Using iSCSI
Changing the iSCSI Target Authentication
If an initiator requires mutual (bi-directional) authentication see "Entering
Mutual Authentication Permissions" on page 32.
1 Click the iSCSI tab, and then click Change Target Authentication.
2 Select None if no authentication is required for any initiator to access the
target.
NOTE:
If you select None, any initiator can access this target. Use this option
only if you do not require secure data. However, if you select both None and
CHAP at the same time, the storage array will allow an iSCSI initiator to log on
with or without CHAP authentication.
3 Select CHAP if you want any initiator that tries to access the target to
provide the target permissions. If CHAP is selected, but no CHAP secret is
defined, an error message appears.
Click CHAP Secret to see the Enter CHAP Secret dialog (see "Creating
CHAP Secrets" on page 32). You can define the permissions in this dialog.
Entering Mutual Authentication Permissions
Mutual authentication or two-way authentication is a way for a client or a
user to verify themselves to a host server, and for the host server to validate
itself to the user. This validation is accomplished in such a way that both
parties are sure of the other’s identity.
1 Click the iSCSI tab, and then click Enter Mutual Authentication
Permissions.
2 Select an initiator from the list. The initiator details are shown.
3 Select CHAP Secret to enter the initiator CHAP permissions in the dialog
that appears.
NOTE:
To add, modify, or delete an initiator, click the Modify tab, and then
click Edit Host Topology.
Creating CHAP Secrets
When you set up an authentication method, you can choose to create a
Challenge Handshake Authentication Protocol (CHAP) secret. The CHAP
secret is a password that is recognized by the initiator and the target. If you
are using mutual authentication to configure the MD3000i storage array, you
