Mounting file systems
After installation is complete, you need to create file systems and mount them to your root file system or somewhere else in the hierarchy.
If /// is used as a placeholder in file system
names, mount processing will replace the /// with ZFS. If it is a HFS file system,
mount processing will fail because HFS is not a supported file system type as of V2R5.
Tip: To verify that file systems specified in BPXPRMxx are mounted, use the
USS_FILESYS_PARMLIB_MOUNTS check provided by IBM® Health
Checker for z/OS®.
