Looking at your data briefly, I have seen this happen a couple of times.
It was with an IBM 3575-L32 library with C-XL drives connected to
Rs6000 F50, AIX 4.3.3. and TSM 3.7.4.0. Tapes would sit at a spot for
long time (hour or so) but there would be no errors in actlog or AIX errpt -
no messages at all. Basically it was a drive problem - like it was running
in real slow motion.
IBM CE didn't beleive me and ran diagnostics with his tape, instead
of taking a couple of minutes or so for diag, it was running 10-15 minutes
and giving no error and not finishing. He replaced drive and o.k.
I know I had this at least twice.

. . . given the above, this system is sitting essentially idle; but in
the q pro output above the Files Backed Up has been sitting at the same
number with the same Current Physical File for more than 30-minutes.
Surely, this should have completed by now!?!
JFYI, given that I issued the command with maxpr=2 there should have
been two processes; one of the processes completed successfully.
There are no errors in the actlog. When I go through the 3494's web
interface, there are no commands in queue. All drives are available,
all paths are available, no errors on FC adapters, or network
interfaces. No errors on either volume. I know this should really not
be affected, but here it is anyway: (a) CPU Utilization for last
20-minutes on all processors is less than 1% (b) no page faults, page
ins or outs, and (c) all hard drives are at 0% busy.
Anyone else experienced something like this? Any suggestions?
TIA
