Configuring Remote Connections Using CHAP

Challenge Handshake Authentication Protocol (CHAP) is an iSCSI security option that

provides connection authentication based on secrets (essentially passwords) that are

exchanged when a connection is established.

Configuring Remote Storage Center Connections using CHAP consists of the following

steps:

1 Enabling CHAP in each system.

2 Add Remote Compellent Connection from System 1 to System 2.

3 Add Remote Compellent Initiator from System 2 to System 1

4 Add Remote Compellent Connections from System 2 to System 1.

5 Add Remote Compellent Initiator from System 1 to System 2.

Note Once CHAP is enabled (Step 1), Steps 2 through 5 can be done in any order.

Remember the following:

• If Virtual Ports are enabled, CHAP is enabled in the Properties window of the Control

Port.

• In a legacy system (one in which Virtual Ports are not enabled), CHAP is enabled in the

Properties window of each iSCSI IO port.

• The difference between adding a Remote CHAP Initiator and a Remote Storage Center

CHAP Initiator is simply that Storage Center enters the first part of the Compellent IQN

name in the Remote Compellent Initiator window.

• If you add an iSCSI Remote Connection or Remote Compellent CHAP Initiator from an

iSCSI folder, the connection or initiator is added for all ports. You can select an individual

card (in legacy mode) or Control Port (in Virtual Port mode) and add a remote iSCSI

connection or initiator only to that port.

Displaying Remote CHAP Initiators

Before configuring new CHAP initiators, you can view existing remote CHAP initiators.

• In a legacy system (one in which Virtual Ports are not enabled), Remote CHAP Initiators

are on the iSCSI IO card.

• In a system with Virtual Ports, select the Control Port.

From the shortcut menu, select Properties. The Properties window displaying the Remote

CHAP Initiator tab appears. This tab displays information about existing CHAP initiators.
