Modifying a Local LU — LUADD Statement z/OS MVS Planning: APPC/MVS Management SA23-1388-00 |
|
You can modify an LU by overriding a previous LUADD statement with
another LUADD statement that names the existing LU and changes the
definition. The LU definitions you can modify are:
To change other parameter values that define an existing LU, you must delete the LU with an LUDEL statement and re-identify the LU with a new LUADD with different values for those parameters. The two statements, the LUDEL and the new LUADD, cannot be in the same parmlib member; and, if in two parmlib members, the two parmlib members cannot be specified in the same SET command. Modifying previous LUADD statements is useful when an installation needs to specify a different configuration for the same LU on a regular basis. For example, the installation might need one LU definition for a particular kind of work during first shift, and another definition for the same LU for another kind of work during second shift. The installation can keep each definition in a separate parmlib member. |
