Hi Managers
we have been facing some problems in tape backup. we
use Veritas netbackup with a DLT/Robot arm model ADIC
SCALAR on DU 4.0d pk3.(I wonder in uerf log there is a
entry for quantum DLT)
the symptom is backup software or OS times out after
trying to connect to tape device..this is
intermittent..we have a another AIT is also daisy
chained with a Narrow SCSI controller.when i do a uerf
, I find the messages disturbing but not exactly
understand the meanings..I think, if i interpret the
uerf messages correctly, I am halfway through..
So I am attaching the actual file related with some
irrelevant details filtered .i need some sort of
explanantion or guidance what it is..
and is it related to device or controller etc..
I don't know whether I have correctly extracted info.
(i mean related to tape)from uerf log..
TIA
...........uerf log follows for Aug2 1999.
