52 Setting Up Your iSCSI Storage Array
If you are using RHEL 5 or SLES 10 SP1
1
To enable CHAP (optional), the following line needs to be enabled in your
/etc/iscsi/iscsid.conf
file.
node.session.auth.authmethod = CHAP
2
To set a username and password for CHAP authentication of the initiator by the target(s), edit the
following lines as shown:
node.session.auth.username = <

iscsi_initiator_username

>
node.session.auth.password = <

CHAP_initiator_password

>
3
If you are using Mutual CHAP authentication, you can set the username and password for CHAP
authentication of the target(s) by the initiator by editing the following lines:
node.session.auth.username_in= <

iscsi_target_username

>
node.session.auth.password_in = <

CHAP_target_password

>
4
To set up discovery session CHAP authentication, first uncomment the following line:
discovery.sendtargets.auth.authmethod = CHAP
5
Set a username and password for a discovery session CHAP authentication of the initiator by the
target(s) by editing the following lines:
discovery.sendtargets.auth.username = <

iscsi_initiator_username

>
discovery.sendtargets.auth.password = <

CHAP_initiator_password

>
6
To set the username and password for discovery session CHAP authentication of the target(s) by the
initiator for Mutual CHAP, edit the following lines:
discovery.sendtargets.auth.username = <

iscsi_target_username

>
discovery.sendtargets.auth.password_in = <

CHAP_target_password

>
7
As a result of steps 1 through 6, the final configuration contained in the
/etc/iscsi/iscsid.conf
file might
look like this:
node.session.auth.authmethod = CHAP
node.session.auth.username = iqn.2005-03.com.redhat01.78b1b8cad821
node.session.auth.password = password_1
node.session.auth.username_in= iqn.1984-
05.com.dell:powervault.123456
node.session.auth.password_in = test1234567890
discovery.sendtargets.auth.authmethod = CHAP
discovery.sendtargets.auth.username = iqn.2005-
03.com.redhat01.78b1b8cad821
