Introduction This guide outlines the steps for configuring the Dell™ PowerVault™ Modular Disk 3000i (MD3000i). The guide also covers installing the MD Storage Manager software, installing and ® configuring the Microsoft iSCSI and Linux initiators, and accessing documentation from the PowerVault MD3000i Resource CD.
Hardware Installation This chapter provides guidelines for planning the physical configuration of your Dell™ PowerVault™ MD3000i storage array and for connecting one or more hosts to the array. For complete information on hardware configuration, see the Dell™ PowerVault™ MD3000i Hardware Owner’s Manual.
Cabling the Enclosure You can connect up to 16 hosts and two expansion enclosures to the storage array. To plan your configuration, complete the following tasks: 1 Evaluate your data storage needs and administrative requirements. 2 Determine your hardware capabilities and how you plan to organize your data. 3 Calculate your requirements for the availability of your data.

In Figure 2-3, up to two servers are directly attached to the MD3000i RAID controller module. If the host server has a second Ethernet connection to the array, it can be attached to the iSCSI ports on the array’s second controller. This configuration provides improved availability by allowing two separate physical paths for each host, which ensures full redundancy if one of the paths fail.

Ensure that all MD1000 expansion enclosures being connected to the MD3000i are first updated to the latest Dell MD1000 EMM Firmware (available from support.dell.com). Dell MD1000 EMM Firmware versions prior to A03 are not supported in an MD3000i array; attaching an MD1000 with unsupported firmware causes an uncertified condition to exist on the array.
Expanding with Previously Configured MD1000 Enclosures Use this procedure if your MD1000 is now directly attached to and configured on a Dell PERC 5/E system. Data from virtual disks created on a PERC 5 SAS controller cannot be directly migrated to an MD3000i or to an MD1000 expansion enclosure connected to an MD3000i.
For more information, refer to the Dell™ PowerVault™ MD3000i Support Matrix available on support.dell.com. Install or update (to the latest version available on support.dell.com) the MD Storage Manager on each host server. Install or update (to the latest version available on support.dell.com) the multipath drivers on each host server.
4 Turn on attached units: Turn on the MD1000 expansion enclosure(s). Wait for the enclosure status LED to light blue. Turn on the MD3000i and wait for the status LED to indicate that the unit is ready: • If the status LEDs light a solid amber, the MD3000i is still coming online. •...

Array Setup and iSCSI Configuration To use the storage array, you must configure iSCSI on both the host server(s) and the storage array. Step-by-step instructions for configuring iSCSI are described in this section. However, before proceeding here, you must have already installed the Microsoft iSCSI initiator and the MD Storage Manager software.
Configuration Worksheet The iSCSI Configuration Worksheet (Table 4-2 or Table 4-3) helps you plan your configuration. Recording host server and storage array IP addresses at a single location will help you configure your setup faster and more efficiently. Guidelines for Configuring Your Network for iSCSI provides general network setup guidelines for both Windows and Linux environments.

Using iSNS iSNS (Internet Storage Naming Service) Server, supported only on Windows iSCSI environments, eliminates the need to manually configure each individual storage array with a specific list of initiators and target IP addresses. Instead, iSNS automatically discovers, manages, and configures all iSCSI devices in your environment.
By default, the storage array management ports will be set to DHCP configuration. If the controller(s) on your storage array is unable to get IP configuration from a DHCP server, it will timeout after ten seconds and fall back to a default static IP address. The default IP configuration is: Controller 0: IP: 192.168.128.101 Subnet Mask: 255.255.255.0...
Tasks dialog box or click the Tools tab and choose Blink. Lights on the front of the storage array blink intermittently to identify the array. Dell recommends blinking storage arrays to ensure that you are working on the correct enclosure. Set a storage array password.
Table 4-5. Initial Storage Array Setup Tasks (continued) Task Set the management port IP addresses on each controller. Set up alert notifications. Set up e-mail alerts. Set up SNMP alerts. NOTE: The Status area in the Summary tab shows if alerts have been set for the selected array.
The TCP listening port for the iSNS server is the port number the storage array controller uses to connect to an iSNS server. This allows the iSNS server to register the iSCSI target and portals of the storage array so that the host server initiators can identify them.
Step 3: Perform Target Discovery from the iSCSI Initiator This step identifies the iSCSI ports on the storage array to the host server. Select the set of steps in one of the following sections (Windows or Linux) that corresponds to your operating system.
Configuration of the iSCSI initiator for Red Hat Enterprise Server 9 distributions is performed by modifying the /etc/iscsi.conf file, which is installed by default when you install MD Storage Manager. You can edit the file directly, or replace the default file with a sample file included on the MD3000i Resource CD.
6 Restart the iSCSI daemon by executing the following command from the console: /etc/init.d/iscsi restart 7 Verify that the server can connect to the storage array by executing this command from a console: iscsi -ls If successful, an iSCSI session has been established to each iSCSI port on the storage array. Sample...
4 Edit the following entries in the /etc/iscsi/iscsid.conf file: Edit (or verify) that the node.startup = manual line is disabled. Edit (or verify) that the node.startup = automatic line is enabled. This will enable automatic startup of the service at boot time. Verify that the following time-out value is set to 144: node.session.timeo.replacement_timeout = 144 Save and close the /etc/iscsi/iscsid.conf file.
Click Next. 6 Choose whether or not the host server will be part of a host server group that will share access to the same virtual disks as other host servers. Select Yes only if the host is part of a Microsoft cluster.
In target CHAP , the storage array authenticates all requests for access issued by the iSCSI initiator(s) on the host server via a CHAP secret. To set up target CHAP authentication, you enter a CHAP secret on the storage array, then configure each iSCSI initiator on the host server to send that secret each time it attempts to access the storage array.
The next two steps in your iSCSI configuration, Step 5: Configure CHAP Authentication on the Storage Array (optional) and Step 6: Configure CHAP Authentication on the Host Server (optional), offer step-by- step procedures for setting up CHAP on your storage array and host server.
If you are configuring CHAP authentication of any kind (either target-only or target and mutual), you must complete this step and Step 6: Configure CHAP Authentication on the Host Server (optional). If you are not configuring any type of CHAP , skip these steps and go to Step 7: Connect to the Target Storage Array from the Host Server.
Configuring Mutual CHAP Authentication on the Storage Array The initiator secret must be unique for each host server that connects to the storage array and must not be the same as the target CHAP secret. 1 From MD Storage Manager, click on the iSCSI tab, then select Enter Mutual Authentication Permissions.
Select the set of steps in one of the following sections (Windows or Linux) that corresponds to your operating system. If you are using Windows Server 2003 or Windows Server 2008 GUI version 1 Click Start→ Programs→ Microsoft iSCSI Initiator or Start→ All Programs→ Administrative Tools→...
If the connection fails, make sure that all IP addresses are entered correctly. Mistyped IP addresses are a common cause of connection problems. If you are using Windows Server 2008 Core Version 1 Set the iSCSI initiator services to start automatically (if not already set): sc \\<server_name>...
DiscoveryAddress=220.127.116.11 OutgoingUsername=iqn.1987-05.com.cisco:01.742b2d31b3e OutgoingPassword=0123456789abcdef If you are using Mutual CHAP authentication on Linux Server 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 MD Storage Manager by accessing the iSCSI tab and clicking Change Target Identification.
7 As a result of steps 1 through 6, the final configuration contained in the /etc/iscsi/iscsid.conf file might look like this: node.session.auth.authmethod = CHAP node.session.auth.username = iqn.2005-03.com.redhat01.78b1b8cad821 node.session.auth.password = password_1 node.session.auth.username_in= iqn.1984- 05.com.dell:powervault.123456 node.session.auth.password_in = test1234567890 discovery.sendtargets.auth.authmethod = CHAP discovery.sendtargets.auth.username = iqn.2005- 03.com.redhat01.78b1b8cad821 Setting Up Your iSCSI Storage Array...

7 Click OK. To support storage array controller failover, the host server must be connected to at least one iSCSI port on each controller. Repeat step 3 through step 8 for each iSCSI port on the storage array that you want to establish as failover targets (the Target Portal address will be different for each port you connected to).
If you are using Windows Server 2008 Core Version 1 Set the iSCSI initiator services to start automatically (if not already set): sc \\<server_name> config msiscsi start= auto 2 Start the iSCSI service (if necessary): sc start msiscsi 3 Log on to the target: iscsicli PersistentLoginTarget <...
/etc/init.d/iscsi restart Verify that the host server is able to connect to the storage array by running the iscsi -ls command as you did in target discovery. If the connection is successful, an iSCSI session will be established to each iSCSI port on the storage array.
Disconnected or Unconfigured, respectively, check the following and repeat the iSCSI configuration steps: • Are all cables securely attached to each port on the host server and storage array? • Is TCP/IP correctly configured on all target host ports? •...
