Lizette you are correct I found out from Tom this has been around since OS 360
must have missed that part of the class; at any rate we are starting to
allocate NON SMS DSNs that span multiple volsers. We kept getting SB37 abend
until we used the UNIT=(3390,P) and VOL=(,,,7) parameters.

The P indicates
Asks the system to allocate the same number of devices as requested in the
VOLUME volume-count or SER subparameter, whichever is higher. Thus, all volumes
for the data set are mounted in parallel.
If you specify the P subparameter for system-managed DASD, the system ignores
it. If you specify the P subparameter for system-managed tape libraries, the
system honors it
So according to the JCL Reference manual, the P will be ignored for DASD.
Since you say NON-SMS I am not sure.
However, you have only asked for 7 volumes. What size is the volumes it is
getting allocated on? 3390-3,3390-27????
Is there sufficient space on the 7 volumes?
Did you receive any messages when this ran? If so, please post the complete
messages?
The subparameter P has been around for a bit.
