Explanation
If volume protection is enabled and an attempt
to delete the last volume copy occurs within the defined volume protection
time period after the volume received I/O, the volume removal command
fails. This policing behavior protects I/O integrity.
This policing
behavior:
- Is not affected by the volume being mapped or unmapped
- Does not occur when deleting one of two volume copies
- Is not overridden by using the force flag
User Response
- Ensure that you intend to unmap the volume. If you selected the
wrong volume, repeat the command with the correct volume.
- To unmap the volume, ensure that no host I/O is sent to the volume,
wait the time that is specified in the vdisk_protection_time field
in the lssystem command, then retry the volume
removal command.
- Alternatively, to disable volume protection warnings and behavior,
disable the vdisk_protection-enabled field using the chsystem command,
then retry the volume removal command.
