text: **7.8.15 Deleting a volume to host mapping**
  
  Deleting a volume mapping does not affect the volume. Instead, it removes only the host’s 
  ability to use the volume. Use the**rmvdiskhostmap**command to unmap a volume from a host, 
  as shown in Example 7-27. 
  
  Example 7-27 The rmvdiskhostmap command 
  
  IBM_2145:ITSO_CLUSTER:superuser>rmvdiskhostmap -host Tiger volume_D 
  
  This command unmaps the volume that is called volume_D from the host that is called Tiger. 
  
  You can also use the**rmvolumehostclustermap**command to delete a volume mapping from a 
  host cluster, as shown in Example 7-28. 
  
  Example 7-28 The rmvolumehostclustermap command 
  
  IBM_Storwize:ITSO:superuser>rmvolumehostclustermap -hostcluster vmware_cluster 
  UNCOMPRESSED_VOL 
  
  This command unmaps the volume called UNCOMPRESSED_VOL from the host cluster called 
  vmware_cluster. 
  
  **Note:**Removing a volume mapped to the host makes the volume unavailable for I/O 
  operations. Ensure that the host is prepared for this before removing a volume mapping.
