iSCSI initiator-to-VT authentication configuration Fabric OS 5.2.0 or later supports both one-way and mutual CHAP authentication for iSCSI initiator-to-iSCSI VT target sessions. The authentication method (CHAP or none) is set on a per-iSCSI VT basis. Setting the user name and shared secret Authentication depends on a user name and shared secret. When an iSCSI VT authenticates an iSCSI initiator, it checks the user name and shared secret against all configured CHAP values. To enforce authentication of iSCSI initiators, set each iSCSI VT authentication to CHAP. The iSCSI initiator can use any user name and shared secret for any iSCSI VT configured on the fabric. 1. Connect and log in to the switch. 2. Issue the iscsiCfg --create auth command with the -u and -s options to configure a user name and shared secret: switch:admin> iscsicfg --create auth -u username0001 -s usersecret0001 The operation completed successfully. 3. Issue the iscsiCfg --modify tgt command with the -t and -a options to set CHAP as the authentication method: switch:admin> iscsicfg --modify tgt -t iqn.2006-10.com.brocade:example-disk001 -a CHAP The operation completed successfully. 4. To verify that CHAP is enabled for the iSCSI VT, issue the iscsiCfg --show tgt command with the -t and -v options: switch:admin> iscsicfg --show tgt -t iqn.2006-10.com.brocade:example-disk001 -v Number of records found: 1 Name: iqn.2006-10.com.brocade:example-disk001 State/Status: Online/Defined Auth. Method: CHAP Binding user names to an iSCSI VT For additional security, you can bind specific user names to an iSCSI VT. When you do this, the specific user name and CHAP secret combination is required for authentication during the iSCSI login phase. The maximum number of user names that can be bound per iSCSI VT is 16. 1. Connect and log in to the switch. 2. Issue the isciCfg --addusername tgt command with the -t and -u options to bind a user name: switch:admin> iscsicfg --addusername tgt -t iqn.2002-10.com.brocade:tgt -u "isisctgt1;hello123" This operation completed successfully 3. Issue the iscsiCfg --commit all command. 4. Issue the iscsiCfg --show tgt command with the -t and -v options to verify that a user name has been bound to the iSCSI VT: switch:admin> iscsicfg --show tgt -t iqn.2002-10.com.brocade:tgt -v Number of records found: 1 Name: iqn.2002-10.com.brocade:tgt1 CHAP Users CHAP Status 1. iscsitgt1 Online/Committed 2. hello123 Invalid Fabric OS 6.1.x administrator guide 273
