As your sysout messages state, you cannot allocate a dataset with a primary
allocation that exceeds 65535 tracks (or, in this case, 4369 cylinders). I'm
not exactly sure how you get this dataset allocated in your SMS environment.
However, if you can bypass SMS control (or allocate to non-SMS

Hi Barry,
Is this thee Dr. Merrill that wrote those SMF/Operating systems difference
book I bought in the 80's or is this his Grandson speaking.
I forgot what it was called, but it was a piece of work at the time.
Amazing , that you are still around.

Subject: Problem Allocating DSN - 5000 CYl
Good Morning Gentle Readers,
I am having a tough time trying to allocate a sequential dsn of 5,000 cyls.
There are 3 mod-3 volumes empty. I checked the storage group and all is well.
If I allocate the dsn of 3,000 cyls it works. Do I need
Frank,
We are at RELEASE z/OS 01.09.00. You suggest that I use DSNTYPE=LARGE. I
assume you mean to create a DATACLAS LARGE?

DSNTYPE=LARGE is the JCL parameter to support extended PS files.

We're not using DSNTYPE=LARGE yet but IIRC, it allows you to allocate a
dataset larger than 65535 tracks on a single volume.
I thought it was stated earlier that the requestor was trying to allocate
a 5000 cylinder dataset and had 3 mod-3 devices - if I've remembered that

Since your are attempting to allocate a multi-volume SAS dataset, please
check the SAS - documentation. In there, you'll find JCL samples and a
description on how to do it.
I missed the part about this being a SAS dataset!?! If this is true,
nothing I said earlier will work. Our multi-volume

outside of SMS due to their special requirements.
If that's so, then you are stuck with thhe 65535 track limit.

Limit for nonvsam, non-extended datasets is 65535 tracks per volume up to
59 volumes.

Okay.
I thought there was a control block limitation.
I've never played with non-vsam files that large.
I stand (er, sit) corrected.

FYI - starting with SAS Version 8, there are no special requirements in an
SMS environment, as was the case with SAS V6 involving pre-allocating
multi-volume datasets.
I support several very large MICS and MXG SAS environments, all of which
play quite nicely with DFSMS. Also, if you still have
Short answer:
Yes, it needs to be Extended Format... which has a pre-req of SMS-Managed.
As Ted mentioned in one of the replies, a non-EF dataset does indeed have a
limit of 65k tracks.
