Passing a MODIFY command string to a physical file system (PFS) through a logical file system (LFS)
The MODIFY OMVS command passes a modify command to a PFS through an LFS interface. This command is useful when a PFS runs in the OMVS address space and wants to support MODIFY commands. It can also be used for PFSes that run in their own address space.
- Indicates the name of the PFS that will receive the command_string. It is the name used on the FILESYSTYPE TYPE statement from the BPXPRMxx parmlib member that defined the PFS.
- The command string to be passed from the LFS to the PFS. The LFS passes the command string to
the PFS with a vfs_pfsctl with command code PC_MODIFYPFS. For a description of MODIFY commands that
are supported by zFS, see z/OS File System Administration.
For a description of the MODIFY commands that are supported by TFS, see z/OS UNIX System Services Planning.
