HP 3PAR RedHat and Oracle Linux Implementation Guide

1. Go to the iSCSI Initiator host console, or, at a terminal, edit the /etc/iscsi/iscsid.conf
file and configure the host and target CHAP passwords.
DiscoveryAddress=10.0.0.10
DiscoveryAddress=10.0.0.20
OutgoingUsername=redhatlinux
OutgoingPassword=host_secret0
DiscoveryAddress=10.0.0.10
DiscoveryAddress=10.0.0.20
IncomingUsername=S4121
IncomingPassword=target_secret0
NOTE: Notice that two DiscoveryAddress variables with the same IP address for the
HP 3PAR StoreServ Storage iSCSI target port are required: one for the host CHAP username
and password variables (OutgoingUsername and OutgoingPassword) and another one
for target CHAP username and password variables (IncomingUsername and
IncomingPassword).
NOTE: You can choose the OutgoingUsername and IncomingUsername variables, but
the OutgoingPassword and IncomingPassword must match the host CHAP password
and target CHAP password configured on the HP 3PAR StoreServ Storage.
Required
The variables under the DiscoveryAddress variable must be offset with a space in order
for the variables not to be global and to apply only to the specific DiscoveryAddress
above them.
2. Start or restart the iscsid daemon with the script /etc/init.d/iscsi.
3. Check to see if the iscsid daemon is running by using the script /etc/init.d/iscsi
status.
# /etc/init.d/iscsi status
iscsid (pid 30532 30529) is running... (RedHat 4)

NOTE: RHEL has documented a bug that can prevent an iSCSI host from rebooting (bug#
583218). RHEL has published a patch for the bug at the following location:

Configuring and Using Internet Storage Name Server
A dedicated IP network is preferable in configuring Internet Storage Name Server (iSNS).
NOTE: Secondary iSNS servers are not supported.
DHCP is not supported on iSCSI configurations.
Using a Microsoft iSNS Server to Discover Registrations
A Microsoft iSNS Server can be used to discover the iSCSI initiator and iSCSI targets on a dedicated
network.
Use the Windows 2008 Add Features wizard to add the iSNS feature, and then use the iSNS to
discover registrations.
