Configuring CHAP for iSCSI Fault Domains

When Challenge Handshake Authentication Protocol (CHAP) authentication is enabled, the Storage Center challenges each iSCSI initiator in the fault domain for a shared secret (password). When CHAP is enabled it applies to all servers and remote Storage Centers that connect to the fault domain.

NOTE:When CHAP is enabled for an iSCSI fault domain, all iSCSI initiators in the fault domain (servers and Storage Centers) must be configured to use CHAP. All iSCSI initiators that are not configured to use CHAP are no longer able to communicate with the Storage Center iSCSI ports in the fault domain.
