Hello,
=20
I don't think that Media_unmount_delay was the guilty (but maybe I'm =
wrong)
Media_unmount_delay (normally according to Sag) apply, only, to user =
backup
(or restore) and if NetBackup =AB ask =BB a rewind to a drive and if =
the drive
is not ready ... well be patient and wait a while.
=20
I don't think that change a robot camera or it's controller would help =
you
on read/write error on drives.
=20
Ric have you only HP server ? If so do you have a tool to =
report/monitor
error/stat on Hp server (I don't remember it's name), if yes could you =
stop
this only on tape drives ??
=20
I've a customer with same strange behaviour and we found that this tool
monitor all the system, and regulary check drives with some mt =
commands.
When we stop this monitoring, we've never encounter problems.

I had simillar issue on L80. STK tech suggested that issue is may be =
related
to the Netbackup setting of "Media unmount delay" which is way too =
short by
default 3 minutes. What is happening tape is getting unmounted before =
it
completely rewound. I had some arguments with my co-workers about =
it....
Speed of LTO's vs DLT's, since the issues that never came up when we =
used
DLTs, but I was able to confirm the issues with my L80 logs some are =
exactly
what the tech suggested and some are similar. In addition the issues =
does
not seem to show up right away until LTO tapes have significant amount =
of
data - takes longer to rewind???... . I say if everything failes try to
change Media unmount delay to something like 15 minutes or so and see =
if it
makes any difference

Have the cables connecting the devices been replaced?=20
=20
I have similar problem recently with LTO drives and tried many things. =
My
environment was Solaris and there were some patches to apply ( although =
that
doesn't help sorry ), but the cables were mentioned plus I found LTO =
media
has a chip inside it which can be dislodged. If you shake the tapes and =
they
rattle loudly then most likely they are damaged. This could be more =
than one
tape if they have come from the same batch perhaps.
=20
Just some ideas

Our system:
=20
NB 4.5 MP5
master - HP-UX 11.00
media - 4 HP-UX 11.00, 1 HP-UX 11.11
STK L700 (HP20/700) w/10 HP LTO 1 drives w/SSO
5 HP 2/1 FC/SCSI bridges
1 Brocade 2800
=20
We're seeing tons of media-related errors (70% status 86 - media =
position,
30% status 84 - media write) spread across
all drives. Some nights we see no errors, other nights we'll see =
50-100
media-related failures. We see the failures when
reusing tapes and with brand new tapes. All drives have been cleaned
recently. We have had cases open w/Veritas and
HP for just over 4 weeks now. Veritas has examined over a months worth =
of
log files and has determined that the
problem is hardware related. HP replaced 3 drives, we saw media =
failures on
these 3 new drives the same day they were
replaced. HP also replaced the robot controller, the camera, and one =
of the
Fibre bridges. We're not seeing any
communication errors on the FC switch. Everything has the latest =
available
firmware. Whenever we get the status 84/86,
we see a lot of things like "cannot read from media socket 10", "ioctl
(MTREW) failed on media id 402280, drive index 4,
I/O error (bptm.c.7197)" and "write error on media id 402280, drive =
index 4,
writing header block, I/O error". Normally,
between 2 and 5 drives are downed every night - always with a tape =
stuck in
the the drive. Occasionally the system will
freeze dozens of tapes because they're seen as "unmountable" which =
leads to
a boatload of status 96 (no media)
failures. Our backup success rate has dropped from over 98% to below =
80% -
management is freaking out. We're
grasping at straws here folks, any help would be GREATLY appreciated!
