When we first had this problem, I had our IBM CE open a hardware
case with the 3494 folks. They said "it must be your network" and closed the
case. I had our network folks look around and an put some sniffers on the
lines, but they found nothing.
I have not logged a software call to ADSM support, although if I saw
this problem more often, I would be inclined to do so (have to allocate my
time to the things that keep me awake at night).
The error I am getting is always on this operation, which looks to be a
mount request:
ANR8824E I/O Error on library TAPELIB2; request some-number for
operation 004C6D31
Just to compare your environment to ours:
Hardware: various RS/6000 servers
AIX OS: 4.2.1 and 4.3.2 , both have logged this error.
ADSM ver: 3.2.1.40
Atape ver: 4.4.0.0
atldd ver: 4.0.1.0
3590e (FW): C747
We have one ADSM server that has not logged any of these errors, and
it's 7 drives are 3490B1A drives but everything else is the same. We will be
upgrading those drives to 3590E1As tomorrow and it will be interesting to
see if I begin to log this error on this server.
