Configuring Secured iSCSI Connections Using CHAP
37
iSCSI Initiator Settings
1 Go to the Discovery tab.
2 Log in to the Target on which you have enabled CHAP by clicking iSCSI
Initiator Properties
→ Targets tab→ Log On.... (Please refer "iSCSI Target
Settings" on page 36).
3 In the Log On to Target window, select Advanced.
4 In the Advanced Settings window, select the check box for
CHAP logon information.
The User name fields displays the IQN of the Initiator automatically.
5 In the Target secret field enter the same value of the target secret that you
set in the iSCSI Target and click OK.
If the Target secret value is correct, you are logged on to the Target.
Otherwise the logon fails along with authentication failure.
Mutual CHAP Authentication
When you use mutual CHAP authentication, the Target and the Initiator
authenticate each other. A separate secret is set for each Target and for each
Initiator in the storage area network (SAN).
Initiator Settings
1 On the iSCSI Initiator, go to the iSCSI Initiator Properties→ General tab→
Secret button.
2 The CHAP Secret Setup screen appears. In the Enter a secure secret field,
enter a secret code that includes 12 to 16 characters and click OK.
NOTE:
This Initiator CHAP secret and the Target CHAP secret must be different.
3 Before you can log on to the Target, you must set the Initiator CHAP
secret in the Target. Therefore, you must complete Target settings and
then log on to the iSCSI Initiator.
