If that's what you want to do. It is what I would do baring further information about your situation since you're going from 300 to 3000 cylinders...
The Distributed File Service zFS Administration (SC23-6887-30), Chapter 4. Creating and managing zFS file systems using compatibility mode aggregates outlines two options with example JCL. Copying each file and directory of the aggregate to a larger data set--z/OS UNIX pax command. Copying the physical blocks of the aggregate to a larger data set--IDCAMS REPRO. Have used both methods many times.

Actually, probably easier, how about an entirely new filesystem /u/xyz ?

Please forgive the newbie question. I'm a coder, not a sysprog. I have an existing OMVS filesystem: ZFS 45 ACTIVE RDWR 10/06/2019 L=57 NAME=USERID.ZFS 16.15.27 Q=0 PATH=/u/userid OWNER=S0W1 AUTOMOVE=Y CLIENT=N It occupies 4000-odd tracks. I have a free DASD volume with 3000 cylinders. I want to add those 3000 cylinders to the filesystem above. Can someone tell me the commands? I am lost.
