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

The storage pool finishes any current activity before it enters the STOPPED state. Virtual disks that
use the stopped pool encounter an error.
Resetting a Storage Pool
The “RESET POOL Command” (page 272)puts a storage pool into the STOPPED state, substate
DOWN, reading for restarting.
1. Check the current status of the storage pool:
-> STATUS $POOL01
2. If it is not in the STOPPED state, substate DOWN:
-> RESET $POOL01
3. Start the storage pool process:
-> START $POOL01
4. Verify the storage pool process is started:
-> STATUS $POOL01
Swapping Processors for a Pool Process
The “PRIMARY POOL Command” (page 265) swaps the primary and backup processors for a pool
process. The current primary processor 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 $POOL01 in processor 3 (assuming it is configured to run
in processor 3):
-> PRIMARY $POOL01, 3
• To make the current backup process of $POOL01 the primary process:
-> PRIMARY $POOL01
