CMMVC8478E: The mapping cannot be removed because the volume being unmapped has received I/O within the defined volume protection period.

Explanation

Volume protection is enabled, but the volume being unmapped has received I/O recently, within the defined volume protection time period, so the unmapping command fails. Receiving I/O generally indicates that a volume is in use.

User Response

  1. Ensure that this volume is intended to be unmapped. If you selected the wrong volume, repeat the unmapping command with the correct volume.
  2. To unmap this volume, ensure that no host I/O is sent to the volume, wait the time specified in the vdisk_protection_time field in the lssystem command since the last I/O was received, then retry the unmapping command.
  3. To disable volume protection and its warnings, disable the vdisk_protection-enabled field in the chsystem command.
