Challenge Handshake Authentication Protocol (CHAP) is an optional iSCSI authentication method where the storage array (target) authenticates iSCSI initiators on the host server. Two types of CHAP are supported • Target CHAP • Mutual CHAP Target CHAP In target CHAP, the storage array authenticates all requests for access issued by the iSCSI initiator(s) on the host server using a CHAP secret. To set up target CHAP authentication, you must enter a CHAP secret on the storage array, then configure each iSCSI initiator on the host server to send that secret each time it attempts to access the storage array. Mutual CHAP In addition to setting up target CHAP, you can set up mutual CHAP in which both the storage array and the iSCSI initiator authenticate each other. To set up mutual CHAP, configure the iSCSI initiator with a CHAP secret that the storage array must send to the host sever in order to establish a connection. In this two-way authentication process, both the host server and the storage array send information that the other must validate before a connection is allowed. Appendix-Manual Configuration 61
