Logon

If you plan to maintain data with TSM, then specify the TSM client node name. (The value that you specify must be a valid client node name in TSM.) A client node name in TSM can be from one to 128 bytes in length. When you define a cache-only primary storage node, the Logon field is ignored.

Note: The Logon field is not used on IBM® i and z/OS servers.
