There is an IBM course, SS84. It is, like most other storage-related IBM

I would suggest using extended addressability VSAM to avoid the 4GB limit

it is supported for the OCDS). I'd also recommend using RLS as I've seen it

Two wildly different thoughts:
1. Might it be possible to mount the offending tape manually depending of

2. DFSMShsm AUDIT MEDIACONTROLS once the tape has been transported to the

The DADSM PARTREL macro might do this although the documentation isn't
explicit. I have a vague recollection that what you ask is possible and
that this might be the underlying service needed.
It is used by DFSMSdss RELEASE so should be easily testable.

Claude, I have used DFSORT in the past to create reports, usually for
one-off projects.
A few thoughts on the idea of HSM reporting:
1. Detecting migrate/recall thrashing is a good thing to do
2. Reviewing migration and backup failures is probably worthwhile. I've
seen datasets failing to migrate
DFSMShsm has done recall tape takeaway for quite some time. If a recall
needs a tape that is being used as recycle input (or, IIRC, TAPECOPY), the
using task is forced to give the tape up.

of the sustained data rate is a little clumsy but, in brief, 8 gives two
stripes and 12 gives 3 stripes for 3390 device geometry.
Last time I looked, the throughput scaled roughly linearly with the number of
stripes.

I've just remembered that extended format also allows hardware compression
using zEDC cards so a compressed extended format sequential data set would also
be worth considering if the hardware's there.

If you were hoping to get hits for IBM publications, using the correct

the sequence of names was when it first became available to customers but
it became DFSMSrmm with the advent of DFSMS/MVS in 1992.
