I believe there are two separate components that can issue the CCW command
which causes the display on the 3490 tape drive.

Allocation:     5752SC1B4
Open/Close/EOV: 5695DF107

Here's what I would do:  Try to get specific examples of mounts where the
message is missing.  Were they associated with mount message IEF233A -
that's Alocation.  Were they associated with IEC501A - that's
Open/Close/EOV.

If you find that all examples the operators come up with are Allocation,
open a PMR with Allocation.  If Open/Close/EOV, then OCE.  If both, then
perhaps it might be a hardware problem.

Just a suggestion - hope it helps!
