2. To optionally configure CHAP authentication you should update the iSCSI Authentication details in the web management GUI, as shown below. Once the HP StorageWorks D2D Backup System has been modified, the operating system should be modified as follows for each available target discovered in step 1: NOTE: In the following commands, items in parentheses are user-defined strings. Substitute the appropriate information for , and . localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update --name node.session.auth.authmethod --value CHAP localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update --name node.session.auth.username --value localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update --name node.session.auth.password --value If the target is required to logon to the Initiator then the following two commands are also required: localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update --name node.session.auth.username_in --value localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update --name node.session.auth.password_in --value 3. The iSCSI nodes may be configured to log in automatically on system startup. The configuration settings for each available target are modified as follows: localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --op update --name node.conn[0].startup --value automatic 4. The Linux host must now log in to each iSCSI target device. This is done using the three command, where the IQN value matches those returned by the iscsiadm discovery command above: localhost:~ $ iscsiadm --mode node --targetname --portal x.x.x.x:3260 --login D2D Backup System 19
