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. Other information provided includes system requirements,  
storage array organization, initial software startup and verification, and discussions of utilities and  
premium features.  
MD Storage Manager enables an administrator to configure and monitor storage arrays for optimum  
®
®
usability. MD Storage Manager operates on both Microsoft Windows and Linux operating  
systems and can send alerts about storage array error conditions by either e-mail or Simple Network  
Management Protocol (SNMP). These alerts can be set for instant notification or at regular intervals.  
System Requirements  
Before installing and configuring the MD3000i hardware and MD Storage Manager software, ensure  
that the operating system is supported and minimum system requirements are met. For more  
information, refer to the Dell™ PowerVault™ MD3000i Support Matrix available on  
support.dell.com.  
Management Station Hardware Requirements  
A management station uses MD Storage Manager to configure and manage storage arrays across the  
network. Any system designated as a management station must be an x86-based system that meets  
the following minimum requirements:  
®
®
•
•
•
•
•
Intel Pentium or equivalent CPU (133 MHz or faster)  
128 MB RAM (256 MB recommended)  
120 MB disk space available  
Administrator or equivalent permissions  
Minimum display setting of 800 x 600 pixels with 256 colors (1024 x 768 pixels with 16-bit color  
recommended)

Introduction to Storage Arrays  
A storage array includes various hardware components, such as physical disks, RAID controller modules,  
fans, and power supplies, gathered into enclosures. An enclosure containing physical disks accessed  
through RAID controller modules is called a RAID enclosure.  
One or more host servers attached to the storage array can access the data on the storage array. You can  
also establish multiple physical paths between the host(s) and the storage array so that loss of any single  
path (through failure of a host server port, for example) does not result in total loss of access to data on the  
storage array.  
The storage array is managed by MD Storage Manager software running either on a host server or a  
dedicated management station. On a host server system, MD Storage Manager and the storage array  
communicate management requests and event information directly via iSCSI ports. On a dedicated  
management station, MD Storage Manager communicates with the storage array either through an  
Ethernet connection on the RAID controller modules or via the host agent installed on the host server.  
Using MD Storage Manager, you configure the physical disks in the storage array into logical components  
called disk groups, then divide the disk groups into virtual disks. You can make as many disk groups and  
virtual disks as your storage array configuration and hardware permit. Disk groups are created in the  
unconfigured capacity of a storage array, while virtual disks are created in the free capacity of a disk  
group.  
Unconfigured capacity is comprised of the physical disks not already assigned to a disk group. When a  
virtual disk is created using unconfigured capacity, a disk group is automatically created. If the only  
virtual disk in a disk group is deleted, the disk group is also deleted. Free capacity is space in a disk group  
that has not been assigned to a virtual disk.  
Data is written to the physical disks in the storage array using RAID technology. RAID levels define the  
way in which data is written to physical disks. Different RAID levels offer different levels of accessibility,  
redundancy, and capacity. You can set a specified RAID level for each disk group and virtual disk on your  
storage array.  
You can also provide an additional layer of data redundancy by creating disk groups that have a RAID  
level other than 0. Hot spares can automatically replace physical disks marked as Failed.  
For more information on using RAID and managing data in your storage solution, see the Dell™  
PowerVault™ Modular Disk Storage Manager User’s Guide.

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.  
Storage Configuration Planning  
Consider the following items before installing your storage array:  
•
•
•
•
Evaluate data storage needs and administrative requirements.  
Calculate availability requirements.  
Decide the frequency and level of backups, such as weekly full backups with daily partial backups.  
Consider storage array options, such as password protection and e-mail alert notifications for error  
conditions.  
•
Design the configuration of virtual disks and disk groups according to a data organization plan.  
For example, use one virtual disk for inventory, a second for financial and tax information, and a  
third for customer information.  
•
•
Decide whether to allow space for hot spares, which automatically replace failed physical disks.  
If you will use premium features, consider how to configure virtual disk copies and snapshot  
virtual disks.  
About the Enclosure Connections  
The RAID array enclosure is connected to an iSCSI-enabled host server via one or two RAID  
controller modules. The RAID controller modules are identified as RAID controller module 0 and  
RAID controller module 1 (see the PowerVault MD3000i Hardware Owner’s Manual for more  
information).  
Each RAID controller module contains two iSCSI In port connectors that provide direct connections  
to the host server or switches. iSCSI In port connectors are labeled In-0 and In-1(see the PowerVault  
MD3000i Hardware Owner’s Manual for more information).  
Each MD3000i RAID controller module also contains an Ethernet management port and a SAS Out  
port connector. The Ethernet management port allows you to install a dedicated management  
station (server or standalone system). The SAS Out port allows you to connect the RAID enclosure  
to an optional expansion enclosure (MD1000) for additional storage capacity.

The iSCSI interface provides many versatile host-to-controller configurations. For the purposes of this  
manual, the most conventional topologies are described. The figures in this chapter are grouped  
according to the following general categories:  
•

Direct-attached solutions  
Network-attached (SAN) solutions  
Redundancy vs. Nonredundancy  
Nonredundant configurations, configurations that provide only a single data path from a host to the  
RAID enclosure, are recommended only for non-critical data storage. Path failure from a failed or  
removed cable, a failed NIC, or a failed or removed RAID controller module results in loss of host access  
to storage on the RAID enclosure.  
Redundancy is established by installing separate data paths between the host and the storage array, in  
which each path is to different RAID controller modules. Redundancy protects the host from losing  
access to data in the event of path failure, because both RAID controllers can access all the disks in the  
storage array.  
Direct-Attached Solutions  
You can cable from the Ethernet ports of your host servers directly to your MD3000i RAID controller  
iSCSI ports. Direct attachments support single path configurations (for up to four servers) and dual path  
data configurations (for up to two servers) for both single and dual controller modules.  
Single Path Data Configurations  
With a single path configuration, a group of heterogeneous clients can be connected to the MD3000i  
RAID controller through a single physical Ethernet port. Because there is only the single port, there is no  
redundancy (although each iSCSI portal supports multiple connections). This configuration is  
supported for both single controller and dual controller modes.  
Figure 2-1 and Figure 2-2 show the supported nonredundant cabling configurations to MD3000i RAID  
controller modules using the single path data configuration. Figure 2-1 shows a single controller array  
configuration. Figure 2-2 shows how four standalone servers are supported in a dual controller array  
configuration.

Dual Path Data Configuration  
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.

Network-Attached Solutions  
You can also cable your host servers to the MD3000i RAID controller iSCSI ports through an IP storage  
area network (SAN) industry-standard 1GB Ethernet switch. By using an IP SAN "cloud" Ethernet  
switch, the MD3000i RAID controller can support up to 16 hosts simultaneously with multiple  
connections per session. This solution supports either single- or dual-path data configurations, as well as  
either single or dual controller modules.  
Figure 2-4 shows how up to 16 standalone servers can be attached (via multiple sessions) to a single  
MD3000i RAID controller module through a network. Hosts that have a second Ethernet connection to  
the network allow two separate physical paths for each host, which ensures full redundancy if one of the  
paths fail. Figure 2-5 shows how the same number of hosts can be similarly attached to a dual MD3000i  
RAID controller array configuration.

Attaching MD1000 Expansion Enclosures  
One of the features of the MD3000i is the ability to add up to two MD1000 expansion enclosures for  
additional capacity. This expansion increases the maximum physical disk pool to 45 3.5" SAS and/or  
SATA II physical disks.  
As described in the following sections, you can expand with either a brand new MD1000 or an MD1000  
that has been previously configured in a direct-attach solution with a PERC 5/E system.  
NOTICE: 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. See the following procedure for more information.

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.  
NOTICE: If an MD1000 that was previously attached to PERC 5 SAS controller is used as an expansion enclosure  
to an MD3000i, the physical disks of the MD1000 enclosure will be reinitialized and data will be lost. All data on the  
MD1000 must be backed up before attempting the expansion.  
Perform the following steps to attach previously configured MD1000 expansion enclosures to the MD3000i:  
1
2
Back up all data on the MD1000 enclosure(s).  
While the enclosure is still attached to the PERC 5 controller, upgrade the MD1000 firmware to  
version A03 or above. Windows systems users can reference the DUP.exe package; for Linux kernels,  
users can reference the DUP.bin package.

Installing MD Storage Software  
The MD3000i Storage Software provides the host-based storage agent, multipath driver, and MD  
Storage Manager application used to operate and manage the storage array solution. The MD Storage  
Manager application is installed on a host server to configure, manage, and monitor the storage array.  
When installing from the CD, three installation types are available:  
•
•
•
Typical (Full installation) — This package installs both the management station and host server  
software. It includes the necessary host-based storage agent, multipath driver, and MD Storage  
Manager software. Select this option if you plan to use MD Storage Manager on the host server to  
configure, manage, and monitor the storage array.  
Management Station  
—
This package installs the MD Storage Manager software, which is needed  
to configure, manage, and monitor the storage array. Select this option if you plan to us MD Storage  
Manager to manage the storage array from a standalone system that is connected to the storage  
array only via the Ethernet management ports.  
Host — This package installs the necessary storage agent and multipath driver on a host server  
connected to the storage array. Select this option on all host servers that are connected to a storage  
array but will NOT use MD Storage Manager for any storage array management tasks.  
NOTE: Dell recommends using the Host installation type if the host server is running Windows Server 2008  
Core version.  
Installing MD Storage Software on an iSCSI-attached Host Server (Windows)  
To install MD Storage Manager on a Windows system, you must have administrative privileges to install  
MD Storage Manager files and program packages to the C:\Program Files\Dell\MD Storage Manager  
directory.  
NOTE: A minimum version of the Storport driver must be installed on the host server before installing the MD  
Storage Manager software. A hotfix with the minimum supported version of the Storport driver is located in the  
\windows\Windows_2003_2008\hotfixes directory on the MD3000i Resource CD. The MD Storage Manager  
installation will test for the minimum Storport version and will require you to install it before proceeding.  
Complete the following steps to install MD Storage Manager on an iSCSI-connected host server:

monitor automatically or manually after rebooting. You should configure only one system (either a host  
or a management station) to automatically restart the event monitor.  
NOTE: The event monitor notifies the administrator of problem conditions with the storage array. MD Storage  
Manager can be installed on more than one system, but running the event monitor on multiple systems can  
cause multiple alert notifications to be sent for the same error condition. To avoid this issue, enable the event  
monitor only on a single system that monitors your storage arrays. For more information on alerts, the event  
monitor, and manually restarting the event monitor, see the User’s Guide.

NOTE: These registry files set the host up for the correct failback operation.  
15 If you have third-party applications that use the Microsoft Volume Shadow-copy Service (VSS) or Virtual  
Disk Service (VDS) Application Programming Interface (API), install the VDS_VSS package located in  
the windows\VDS_VSS directory on the MD3000i Resource CD. Separate versions for 32-bit and 64-bit  
operating systems are provided. The VSS and VDS provider will engage only if it is needed.  
16 Set the path for the command line interface (CLI), if required. See the MD Storage Manager CLI Guide  
for more information.  
17 Install MD Storage Manager on all other Windows hosts attached to the MD3000i array.  
18 If you have not yet cabled your MD3000i Storage Array, do so at this time.  
19 After the MD3000i has initialized, reboot each host attached to the array.  
NOTE: If you are not installing MD Storage Manager directly from the Resource CD (for example, if you are instead  
installing MD Storage Manager from a shared network drive), you must manually apply iSCSI updates to the  
Windows system registry. To apply these updates, go to the \windows\Windows_2003_2008\iSCSI_reg_changer  
directory on the Resource CD and run the iSCSi_reg_changer_Win2k3.bat or iSCSi_reg_changer_Win2k8.bat file.  
The iSCSI Initiator must be installed before you make these updates.

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. If you have not, refer to Software Installation and complete those procedures  
before attempting to configure iSCSI.  
NOTE: Although some of these steps shown in this section can be performed in MD Storage Manager  
from a management station, the iSCSI initiator must be installed and configured on each host server.  
Before You Start  
Before you begin configuring iSCSI, you should fill out the iSCSI Configuration Worksheet  
(Table 4-2 and Table 4-3). Gathering this type of information about your network prior to starting  
the configuration steps should help you complete the process in less time.  
NOTE: If you are running Windows Server 2008 and elect to use IPv6, use Table 4-3 to define your  
settings on the host server and storage array controller iSCSI ports. IPv6 is not supported on storage  
array controller management ports.

Configuring iSCSI on Your Storage Array  
The following sections contains step-by-step instructions for configuring iSCSI on your storage array.  
However, before beginning, it is important to understand where each of these steps occur in relation to  
your host server/storage array environment.  
Table 4-4 below shows each specific iSCSI configuration step and where it occurs.  
Table 4-4. Host Server vs. Storage Array  
This step is performed on the HOST SERVER using  
the Microsoft or Linux iSCSI Initiator:  
This step is performed on the STORAGE ARRAY  
using MD Storage Manager:  
Step 1: Discover the storage array  
Step 2: Configure the iSCSI ports on the storage  
array  
Step 3: Perform target discovery from the iSCSI  
initiator  
Step 4: Configure host access  
Step 5: (Optional) Configure CHAP  
authentication on the storage array  
Step 6: (Optional) Configure CHAP  
authentication on the host server  
Step 7: Connect to the storage array from the host  
server  
Step 8: (Optional) Set up in-band management  
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.  
For more information on iSNS, including installation and configuration, see www.microsoft.com.

Step 1: Discover the Storage Array (Out-of-band management only)  
Default Management Port Settings  
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  
Controller 1: IP: 192.168.128.102 Subnet Mask: 255.255.255.0  
NOTE: No default gateway is set.  
NOTE: If DHCP is not used, initial configuration of the management station must be performed on the same  
physical subnet as the storage array. Additionally, during initial configuration, at least one network adapter  
must be configured on the same IP subnet as the storage array’s default management port (192.168.128.101 or  
192.168.128.102). After initial configuration (management ports are configured using MD Storage Manager),  
the management station’s IP address can be changed back to its previous settings.  
NOTE: This procedure applies to out-of-band management only. If you choose to set up in-band  
management, you must complete this step and then refer to Step 8: (Optional) Set Up In-Band Management.  
You can discover the storage array automatically or manually. Choose one and complete the steps below.  
Automatic Storage Array Discovery  
1
Launch MD Storage Manager.  
If this is the first storage array to be set up, the Add New Storage Array window appears.

Choose Automatic and click OK  
.
It may take several minutes for the discovery process to complete. Closing the discovery status window  
before the discovery process completes will cancel the discovery process.  
After discovery is complete, a confirmation screen appears. Click Close to close the screen.  
Manual Storage Array Discovery  
1
Launch MD Storage Manager.  
If this is the first storage array to be set up, the Add New Storage Array window appears.  
2
3
Select Manual and click OK.  
Select Out-of-band management and enter the host server name(s) or IP address(es) of the iSCSI  
storage array controller.  
4
Click Add.  
Out-of-band management should now be successfully configured.  
After discovery is complete, a confirmation screen appears. Click Close to close the screen.

Step 2: Configure the iSCSI Ports on the Storage Array  
By default, the iSCSI ports on the storage array are set to the following IPv4 settings:  
Controller 0, Port 0: IP: 192.168.130.101 Subnet Mask: 255.255.255.0 Port: 3260  
Controller 0, Port 1: IP: 192.168.131.101 Subnet Mask: 255.255.255.0 Port: 3260  
Controller 1, Port 0: IP: 192.168.130.102 Subnet Mask: 255.255.255.0 Port: 3260  
Controller 1, Port 1: IP: 192.168.131.102 Subnet Mask: 255.255.255.0 Port: 3260  
NOTE: No default gateway is set.  
To configure the iSCSI ports on the storage array, complete the following steps:

2
From MD Storage Manager, click the iSCSI tab, then select Configure iSCSI Host Ports  
Configure the iSCSI ports on the storage array.  
.
NOTE: Using static IPv4 addressing is recommended, although DHCP is supported.  
NOTE: IPv4 is enabled by default on the iSCSI ports. You must enable IPv6 to configure IPv6 addresses.  
NOTE: IPv6 is supported only on controllers that will connect to host servers running Windows Server 2008.  
The following settings are available (depending on your specific configuration) by clicking the  
Advanced button:  
•
Virtual LAN (VLAN) support  
A VLAN is a network of different systems that behave as if they are connected to the same  
segments of a local area network (LAN) and are supported by the same switches and routers.  
When configured as a VLAN, a device can be moved to another location without being  
reconfigured. To use VLAN on your storage array, obtain the VLAN ID from your network  
administrator and enter it here.  
•
•
Ethernet priority  
This parameter is set to determine a network access priority.  
TCP listening port  
The port number the controller on the storage array uses to listen for iSCSI logins from host server  
iSCSI initiators.  
NOTE: 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.  
•
Jumbo frames  
Jumbo Ethernet frames are created when the maximum transmission units (MTUs) are larger than  
1500 bytes per frame. This setting is adjustable port-by-port.

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 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.  
To use the sample file included on the CD:

Save the default /etc/iscsi.conf file by naming it to another name of your choice.  
Copy the appropriate sample file from /linux/etc on the CD to /etc/iscsi.conf  
Rename the sample file to iscsi.conf  
.
.
Edit the iscsi.conf file and replace the IP address entries shown for DiscoveryAddress=with the  
IP addresses assigned to the iSCSI ports on your storage array:  
For example, if your MD3000i has two iSCSI controllers (four iSCSI ports), you will need to add four  
IP addresses:  
DiscoveryAddress=<your_storage_array_IP_address>  
DiscoveryAddress=<your_storage_array_IP_address>  
DiscoveryAddress=<your_storage_array_IP_address>  
DiscoveryAddress=<your_storage_array_IP_address>  
If you elect not to use the sample file on the CD, edit the existing default /etc/iscsi.conf file as shown  
in the previous example.

Understanding CHAP Authentication  
Before proceeding to either Step 5: Configure CHAP Authentication on the Storage Array (optional) or  
Step 6: Configure CHAP Authentication on the Host Server (optional), it would be useful to gain an  
overview of how CHAP authentication works.  
What is CHAP?  
Challenge Handshake Authentication Protocol (CHAP) is an optional iSCSI authentication method  
where the storage array (target) authenticates iSCSI initiators on the host server. Two types of CHAP are  
supported: target CHAP and mutual CHAP.  
Target CHAP  
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.  
Mutual CHAP  
In addition to setting up target CHAP, you can set up mutual CHAP in which both the storage array and  
the iSCSI initiator authenticate each other. To set up mutual CHAP, you configure the iSCSI initiator  
with a CHAP secret that the storage array must send to the host sever in order to establish a connection.  
In this two-way authentication process, both the host server and the storage array are sending  
information that the other must validate before a connection is allowed.  
CHAP is an optional feature and is not required to use iSCSI. However, if you do not configure CHAP  
authentication, any host server connected to the same IP network as the storage array can read from and  
write to the storage array.  
NOTE: If you elect to use CHAP authentication, you should configure it on both the storage array (using MD  
Storage Manager) and the host server (using the iSCSI initiator) before preparing virtual disks to receive data.  
If you prepare disks to receive data before you configure CHAP authentication, you will lose visibility to the  
disks once CHAP is configured.

CHAP Definitions  
To summarize the differences between target CHAP and mutual CHAP authentication, see Table 4-6.  
Table 4-6. CHAP Types Defined  
CHAP Type  
Description  
Target CHAP  
Sets up accounts that iSCSI initiators use to connect to the target  
storage array. The target storage array then authenticates the iSCSI  
initiator.  
Mutual CHAP  
Applied in addition to target CHAP, mutual CHAP sets up an account  
that a target storage array uses to connect to an iSCSI initiator. The  
iSCSI initiator then authenticates the target.  
How CHAP Is Set Up  
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.

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.  
NOTE: If you choose to configure mutual CHAP authentication, you must first configure target CHAP.  
Remember, in terms of iSCSI configuration, the term target always refers to the storage array.  
Configuring Target CHAP Authentication on the Storage Array  
1
From MD Storage Manager, click the iSCSI tab, then Change Target Authentication.  
Make a selection based on the following:  
Table 4-7. CHAP Settings  
Selection  
Description  
None  
This is the default selection. If None is the only selection, the storage array will  
allow an iSCSI initiator to log on without supplying any type of CHAP  
authentication.  
None and  
CHAP  
The storage array will allow an iSCSI initiator to log on with or without CHAP  
authentication.  
CHAP  
If CHAP is selected and None is deselected, the storage array will require CHAP  
authentication before allowing access.  
2
3
To configure a CHAP secret, select CHAP and select CHAP Secret.  
Enter the Target CHAP secret (or Generate Random Secret), confirm it in Confirm Target CHAP  
Secret and click OK  
.
Although the storage array allows sizes from 12 to 57 characters, many initiators only support CHAP  
secret sizes up to 16 characters (128-bit).  
NOTE: Once entered, a CHAP secret is not retrievable. Make sure you record the secret in an accessible  
place. If Generate Random Secret is used, copy and past the secret into a text file for future reference since  
the same CHAP secret will be used to authenticate any new host servers you may add to the storage array. If  
you forget this CHAP secret, you must disconnect all existing hosts attached to the storage array and repeat  
the steps in this chapter to re-add them.

.
NOTE: In some cases, an initiator CHAP secret may already be defined in your configuration. If so, use it  
here.  
4
Click Close  
.
NOTE: To remove a CHAP secret, you must delete the host initiator and re-add it.

iscsicli QAddTargetPortal  
<IP_address_of_iSCSI_port_on_storage_array> [CHAP_username]  
[CHAP_password]  
where  
[CHAP_username]is the initiator name  
[CHAP_password]is the target CHAP secret  
If discovery session failover is desired, repeat step 5 for all iSCSI ports on the storage array. Otherwise,  
single-host port configuration is sufficient.

on each controller, ideally from separate host-side NICs. Repeat step 3 through step 7 for each iSCSI port on  
each controller. If using a duplex MD3000i configuration, then LUNs should also be balanced between the  
controllers.  
The Status field on the Targets tab should now display as Connected  
Click OK to close the Microsoft iSCSI initiator.

Start the iSCSI service (if necessary):  
sc start msiscsi  
Log on to the target:  
iscsicli PersistentLoginTarget <Target_Name> <Report_To_PNP>  
<Target_Portal_Address> <TCP_Port_Number_Of_Target_Portal> * * *  
<Login_Flags> * * * * * <Username> <Password> <Authtype> *  
<Mapping_Count>  
where  
<Target_Name>is the target name as displayed in the target list. Use the iscsicli  
ListTargetscommand to display the target list.  
<Report_To_PNP>is T, which exposes the LUN to the operating system as a storage device.  
<Target_Portal_Address>is the IP address of the iSCSI port on the controller being logged in  
to.  
<TCP_Port_Number_Of_Target_Portal>is 3260.  
<Login_Flags>is 0x2to enable multipathing for the target on the initiator. This value allows more  
than one session to be logged in to a target at one time.  
<Username>is the initiator name.  
<Password>is the target CHAP secret.  
<Authtype>is either  
0
for no authentication,  
1
for Target CHAP, or  
2
for Mutual CHAP.  
NOTE: <Username>, <Password> and <Authtype> are optional parameters. They can be replaced with an  
asterisk (*) if CHAP is not used.  
<Mapping_Count>is 0, indicating that no mappings are specified and no further parameters are  
required.  
* * * An asterisk (*) represents the default value of a parameter.  
For example, your logon command might look like this:  
iscsicli PersistentLoginTarget  
iqn.1984-05.com.dell:powervault.6001372000ffe333000000004672edf2

To view active sessions to the target, use the following command:  
iscsicli SessionList  
To support storage array controller failover, the host server must be connected to at least one iSCSI  
port on each controller. Repeat step 3 for each iSCSI port on the storage array that you want to  
establish as a failover target. (The Target_Portal_Addresswill be different for each port you  
connect to).  
PersistentLoginTargetdoes not initiate a login to the target until after the system is rebooted.  
To establish immediate login to the target, substitute LoginTargetfor  
PersistentLoginTarget.  
NOTE: Refer to the Microsoft iSCSI Software Initiator 2.x User’s Guide for more information about the  
commands used in the previous steps. For more information about Windows Server 2008 Server Core, refer to  
the Microsoft Developers Network (MSDN). Both resources are available at www.microsoft.com.  
If you are using a Linux Server  
If you configured CHAP authentication in the previous steps, you must restart iSCSI from the Linux  
command line as shown below. If you did not configure CHAP authentication, you do not need to restart  
iSCSI.  
/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.  
Sample output from the command should look similar to this:

Viewing the status of your iSCSI connections  
In MD Storage Manager, clicking the iSCSI tab and then Configure iSCSI Host Ports will show the  
status of each iSCSI port you attempted to connect and the configuration state of all IP addresses. If  
either displays 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?  
Is CHAP set up correctly on both the host server and the storage array?  
To review optimal network setup and configuration settings, see Guidelines for Configuring Your Network  
for iSCSI.

Step 8: (Optional) Set Up In-Band Management  
Out-of-band management (see Step 1: Discover the Storage Array (Out-of-band management only)) is the  
recommended method for managing the storage array. However, to optionally set up in-band  
management, use the steps shown below.  
The default iSCSI host port IPv4 addresses are shown below for reference:  
Controller 0, Port 0: IP: 192.168.130.101  
Controller 0, Port 1: IP: 192.168.131.101  
Controller 1, Port 0: IP: 192.168.130.102  
Controller 1, Port 1: IP: 192.168.131.102  
NOTE: The management station you are using must be configured for network communication to the same IP  
subnet as the MD3000i host ports.  
NOTE: By default, the MD3000i host ports are not IPv6 enabled. To use IPv6 for in-band management, you  
must first connect either out-of-band, or in-band using the default IPv4 addresses. Once this is done, you can  
enable IPv6 and begin step 1 below using the IPv6 addresses.

Guidelines for Configuring Your Network  
for iSCSI  
This section gives general guidelines for setting up your network environment and IP addresses for  
use with the iSCSI ports on your host server and storage array. Your specific network environment  
may require different or additional steps than shown here, so make sure you consult with your system  
administrator before performing this setup.  
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 storage array. 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.  
NOTE: The server IP addresses must be configured for network communication to the same IP subnet  
as the storage array management and iSCSI ports.  
If using a DHCP server
