text: **8.5.2 Advanced host administration by using the CLI**
  
  This section describes the following advanced host operations, which can be carried out by 
  using the CLI: 
  
  (cid:2) Mapping a volume to a host 
  (cid:2) Mapping a volume already mapped to a different host 
  (cid:2) Unmapping a volume from a host 
  (cid:2) Renaming a host 
  (cid:2) Host properties 
  
  **Mapping a volume to a host**
  To map a volume, complete the following steps: 
  
  1. To map a volume to a host, use the**mkvdiskhostmap**command, as shown in 
  Example 8-21. 
  
  Example 8-21 Mapping a volume 
  
  IBM_Storwize:ITSO-V7000:superuser>mkvdiskhostmap -host RHEL_HOST -scsi 0 
  RHEL_VOLUME 
  Virtual Disk to Host map, id [0], successfully created 
  
  2. The volume mapping can then be checked by issuing the**lshostvdiskmap**command 
  against that host, as shown in Example 8-22. 
  
  Example 8-22 Checking the mapped volume
