Stopping a Storage Pool
Stopping a Storage Pool
The STOP POOL Command (page 14-150), like the ABORT POOL Command, makes
a storage pool inaccessible to user requests.
-> STOP $POOL5
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 14-128) 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 14-118) 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
