CMMVC8481E The storage pool cannot be deleted because at least one volume in the pool has received I/O within the defined volume protection period.
Explanation
If volume protection is enabled, and any volume in the storage pool being deleted received I/O within the defined volume protection time period, the storage pool deletion command fails. This is a policing behavior to protect I/O integrity.
This policing behavior is not overridden by the force flag.
User response
- Ensure that no volumes are in use in the pool. If you selected the wrong pool, repeat the command with the correct pool.
- To unmap all volumes in the pool, ensure that no host I/O is sent to any volume in the pool, wait the time that is specified in the vdisk_protection_time field in the lssystem command, then retry the storage pool deletion command.
- Alternatively, to disable volume protection warnings and behavior, disable the vdisk_protection-enabled field using the chsystem command, then retry the storage pool deletion command.
