text: **Note:**The volume RHEL_VOLUME is mapped to both of the hosts by using the same SCSI 
  ID. Typically, that is the requirement for most host-based clustering software, such as 
  Microsoft Clustering Service (MSCS), IBM PowerHA, and VMware ESX clustering. 
  
  2. The volume RHEL_VOLUME is mapped to two hosts (RHEL_HOST and iSCSI_RHEL_HOST), and 
  can be seen by issuing the**lsvdiskhostmap**command, as shown in Example 8-24.
