Best I can guess is that the 9840C is not driving the required hardware
commands for processing this media, which from your commentary seems to
require 3590 emulation mode.
Do you have mixed use of native, 9840B, 3590 and 3490E for the 9840C and so
sometimes you swap to a compatible drive, but other times you just keep
swapping to non-compatible drives and eventually give up?
The 9840's are gen'ed as 3590's see below
UNIT TYPE STATUS
0440 3590 F-NRD
and we access them thru an esoteric UNIT=TSTK9840
to access regular 3490 tape or virtual 3490 tape we use the esoteric
UNIT=TAPEP and let SMS drive the allocation.
Real tape gen'ed as
UNIT TYPE STATUS
03A0 3490 O-NRD
Vitural tape
UNIT TYPE STATUS
1200 349L O-NRD
I?m presuming you?re using an ATL (E.g. 9310) and if so, is HSC driving
allocations to the correct drives, which for you would seem to be a 9840C
drive in 3590 emulation mode?
