Changing the iSCSI target authentication

1. In the AMW, select the Setup tab.
2. Select Manage iSCSI Settings.
   The Manage iSCSI Settings window is displayed and by default, the Target Authentication tab is selected.
3. To change the authentication settings, select:
   • None — If you do not require initiator authentication. If you select None, any initiator can access the target.
   • CHAP — To enable an initiator that tries to authenticate the target using Challenge Handshake Authentication Protocol (CHAP). Define the CHAP secret only if you want to use mutual CHAP authentication. If you select CHAP, but no CHAP target secret is defined, an error message is displayed. See Creating CHAP Secrets.
4. To enter the CHAP secret, click CHAP secret.
   The Enter Target CHAP Secret dialog is displayed.
5. Enter the Target CHAP secret.
   The Target CHAP secret must be at least 12 characters and up to 57 characters.
6. Enter the exact target CHAP secret in Confirm target CHAP secret.
   NOTE: If you do not want to create a CHAP secret, you can generate a random CHAP secret automatically. To generate a random CHAP secret, click Generate Random CHAP Secret.
7. Click OK.
   NOTE: You can select the None and CHAP at the same time, for example, when one initiator may not have CHAP and the other initiator has only CHAP selected.
