node.session.auth.password = host_secret0

#To set a discovery session CHAP username and password for target(s)

# authentication by the initiator, uncomment the following lines:

discovery.sendtargets.auth.username_in = S121

discovery.sendtargets.auth.password_in = target_secret0

# To set a CHAP username and password for target(s)

# authentication by the initiator, uncomment the following lines:

node.session.auth.username_in = S121

node.session.auth.password_in = target_secret0

NOTE: S121 is the target CHAP name, which can be displayed on the HP 3PAR StoreServ

Storage by running the showhost -chap command.

NOTE: The OutgoingUsername and IncomingUsername variables on the host should

each be set to the same name as shown in the showhost -chap output. The names are

case-sensitive. If the names do not match, an authentication error occurs. Similarly, the

OutgoingPassword and IncomingPassword must match the host CHAP password and

target CHAP password configured on the HP 3PAR StoreServ Storage.

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

the iscsiadm Command” (page 15).

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 and start the open-iscsi daemon:

# /etc/init.d/open-iscsi stop

Logout 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 Ubuntu Using the

iscsiadm Command” (page 15) to rediscover the iSCSI target nodes and create the iSCSI
