text: **7.8.8 Deleting a volume**
  
  Use the**rmvdisk**command to delete a volume. When this command is run on a managed 
  mode volume, any data on the volume is lost, and the extents that made up this volume are 
  returned to the pool of free extents in the storage pool. 
  
  If any remote copy, IBM FlashCopy, or host mappings still exist for the target of**rmvdisk**
  command, the delete fails unless the**-force**flag is specified. This flag causes the deletion of 
  the volume and any volume to host mappings and copy mappings. 
  
  If the volume is being migrated to image mode, the delete fails unless the**-force**flag is 
  specified. Use of**-force**flag halts the migration and then deletes the volume. 
  
  If the command succeeds (without the**-force**flag) for an image mode volume, the write 
  cache data is flushed to the storage before the volume is removed. Therefore, the underlying 
  LU is consistent with the disk state from the point of view of the host using the image-mode 
  volume (crash-consistent file system). If the**-force**flag is used, consistency is not ensured; 
  that is, data the host believes to be written might not be present on the LU.
