4.2 Setting Up Automatic iSCSI Service

The iSCSI service must be set to automatically activate when the Linux server starts up.

Add the following line to the end of the "/etc/iscsi/iscsid.conf" file:

4.3 Setting Up CHAP Authentication

If CHAP authentication is to be used, set it up according to the procedures that follow.

If CHAP authentication is not required, these procedures are not required.

There are two types of CHAP authentication: unidirectional and bidirectional.

For both types, the appropriate CHAP authentication setting is required for the ETERNUS Disk

storage system.

4.3.1 Setting Up Unidirectional CHAP Authentication

Create the accounts used by the iSCSI initiator to connect to the target.

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

node.conn[0].startup = automatic

The actual "username" and "pa ssword" must match those of the server 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).

node.session.auth.password = <
