HP 3PAR SUSE Linux Enterprise Implementation Guide

1. Go to the iSCSI Initiator host console, or, at a terminal, edit the /etc/iscsid.conf file

and enable CHAP authentication:

# To enable CHAP authentication for a discovery session to the target

# set discovery.sendtargets.auth.authmethod to CHAP. The default is None.

discovery.sendtargets.auth.authmethod = CHAP

# To enable CHAP authentication set node.session.auth.authmethod

# to CHAP. The default is None.

node.session.auth.authmethod = CHAP

2. Configure the host CHAP password for the discovery and login session by again editing the

configuration file /etc/iscsid.conf file.

NOTE: The OutgoingUsername variable can be set to anything you want, but the

OutgoingPassword has to be the same as the host CHAP secret configured on the HP 3PAR

StoreServ Storage.

3. Perform discovery and login as described in “Creating the iSCSI Connection in SUSE Using

the iscsiadm Command” (page 40).

If the targets have been discovered previously, you must logout of the iSCSI sessions, delete

the node and send target records before performing discovery and login by completing the

following steps:

a. Stop the open-iSCSI daemon:

# /etc/init.d/open-iscsi stopLogout session [0][10.1.1.100:3260 iqn.2000-05.com.3pardata:20110002ac0001a6"]

Logout session [1][10.0.0.200:3260 iqn.2000-05.com.3pardata:21110002ac0001a6]

done

Stopping iSCSI initiator service: done

b. Delete the target node records:

/etc/iscsi/nodes/#rm -r iqn.2000-05.com.3pardata:20110002ac0001a6

c. Delete the send_target records:

/etc/iscsi/send_targets/#rm 10.0.0.200,3260

d. Start the open-iscsi daemon:

/etc/init.d/open-iscsi start

Starting iSCSI initiator service: done

Setting up iSCSI targets: done

e. Repeat the steps as described in “Creating the iSCSI Connection in SUSE Using the

iscsiadm Command” (page 40) to rediscover the iSCSI target nodes and create the iSCSI

Setting Up the Bidirectional CHAP on the HP 3PAR StoreServ Storage

To set bidirectional CHAP (mutual), complete the following steps. The HP 3PAR OS CLI sethost

initchap and sethost targetchap commands must be used to set bidirectional CHAP on

the HP 3PAR StoreServ Storage.
