TACL Macro for Configuring
MSGMON, SANMAN, and SNETMON
The example macro in this appendix automates the process of adding MSGMON,
SANMAN, and SNETMON to the system-configuration database. (The manual steps
for adding these processes are documented in Section 3, Installing and Configuring a
ServerNet Cluster).
The macro:
•
Detects the number of processors currently loaded and prompts you to confirm this
number (if your system has fewer than four processors)
•
Aborts and deletes the MSGMON, SANMAN, and SNETMON processes, if they
are already present
•
Returns error messages if the processes could not be successfully deleted
•
Adds the processes using a processor list that is appropriate for the system size
•
Starts MSGMON, SANMAN, and SNETMON and attempts to start the ServerNet
cluster subsystem
To use the macro:
1. Log on using the super ID (255, 255).
2. Copy the macro to (or create it in) the $SYSTEM.ZSUPPORT subvolume.
3. At a TACL prompt, type RUN ZPMCONF.
4. When the macro finishes, check the SCF state of $ZZSCL to make sure that it is in
the STARTED state:
-> SCF STATUS PROCESS $ZZKRN.#ZZSCL
5. If $ZZSCL is not started, start it:
-> SCF START PROCESS $ZZKRN.#ZZSCL
Note. Before using the macro, note the following:
•
The macro is intended as an example and might not be appropriate for all systems.
•
You must log on using the super ID (255, 255) in order to run the macro successfully.
•
Do not run the macro on a system that is currently a member of a ServerNet cluster.
MSGMON, SANMAN, and SNETMON will be aborted, and the connection to the cluster
will be lost temporarily.
