HP 3PAR SUSE Linux Enterprise Implementation Guide

1. Perform the CHAP configuration settings for the host initiator:

# 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. Perform the CHAP configuration setting for the target:

#To set a discovery session CHAP username and password for the initiator #authentication by the target(s), uncomment

the following lines:

discovery.sendtargets.auth.username = SuSElinux

discovery.sendtargets.auth.password = host_secret0

#To set a CHAP username and password for initiator

#authentication by the target(s), uncomment the following lines:

node.session.auth.username = SuSElinux

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.
