text: (cid:2) iSCSI Aliases (Optional) 
  
  An*iSCSI alias*is a user-defined name that identifies the node to the host. Complete the 
  following steps to change an iSCSI alias: 
  
  a. Click an iSCSI alias. 
  b. Specify a name for it. 
  
  Each node has a unique iSCSI name that is associated with two IP addresses. After the 
  host starts the iSCSI connection to a target node, this IQN from the target node is visible in 
  the iSCSI configuration tool on the host. 
  
  (cid:2) iSNS and CHAP 
  
  You can specify the IP address for the iSCSI Storage Name Service (iSNS). Host systems 
  use the iSNS server to manage iSCSI targets and for iSCSI discovery. 
  
  You can also enable Challenge Handshake Authentication Protocol (CHAP) to 
  authenticate the system and iSCSI-attached hosts with the specified shared secret. 
  
  The CHAP secret is the authentication method that is used to restrict access for other 
  iSCSI hosts that use the same connection. You can set the CHAP for the whole system 
  under the system properties or for each host definition. The CHAP must be identical on 
  the server and the system/host definition. You can create an iSCSI host definition without 
  the use of a CHAP.
