HP 3PAR Ubuntu Operating System Implementation Guide

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 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

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.

1. Verify that a host definition has been created on the HP 3PAR StoreServ Storage. The following

example uses host_secret0 for the host CHAP password and target_secret0 for the

target CHAP password.

NOTE: The following example uses the host CHAP password host_secret0 for the host.

Be aware that CHAP secret must be at least 12 characters long.
