Setting Up and Configuring CHAP Authentication
Enabling Host CHAP is an option that can be set up at the ESX system administrator's discretion.
The following example outlines the procedures for host (initiator) CHAP which is available as of
ESX 3.x. As of ESX 4.0, mutual (bidirectional, initiator-target) CHAP is also available.
1. Issue the HP 3PAR OS CLI showhost command to verify that a host definition has been
created on HP 3PAR StoreServ Storage for the ESX host that will have CHAP enabled.
# showhost
Id Name ----------------WWN/iSCSI_Name---------------- Port
0 ESX1 iqn.1998-01.com.vmware:hpdl380-01-11a38a59 0:1:2
iqn.1998-01.com.vmware:hpdl380-01-11a38a59 1:1:2
The following example uses the CHAP secret (CHAP password) host_secret3 for the ESX
host. Be aware that the CHAP secret must be at least 12 characters long.
2. On the ESX host's VI/vSphere client, select the Configuration tab, then click Storage Adapters
under the Hardware pane. Select the iSCSI Software Adapter and select the Properties link.
For ESX 3.5, select the CHAP Authentication tab, and then select the Use the following CHAP
credentials radio button.

For ESX/ESXi 4.x or ESX/ESXi 5.x, select the Use initiator name check box.
