Page 7: Introduction
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. -

(through failure of a host server port, for example) does not result in total loss of access to data on the storage array. -
Page 9: Hardware Installation
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. -
Page 10: Cabling The Enclosure
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. - Page 11 Figure 2-1.

- Page 12 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.

Page 15: Attaching Md1000 Expansion Enclosures
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. -
Page 16: Expanding With Previously Configured Md1000 Enclosures
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. -

Page 35: Configuring Iscsi On Your Storage Array
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. -
Page 36: Step 1: Discover The Storage Array (Out-Of-Band Management Only)
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... -

Page 39: Step 2: Configure The Iscsi Ports On The Storage 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. -
Page 40: Step 3: Perform Target Discovery From The Iscsi Initiator
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. -
Page 41: If You Are Using Linux Server
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. -

Page 45: Understanding Chap Authentication
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. -
Page 46: Chap Definitions
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. -
Page 47: Step 5: Configure Chap Authentication On The Storage Array (Optional)
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. -
Page 48: Configuring Mutual Chap Authentication On The Storage Array
