4.3.2 Setting Up Bidirectional CHAP Authentication

In addition to the unidirectional CHAP authentication accounts, additional accounts are required

to enable the target to connect to the initiator.

Add the following lines to the "/etc/iscsi/iscsid.conf" file:

4.4 Setting Up the Network Environment

Set the IP information (IP address and subnet mask) of the LAN card.

• "node.session.auth.username", "node.session.auth.password",

"discovery.sendtargets.auth.username", and

"discovery.sendtargets.auth.password" are initiator accounts.

"node.session.auth.username_in", "node.session.auth.password_in",

"discovery.sendtargets.auth.username_in", and

"discovery.sendtargets.auth.password_in" are target accounts.

Every such initiator and target account must be assigned a unique

name.

• The Initiator "username" and "password" must match those of the server

set in the ETERNUS Disk storage system. The Target "username" and

"password" must match those of the ETERNUS Disk storage system

port set in the ETERNUS Disk storage system. For details of the

ETERNUS Disk storage system settings, refer to

"Chapter 7 ETERNUS

Disk Storage System Logical Unit Recognition" (page 19).

The LAN card should be set to use the same subnet as that set for the

ETERNUS Disk storage system that is being connected to. For details of

the ETERNUS Disk storage system settings, refer to

"Chapter 7 ETERNUS
