Install the iSCSI Initiator Software (iSCSI-attached Host Servers Only) Your Dell™ Model TL24iSCSIxSAS 1Gb iSCSI to SAS™ bridge requires an iSCSI initiator installed in the host server. The initiator needed will depend on your host server operating system. The information in this document provides relevant information on iSCSI initiator installation and configuration. For further information and latest documentation consult www.dell.
PAGE 4
Installing the iSCSI Initiator on a RHEL 5 System You can install the iSCSI initiator software on Red Hat Enterprise Linux 5 systems either during or after operating system installation. With this version of the Linux software, you can also elect to install the iSCSI initiator after the operating system installation via the command line. Installing the iSCSI initiator during RHEL 5 installation: 1) When the Package Installation Defaults screen is displayed, select the Customize now option.
PAGE 5
Installing the iSCSI Initiator on a SLES 10 SP1 System You can install the iSCSI initiator software on SUSE Linux Enterprise Server Version 10 systems either during or after operating system installation. Install the iSCSI initiator during SLES 10 SP1 installation: 1) 2) 3) 4) 5) 6) At the YaST Installation Settings screen, click Change. Click Software, then select Search. In the Search box, enter iscsi. When the open-iscsi and yast2-iscsi-client modules are displayed, select them. Click Accept.
PAGE 6
Using Linux Server Configuration of the iSCSI initiator for Red Hat® Enterprise Linux® version 4 and SUSE® Linux Enterprise Server 9 distributions is performed by modifying the /etc/iscsi.conf file, which is installed by default when you installed the iSCSI initiator. The /etc/iscsi.conf file needs to be changed before using the initiator: 1) Edit the /etc/iscsi.
PAGE 7
Using Windows Server 2003 or Windows Server 2008 GUI version 1) Click Start −>Programs−>Microsoft iSCSI Initiator or Start −>All Programs−>Administrative Tools−> iSCSI Initiator. 2) If you are using mutual CHAP authentication: a) Click the General tab b) Select Secret c) Enter a secure secret, enter the mutual CHAP secret you entered for the iSCSI to SAS bridge 3) Click the Discovery tab. 4) Under Target Portals, select the IP address of the iSCSI port on iSCSI bridge and click Remove.
PAGE 8
Note: If you are configuring Mutual CHAP authentication in Linux, you must also add an IncomingUsername= and IncomingPassword= entry after each OutgoingPassword= entry. The IncomingUsername is the iSCSI target name, which can be viewed in the iSCSI bridge management interface For example, your edited /etc/iscsi.conf file might look like this: DiscoveryAddress=172.168.10.6 OutgoingUsername=iqn.1987-05.com.cisco:01.742b2d31b3e OutgoingPassword=0123456789abcdef IncomingUsername=iqn.1984-05.com.dell:powervault.

) 10) 11) 12) 13) If you are using CHAP authentication, enter the CHAP username and password. To enable Mutual CHAP, select and enter the Mutual CHAP username and password. Repeat step 7 for each target until at least one connection is logged in for each controller. Go to Connected Targets. Verify that the targets are connected and show a status of true.

They can be replaced with an asterisk (*) if CHAP is not used. is 0, indicating that no mappings are specified and no further parameters are required. * * * An asterisk (*) represents the default value of a parameter.

Windows Host Setup If you are using a Windows host network, the following section provides a framework for preparing your network for iSCSI. To set up a Windows host network, you must configure the IP address and netmask of each iSCSI port connected to the iSCSI to SAS Bridge. The specific steps depend on whether you are using a Dynamic Host Configuration Protocol (DHCP) server, static IP addressing, Domain Name System (DNS) server, or Windows Internet Name Service (WINS) server.

Linux Host Setup If you are using a Linux host network, the following section provides a framework for preparing your network for iSCSI. To set up a Linux host network, you must configure the IP address and netmask of each iSCSI port connected to the .The specific steps depend on whether you are configuring TCP/IP using Dynamic Host Configuration Protocol (DHCP) or configuring TCP/IP using a static IP address.

Note: every time you restart the iscsi services, all the sessions will be opened back up again. Also, the session ID’s change, so it will be necessary to go back thru the steps above to kill the new iscsi sessions. Avoiding duplicate iSCSI devices discovered by RH4 To avoid logging in to multiple devices that were identified in a iSCSI Discovery (i.e., when starting the iSCSI services), make the following changes to your RedHat 4 iscsi.conf file located in the /etc directory.

6) Re-configure your iSCSI initiator 7) Re-configure you ISV Note: To delete the targets in Linux use the command below: iscsiadm --mode node –T iqn.1988-11.com.dell.2000eb:eui.5000e11116c35003.0 --op=delete iscsiadm --mode node –T iqn.1988-11.com.dell.2000eb:eui.5000e11116c35003.

Reference information Terminology CHAP (Challenge Handshake Authentication Protocol). An optional security protocol used to control access to an iSCSI storage system by restricting use of the iSCSI data ports on both the host server and iSCSI to SAS Bridge. For more information on the types of CHAP authentication supported, see Understanding CHAP Authentication. Host server port iSCSI port on the host server used to connect it to bridge.
