Configuring Chap Authentication Using Linux; Configure Chap Authentication On The Host Server Using Suse Linux Enterprise Server Gui - Dell PowerVault MD3800i Series Deployment Manual

5. Remove the target portal that you configured on the storage array during target discovery:
iscsicli RemoveTargetPortal <IP_address> <TCP_listening_port>.
6. Add the target portal with CHAP defined: iscsicli QAddTargetPortal
<IP_address_of_iSCSI_port_on_storage_array> [CHAP_username] [CHAP_password].
where, [CHAP_username] is the initiator name and [CHAP_password] is the target CHAP secret.
If you require a discovery session failover, repeat step 5 for all iSCSI ports on the storage array.
Otherwise, single-host port configuration is sufficient.

Configuring CHAP Authentication Using Linux

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 user name and password for CHAP authentication of the initiator by the target(s), edit the
following lines: 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 user name 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 user name 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 user name 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. 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
discovery.sendtargets.auth.password = password_1
discovery.sendtargets.auth.username = iqn.1984- 05.com.dell:powervault.
123456 discovery.sendtargets.auth.password_in = test1234567890.
