How to configure the Open-iSCSI module using the D2Dsetup script

Use the D2Dsetup script provided with the installation media to configure the Open-iSCSI module

automatically. You must provide the IP address as a parameter to the script.

localhost:~ $ D2Dsetup <IP_address>

If you wish to configure CHAP authentication, you should also provide the user name and password

for the initiator and the target, if required.

localhost:~ $ D2Dsetup <Initiator_CHAP_Username> <Initiator_CHAP_Password>

<Target_CHAP_Username> <Target_CHAP_Password> <IP_address>
