Only server tools available from the Presentation SAM server may be invoked from the M&R User Interface.
In a hierarchical SAM deployment, server tools that need to be executed at the Aggregate Sam (SAM-AGG) layer will fail if they rely on communication with an underlying Smarts domain manager. When the server tool executes a script, it will still work at the Aggregate SAM level (for example, the LSP Ping server tool in MPLS or the Remedy Adapter).
If your server tool is not working as expected, you may need to edit the ASL scripts to invoke the SAM-AGG layer to work around this problem.
