To set a user name and password for CHAP authentication of the initiator by the target(s), edit the following lines:node.session.auth.username = node.session.auth.password = 3. If you are using Mutual CHAP authentication, you can set the user name and password for CHAP authentication ofthe target(s) by the initiator by editing the following lines:node.session.auth.username_in=node.session.auth.password_in =4. To set up discovery session CHAP authentication, first uncomment the following line:discovery.sendtargets.auth.authmethod = CHAP5. Set a user name and password for a discovery session CHAP authentication of the initiator by the target(s) byediting the following lines:discovery.sendtargets.auth.username =discovery.sendtargets.auth.password =6. To set the user name and password for discovery session CHAP authentication of the target(s) by the initiator forMutual CHAP, edit the following lines:discovery.sendtargets.auth.username = discovery.sendtargets.auth.password_in = 7. The final configuration contained in the /etc/iscsi/iscsid.conf file may look like this:node.session.auth.authmethod = CHAPnode.session.auth.username = iqn.2005- 03.com.redhat01.78b1b8cad821node.session.auth.password = password_1node.session.auth.username_in= iqn.1984- 05.com.dell:powervault.123456node.session.auth.password_in = test1234567890discovery.sendtargets.auth.authmethod = CHAPdiscovery.sendtargets.auth.username = iqn.2005-03.com.redhat01.78b1b8cad821 discovery.sendtargets.auth.password =password_1discovery.sendtargets.auth.username = iqn.1984- 05.com.dell:powervault.123456discovery.sendtargets.auth.password_in = test1234567890For SUSE Linux Enterprise Server SP3 Using The GUI1.
