text: Figure 6-63 Removing an MDisk from a pool 
  
  Confirming the action starts the migration of the volumes to extents from other MDisks that 
  remain in the pool. When the action is completed, the MDisk is removed from the storage pool 
  and returns to Unmanaged. 
  
  Ensure that you have enough available capacity remaining in the storage pool to allocate the 
  data being migrated from the removed MDisk. Otherwise, this command fails. 
  
  **Important:**The MDisk that you are removing must remain accessible to the system while 
  all data is copied to other MDisks in the same storage pool. If the MDisk is unmapped 
  before the migration finishes, all volumes in the storage pool go offline and remain in this 
  state until the removed MDisk is connected again.
