Security
The mpx100/100b supports Challenge Handshake Authentication Protocol (CHAP) at the connection
setup. CHAP is a security protocol that includes support for both the bidirectional (mutual) authentication
and the one-way (target) authentication options. You can configure and set up CHAP in the
mpx100/100b. The target mpx100/100b can have its own unique password for One-Way CHAP
option. The initiator itself can have its unique password for the bidirectional CHAP option with the
mpx100/100b target. See “
” on page 203 for more information.
Configuring HP StorageWorks Continuous Access EVA and
Business Copy
Currently supported EVA software applications for Fibre Channel hosts such as HP StorageWorks
Continuous Access, Business Copy (BC), Storage System Scripting Utility (SSSU), and Replication
Solutions Manager (RSM) are supported with the EVA iSCSI connectivity option. The limitations of using
some of these applications on iSCSI hosts are discussed in
