SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

Resetting the SMF Master Process
The “RESET MON Command” (page 271) puts the SMF master process into the STOPPED state,
substate DOWN, reading for restarting.
1. Check the current status of the SMF master process:
-> STATUS $ZSMS
2. If it is not in the STOPPED state, substate DOWN:
-> RESET $ZSMS
3. Start the SMF master process:
-> START $ZSMS
4. Verify the SMF master process is started:
-> STATUS $ZSMS
Swapping Processors for the SMF Master Process
The “PRIMARY MON Command” (page 265) swaps the primary and backup processors for the
SMF master process. The current primary processor of a specified device becomes the backup
processor, and the backup processor becomes the primary processor, but the PRIMARYCPU and
BACKUPCPU values stay the same.
You typically swap processors when load balancing the system or preparing for disk replacement.
Examples
• To execute the primary process of $ZSMS in processor 3 (assuming it is configured to run in
processor 3):
-> PRIMARY $ZSMS, 3
• To make the current backup process of $ZSMS the primary process:
-> PRIMARY $ZSMS
