iSCSI initiator-to-VT authentication configuration 12 4. Enter the iscsiCfg --enable ddset command with the -n option to enable the DDSet: switch:admin> iscsicfg --enable ddset -n ddset-engineering This will enable the DDSet specified. Continue (yes, y, no, n) [n]: y The operation completed successfully. iSCSI initiator-to-VT authentication configuration Fabric OS v6.1.0 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. Enter 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. Enter 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, enter 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. Enter the isciCfg --addusername tgt command with the -t and -u options to bind a user name: Fabric OS Administrator's Guide 273 53-1001336-01
