text: **Note:**When the host is initially configured, the default authentication method is set to no 
  authentication, and no CHAP secret is set. To set a CHAP secret for authenticating the 
  iSCSI host with the Storwize V7000 system, use the**chhost**command with the**chapsecret**
  parameter. If you must display a CHAP secret for a defined server, use the**lsiscsiauth**
  command. The**lsiscsiauth**command lists the CHAP secret that is configured for 
  authenticating an entity to the Storwize V7000 system. 
  
  FC hosts and iSCSI hosts are handled in the same way operationally after they are 
  created. 
  
  **Creating NVMe hosts**
  Before you create an NVMe host, you need to know the NVMe qualified name (NQN) address 
  of the host. See your host operating system-specific documentation to find the NQN of the 
  host. 
  
  Create a host by completing the following steps: 
  
  1. Create the NVMe host by using the**mkhost**command, as shown in Example 8-19.
