Tracing the recall daemon

Edit online

You can start traces for only the recall daemon (dsmrecalld).

Procedure

This procedure relates to a static trace setting. 
The setting is applied to all subsequent daemon starts.
  1. In an IBM® Storage Scale environment, issue the following command: dsmmigfs disableFailover.
  2. Add trace options to the dsm.opt client options file as described in Enabling a Space Management client trace.
  3. Stop and restart the recall daemon.
    1. Stop the recall daemon by using the following command: dmkilld.
    2. Start the recall daemon by using the following command: dmrecalld.
  4. Remove the trace options from the dsm.opt file.
    If you do not remove the trace options, other daemons are traced when you restart other daemons.
  5. In an IBM Storage Scale environment, issue the following command: dsmmigfs enableFailover. 
You can also execute a procedure for a dynamic trace setting. 
The setting is applied to the currently running daemon process.
  1. Use the command dsmmigfs control to enable dynamic tracing. See dsmmigfs control for details.

Results

The space management client captures data from the recall daemon.

What to do next

You can stop tracing the recall daemon in two steps:
  1. Verify that the dsm.opt client options file does not contain trace options.
  2. Stop and restart the recall daemon as described in step 3.
