Creating Additional File Systems and Directories

After allocating an HFS data set for the root file system and logging on as a TSO/E user, you can define additional directories in the root file system using the MKDIR command. For example, to create the /u/joe directory, issue:

   MKDIR ‘/u’
   MKDIR ‘/u/joe’

These directories can be used as mount points for additional mountable file systems. You can use an IBM-supplied program that creates directories, pseudo-TTY pairs, and device files. Interactive users and application programs can then add files to those additional file systems.

The MKDIR command requires written permission on the parent directory of the directory to be created.
