Use a DATACLAS supporting EA. Ask your Storage Team.

Not possible from remote as we don't have the possibility to look at your available Storage Classes and ACS routines. For the use of the STORCLAS parameter, please see JCL reference.

If you want/have to allocate on a specific volume and the volume and dataset are SMS managed then it needs to be a Guaranteed_Space type STORCLAS, otherwise the volume parameter is ignored and SMS will just allocate the dataset wherever the ACS routines decide.
Whether a STORCLAS is accepted in your JCL or IDCAMS statements depends on how the ACS routines are written in your local site.
You have to code the VOLUMES(volser) parameter in your DEFINE statement, along with a DATACLAS that allows Extended Addressability VSAM, and your STORCLAS.

e.g.
DEFINE CL(NAME(YOUR.ESDS.DATA.SET)
NIXD -
RECORDSIZE(00102 000102) -
SHR(2 3) -
CISZ(18432) -
FSPC(000 000) -
DATACLAS(EXTVSAM) -
STORCLAS(GSPACEVS) -
RECORDS(370000 370000) -
VOLUMES(volume) -
))

STORCLASses can even be RACF protected. So from remote it's hard to give any working advices w/o knowing the environment.
