HP 3PAR RedHat and Oracle Linux Implementation Guide

For HP 3PAR OS 3.1.x and OS 2.3.x, the output shows:
# showhost
Id Name Persona ----------WWN/iSCSI_Name----------- Port
0 redhatlinux Generic iqn.1994-05.com.redhat:a3df53b0a32d ---
For HP 3PAR OS 2.2.x, the output shows:
# showhost
Id Name -----------WWN/iSCSI_Name------------ Port
0 linux iqn.1994-05.com.redhat:a3df53b0a32d --
iqn.1994-05.com.redhat:a3df53b0a32d
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.
• Set the host CHAP secret.
# sethost initchap -f host_secret0 redhatlinux
• Verify the host CHAP secret.
# showhost -chap
Id Name -Initiator_CHAP_Name- -Target_CHAP_Name-
0 redhatlinux redhatlinux --
Setting the Host CHAP for RHEL 6 or RHEL 5
To set the host CHAP for RHEL 6 or RHEL 5, complete the following steps:
1. Go to the iSCSI Initiator host console, or, at a terminal, edit the /etc/iscsi/iscsid.conf
file and enable CHAP authentication:
#To enable CHAP authentication set node.session.auth.authmethod
#to CHAP. The default is None.
node.session.auth.authmethod = CHAP
2. Configure the host CHAP password for the discovery and login session by again editing the
configuration file /etc/iscsi/iscsid.conf file.
#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 = redhatlinux
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 = redhatlinux
node.session.auth.password = host_secret0
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.
