Syntax


1  DSMMIGFS
1  Control
2 ? options

Parameters

Control
Send a control statement to a space management client daemon to change the behavior of the daemon.
options
Use the option settings that are provided for this command to change client option settings applied from space management client daemons.

The control command applies for the space management client daemons watch daemon (dsmwatchd) and recall daemon (dsmrecalld).

–Type=enabletrace|disabletrace
The argument Type is mandatory. Specify whether the space management client tracing function should be enabled or disabled for a specified space management client daemon.
–PROcess=WD|RMD|RDD
The parameter PROcess is mandatory. Specify the space management client daemon process you want to update with new space management client option settings.

Specify the option WD to update the space management watch daemon (dsmwatchd).

Specify the option RMD to update the space management master recall daemon (dsmrecalld with PPID=1).

Specify the option RDD to update the space management distributor recall daemon (dsmrecalld with PPID=PID from master recall daemon).

–Options=name:value[::name:value]
The parameter Options is mandatory if the parameter -Type is set to enabletrace.

Specify the option TRACEFILE in combination with option value trace file name. Specify the option TRACEFLAGS in combination with the option value trace flags.

The trace file name must specify a file name in a directory that can be accessed from the space management client daemon process.

The remote node is not properly configured on the server.

Ensure that the remote node is properly configured and connected to the server by using TLS. This validates the remote node configuration and ensures that the information related to the remote node is sent to the server.

The trace flags must be one space management client trace flag or a list of space management client trace flags separated with blanks and enclosed with double quotes.

Note: In the current implementation of the control statement only trace options can be controlled for the specified space management client daemons.

Examples

Commands are provided for the example tasks.

Task Command
Enable tracing for the space management client daemon watch daemon with the /tmp/dsmwatchd.trc trace file and the SM SMVERBOSE SERVICE trace options. dsmmigfs control -type=enabletrace -process=WD -options=tracefile:/tmp/dsmwatchd.trc::traceflags:"SM SMVERBOSE SERVICE"
Disable tracing for the space management client daemon recall master daemon. dsmmigfs control -type=disabletrace -process=RMD
