Understanding D3-10i Array Management

The D3-10i array is flexible enough to be implemented in a number of ways, from a single-server storage solution up to a multi-server SAN infrastructure. No matter which approach is used, the array requires an Ethernet connection to a server and client that will perform management functions and an Ethernet connection to servers that will access the array’s storage.

Figure 2. Sample D3-10i Infrastructure Design

Even though these roles can be implemented on a single server, this document describes these as distinct server roles as follows:

Management Server – The management server role is performed by a server with the Storage

Manager software installed. This server is attached to the array via an Ethernet connection.

Management Client – The management client role is performed by any Windows workstation or server

that connects to the management server via the Web-based management interface.

Application Server – The application server role is performed by any server that uses the array

storage via an iSCSI connection.

Requirements

The following equipment, tools, and resources are required to complete this installation.

Network Cables – At least two Ethernet cables will be required.

o 1 Ethernet cable is required for connection to the management port. o 1 Ethernet cable is required for each iSCSI port that will be used for connections to application

servers.

IP Addresses – There is one management port and two iSCSI ports on each controller. Each port that

will be used requires a unique IP address. Those IP addresses should be reserved and all associated

network settings should be confirmed before installation. Tools – You will need the installation CD (shipped with unit) and a #1 Phillips-head screwdriver. Rack space – If rack-mounting, 2U of rack space is required for each base unit and an additional 2U of

space is required for each additional disk enclosure. Power Requirements – Two available outlets providing AC 100-240V single phase 50/60Hz for a

NEMA 5-15P plug will be required for each base unit and each disk enclosure. Power and cooling

requirements are listed in the table below.

Table 1. Storage unit power requirements

Page 5

STEP 1: Planning and Preparation

This section describes the planning and preparation steps that need to occur before you install the array.

Preparing For Installation

Before installing the array, the following steps should be performed on the application servers that will be connected to the array:

1. Install any additional gigabit Ethernet NICs on all application servers as needed for iSCSI connectivity.

2. Install and apply the latest driver updates for all application server NICs that will be used for iSCSI connectivity.

3. Ensure that the array and application servers will reside on the same network subnet and all necessary IP addresses have been reserved for each iSCSI port that will be connected to that network.

4. Optional: Install and configure at least one iSCSI Naming Services (iSNS) Server on the same network segment as the array and the application servers that will connect to the array.

5. If a specialized iSCSI HBA will be used instead of a software iSCSI initiator, ensure that all iSCSI adapters and iSCSI switches, if used, are installed and configured on all application servers as specified by the hardware vendor.

Note: Check with your D3-10i sales representative to get the latest information about iSCSI HBAs that have been certified for use with the D3-10i array.

Unpacking the Array

While unpacking instructions are illustrated on the array packaging materials, the following tips should be kept in mind when unpacking the base unit.

To prevent component damage caused by condensation due to rapid temperature and humidity

changes, please allow the base unit to sufficiently acclimate to the ambient room temperature before unpacking.

To prevent injury, the array should be unpacked, lifted out of the packing materials, and moved by at

least two people.

To prevent damage to the base unit, the unit should be held by the bottom of the unit when removed

from the packing material or moved. It is not recommended to lift or carry the unit by holding on to projecting surfaces such as the power supply units or plastic bezel mounts.

Please save all packing materials in case the unit needs to be returned for repairs or shipped to other

locations.

Record the array serial number and model number located on the back of the array or inside the

cabinet door of the array, then visit http://www.necam.com/registration to fill in your self-support registration information in order to receive an additional 30 days of warranty coverage.

Warning: Bezel mounts are fragile and should not be used as handles to lift the base unit or be exposed to any other strong forces.

STEP 2: Array Installation

This section describes the steps necessary to complete the physical installation of the array. These steps should occur before you connect the array to a server.

Hardware Installation

This section describes the steps you need to perform to physically install an array into a rack and prepare for connection to any servers.

Mounting the Array

Before mounting the array in a rack enclosure, please observe the following:

When installing both disk enclosures and base units in the same rack, the disk enclosures should be

mounted above the base unit.

If an optional external battery backup unit (BBU) will be installed in the same rack, at least 1U of space

should be reserved underneath the base unit for the external BBU.

If the array is being installed into a rack containing other equipment, the heaviest rack units should be

mounted as close to the bottom as possible, while lighter units can be placed near the top.

For the purpose of determining the proper positioning in the rack, a fully loaded base unit may weigh in

excess of 68 lbs and a fully configured disk enclosure may weigh in excess of 63 lbs.

The rack mount rail mounting points are illustrated in Figure 5 above and show M5 screw placements for the two center screw holes in the front of each rail. Screws are positioned above and below the inner rail tabs at the rear of each rail as well. The array then slides into the rails from the front and is secured by two screws on each

side of the plastic bezel mount, above and below the front rail mounting screws.

Figure 5. Mounting the Array

Page 10

Installing Disk Drives

To remove drives or trays, simply push in the tab on the drive carrier to unlock the drive latch, pull the latch out to the open position as seen in Figure 6 below, and then slide the drive or tray out of the disk drive bay.

Figure 6. Array Disk Drive Latch Open Position

To install a drive or tray in an empty drive bay, simply slide the drive or tray into the empty bay with the drive latch in the open position until the drive latch catches on the inside edge of the drive bay, then move the latch to the closed position until it locks into place with a click.

While the drive removal and insertion process is simple, there are some general guidelines to keep in mind when installing and removing disk drives from the array.

Note: All array disk drives should be reseated before the initial startup anytime after the array is transported or shipped with the drives installed.

The disk drives in positions 00, 01, and 02 function as a system drive stripe set and must remain

mounted and remain in their original positions for proper array operation.

If disk drives in positions 00, 01, or 02 must be replaced, only remove one drive at any given time. When installing more than one drive while the system is powered on, only install one drive at a time.

Wait until each drive reaches a ready state before installing the next drive.

When replacing failed disk drives, replace each drive with the same drive model. Use dummy trays in any vacant slots to maintain proper unit air flow.

Cable Connections

This section describes the various connection points used for network and storage connectivity.

SAS Cable Connections

The array SAS ports are used to connect the base unit with additional disk enclosures to expand storage capacity. When connecting a disk enclosure to the base unit, use an SAS wide-link cable to connect each DPIN port on the disk enclosure to the DP0 or DP1 port on the base unit. To connect more than one disk enclosure, connect the DP-IN on the next disk enclosure to DP-OUT on a previously connected disk enclosure as shown in Figure 7 below.

The D3-10i can support up to 11 additional disk enclosures. For more information about connecting multiple disk enclosures to an array, Disk Enclosure (DE) and Physical Disk (PD) numbering recommendations, and other considerations, please refer to the documentation contained in the CD shipped with your base unit.

Array Connection Configurations

The D3-10i SAN Storage array can be used in a number of configurations, ranging from a Direct Attached Storage (DAS) configuration to being part of a SAN configuration with the array attached to an Ethernet switch or specialized iSCSI switch.

Additionally, the array can be used in a LUN masking, multipathing, or zoning configuration. While zoning is configured on specialized iSCSI switches and not covered here*, LUN masking and multipathing are dependent on software installed in the array and application server.

LUN Masking – This is the simplest method for configuring an array to connect with multiple

application servers through an Ethernet switch; it’s managed on the array through the use of Access Control in the Storage Manager software on the management server. While it allows multiple application servers to access array resources, it does not offer any fault tolerance unless used with multipathing.

Multipathing – This configuration requires use of NEC’s PathManager software and some additional

configuration, but offers redundant connection paths, support for clustered servers, and other traffic

management features that aren’t available when using the array in a LUN Masking configuration by

itself. The installation and configuration of PathManager is covered in the Appendix of this guide.*

*Note: For more information about zoning configurations, please refer to the manufacturer’s documentation for

your specific model iSCSI or iSCSI/FC switch.

*Note: For information about how to configure multipathing using Microsoft’s iSCSI software initiator instead of NEC’s PathManager, refer to the Microsoft documentation for the software initiator.

iSCSI Connections

As described in the previous section, there are a number of ways in which you can connect the array to an application server or multiple application servers. Generally, though, there are some common basic guidelines and suggestions that should be followed when connecting the array to an application server via iSCSI.

The array uses Cat5e or better Ethernet cables, purchased separately. The array should be connected to application servers via a gigabit Ethernet connection. There should not be any routers or firewalls between the array and application servers.

Maintenance Port

iSCSI Port 0

iSCSI Port 1

Figure 8. Controller iSCSI Ports

As Figure 8 above shows, each array controller has two iSCSI Host Ports built in and can support a maximum of four iSCSI ports utilizing two controller modules in an array. iSCSI ports are numbered from right to left starting at port 0 on the right and port 1 on the left.

Management Connections

The following guidelines should be followed when connecting an array to the network.

The array must be connected to a management server where the Storage Manager software will be

installed to configure the array.

Use the management port on Controller 0 (the controller on the right when viewed from the back of the

unit) if only one Ethernet connection will be used for the array.

Each management port (one on controller 0 and one on controller 1) should have its own IP address

reserved on any DHCP servers. The IP address for each controller is configured manually on the array during the initialization process outlined in the Array Initialization and Configuration section of this guide.

The array, Management Server, and management client must be connected to the network before you

use the initialization wizard in Storage Manager to configure an array’s initial settings.

The Management ports on both controllers should be connected to a network switch to provide the

management server with a redundant connection to the array. However, the array can be managed by connecting just one controller to the network or directly to the management server with a crossover cable if necessary.

Figure 9. Array Controller Management Port

Page 13

Power Button

Power Cable Connections

The base unit is shipped in “Auto Power On” mode, so the base unit will turn on when the power cables are

plugged into the unit and an outlet. Therefore, the following steps should be performed before connecting any power cables to the array:

Ensure that all disk drives are properly seated. Ensure that all Ethernet cables have been properly connected. Ensure that any SAS cable connections to additional disk enclosures are properly connected. Plug in the power cables for any additional disk enclosures attached to the base unit before connecting

the base unit power cables.

To plug an AC power cable into a base unit or disk enclosure:

1. Spread the AC cable clamp.

2. Connect the power cable to the unit.

3. Loosely lock the clamp around the power cord, but do not tighten.

4. Move the clamp in the direction indicated in Figure 10 below until the clamp is fixed securely to the base of the AC cable plug as shown, and then tighten.

Figure 10. Using Power Cable Management Straps

Power-On/Power-Off Procedures

The array power buttons are located on each controller module at the back of the base unit, as shown in Figure 11 below.

Figure 11. Power Button Location on Array Controller

Power-On Procedure When Auto Power On Mode Is Not Enabled

If the array has been shut down using the power button or if Auto Power On mode is not enabled, the array can be turned on by depressing the power button and holding it in for approximately one second. If there are two controllers on the base unit, only one power button needs to be depressed to turn an array on or off.

When the array is first powered on, it will perform a self-test, which is indicated by a flashing Service LED. After the array has successfully finished the self-test process, the Power LED should remain lit and the Service LED should turn off. Application servers can be connected to the array after the self-test is completed.

*Note: If the Power LED does not remain lit or if the Service LED does not turn off after the self-test, a controller

fault may have occurred. For information about identifying and troubleshooting fault conditions, please refer to the D3-10i Disk Array Unit User Guide available on the Storage Manager CD or contact NEC technical support.

Page 14

Power-Off Procedure

To prevent any data loss or corruption, the following process should be followed when an array is to be shut down.

1. Turn off or disconnect application servers using the prescribed shut-down process for that server’s applications and operating system.

2. Turn off the array by depressing the power button located on the array controller at the rear of the base unit.

3. Turn off the external BBU if used.

4. If the array needs to remain powered off for more than a few hours, partially eject both controllers from the base unit at the same time and then reseat them, to prevent the internal battery backup from draining.

Page 15

STEP 3: Software Installation

The D3-10i SAN Storage array comes standard with Storage Manager software that is required to use basic array features. To extend an array’s feature sets, additional software can be installed depending on which features would be best suited for any given environment.

This guide covers the installation and configuration tasks that would be necessary to enable the common functionality required in an average enterprise environment using Storage Manager software. For more information about other software suites and the features they enable for the D-Series array, please refer to the relevant documentation on the CD included with the base unit.

Management Server Installation

The Storage Manager setup CD contains installation software for systems performing the management server, application server, and management client roles.

The Storage Manager software generates a large number of files and constantly updates files during normal operation. Therefore, it is recommended that the installation path for the Storage Manager software be excluded from any real-time virus scanning routine. Also, while a single management server can monitor several arrays simultaneously, an array should not be managed by more than one management server.

Installing Storage Manager

The following steps take place on the system designated as the management server.

1. Log on to the management server using an account with administrator privileges.

2. Insert the Storage Manager CD.

3. Start the Storage Manager setup. If the Storage Manager setup does not start automatically after inserting the CD, manually run <CD Drive>:\StorageManager\Install\Windows\ISMSETUP.EXE

4. At the Select Setup Method window, select Setup the management server from the Quick Install section, and then click Next.

*Note: Windows Server 2008 in UAC mode may

require an additional step before this step to grant permission to run the setup.

Page 16

5. At the License Agreement window, select Accept, and then click Next.

6. At the Choose Destination Location window, either leave the default installation path in place or click Browse to select a new installation path, and then click Next.

7. At this point, the Storage Manager installation will attempt to install Java. Click Accept to begin installing Java.

Note: Storage Manager requires the use of a

specific version of Java that comes with the installation software. Ensure that Java is installed during this step even if another version of Java has already been installed on this server, to avoid any compatibility issues.

Page 17

8. After the Java installation process has completed, click Finish to continue with the Storage Manager installation process.

9. Allow the setup process to run until setup prompts you to create a System Administrator account and password. This account will have full access to all configuration tasks and user management roles within Storage Manager. Select a User Name and Password, and then click OK.

10. At this point, you can create more user accounts and grant each account the appropriate access rights to Storage Manager settings as follows:

Standard (L1) – Authorized for disk

monitoring, state display, and other readonly tasks.

Operator (L2) – Authorized for changing

optimization settings and starting snapshot or replication tasks.

Administrator (L3) – Authorized for any

management tasks.

To add users, click Add, create the username and password, select the access level, and then click OK. After all users have been created, click Next to continue.

Page 18

11. At this point, the installation process has been completed and a system restart will be required before starting Storage Manager for the first time. Either click Finish to close the Storage Manager Setup and restart the server, or if you do not want to restart the server at this time, select Restart later, and then click Finish.

12. After the management server has restarted, the Setup Complete window will appear. Clicking Finish will launch a Web browser window that will prompt for a login and then launch the initialization wizard for the array.

Clicking Cancel will still finish the installation but will not open a browser window and initialize the array.

Application Server Installation

After installing software on the management server, the application servers need to be prepared to connect to the array by installing an auto-discovery host agent on the application servers.

The auto-discovery host agent allows you to perform an auto-discovery of hosts during the array initialization process when binding logical drives. This host agent can either be installed as part of iSM Volume List Command or Control Command.

The iSM Volume List installation provides basic host server functionality and the Control Command installation provides advanced features that are necessary when using the advanced software functions of the array.

The following steps outline the process to install the Control Command host agent and configure the application servers to connect with the array through an iSCSI connection with a software iSCSI initiator. For information about how to install iSM Volume List, please refer to the NEC Storage Manager Manuals section on the Storage Manager CD.

Page 19

Control Command Installation

This section describes the installation process for the Control Command software from the Storage Manager installation CD.

1. Log on to the application server with an account that has administrative privileges.

2. Insert the Storage Manager setup CD and run ISMSETUP.EXE from the Autorun prompt or from the <CD Drive>:\ControlCommand\Install\Windows\ directory.

3. From the ControlCommand Setup Welcome window, click Next.

4. From the License Agreement window, select Yes to continue.

5. Review the information for the ControlCommand setup and click Next to continue.

Page 20

6. From the Choose Destination Location window, either leave the default installation path in place or choose a new destination directory by clicking Browse and then selecting the appropriate path. When finished, click Next to continue.

7. At this point, choose a program folder for the ControlCommand program icons, and then click Next to continue.

8. Allow the installation process to continue, and after the installation has finished, the Installation Complete window will appear.

Click Finish to close the wizard and complete the installation process.

Page 21

9. At this point, the server will need to be restarted for the installation to be completed.

Either click Finish to allow the server to restart automatically, or check the box next to Restart later to restart the server manually at a more convenient time.

Page 22

Preparing the Software iSCSI Initiator in a Windows Environment

If you are not using a hardware-based iSCSI initiator then you will need to install and configure a software iSCSI initiator so that the application server can connect with and be configured for use with the D3-10i array.

Microsoft Windows Server 2008 servers already have a built-in iSCSI initiator that only needs to be activated to accomplish this step. However, a software iSCSI initiator must be downloaded and installed for any Microsoft Windows Server 2003 (or earlier) server that will be connected to the array prior to initializing the array.

Installing iSCSI Initiator on Windows Server 2008

As noted above, Microsoft Windows Server 2008 and later already have iSCSI capabilities. Even though a software iSCSI initiator doesn’t need to be downloaded and installed, the initiator still needs to be started in order to operate.

1. Log on to the server with an account that has administrative privileges.

2. Launch the iSCSI service by clicking Start, then Administrative Tools, then iSCSI Initiator.

3. When the iSCSI initiator service first starts, it will inform you that the service is currently not running. Click Yes to configure the service to start automatically at each startup.

4. After configuring the iSCSI service to start automatically, you will also need to allow the service to communicate past the Windows Firewall.

Click Yes to enable Windows Firewall to allow Microsoft iSCSI service to communicate with the network.

At this point, the Microsoft iSCSI initiator service has been installed and is ready for use.

Installing iSCSI Initiators on Windows Server 2003

In versions of Windows Server prior to Windows Server 2008, an iSCSI initiator needs to be downloaded and installed on each application server that will connect to the array via iSCSI. To download Microsoft’s iSCSI initiator, visit http://www.microsoft.com/downloads.

Ensure that a copy of the latest version of the Microsoft iSCSI initiator is copied to each application server, and then perform the following steps on each server to install the initiator.

1. Log on to the application server with an account that has administrative privileges.

2. Start the Microsoft iSCSI Initiator installation package from the location where it was copied onto the server.

Page 23

3. Follow the instructions on the Microsoft iSCSI Initiator welcome screen, and then click Next to continue.

4. Select the Initiator Service and the Software Initiator. Microsoft MPIO Multipathing Support for iSCSI should not be used if PathManager will be installed.

Once all needed options have been selected, click Next to continue.

5. At the License Agreement window, select I Agree, and then click Next to continue.

Page 24

6. After the installation process has completed, click Finish to close the installation wizard on the application server.

7. Click Start and iSCSI Initiator from the Start Menu to bring up the iSCSI Initiator properties menu.

8. From the General tab of the iSCSI Initiator Properties menu, you can change the initiator name, configure the CHAP authentication settings, and set up IPsec tunneling mode. (IPsec tunneling is not supported by the NEC D310i array)

To configure CHAP authentication settings, click the Secret button.

9. Type in the desired CHAP secret passphrase in the CHAP secret field, and then click OK to save.

Page 25

10. To configure the discovery settings, click the Discovery tab, and then click Add Portal.

11. In the Add Target Portal window, enter the IP address of the iSCSI array port that this application server will connect with, and then click OK to save.

Page 26

12. After returning to the iSCSI Initiator Properties window, click ADD under the iSNS servers window to configure any iSNS servers that will be used on the network.

Preparing the Software iSCSI Initiator in a VMware ESX Environment

VMware ESX comes with a built-in iSCSI initiator, so no additional download and installation process is required. However, only the VMware host can access iSCSI arrays, not guest operating systems.

To activate the iSCSI initiator for use by VMware, there are some configuration steps that should be performed prior to array initialization in order to be able to assign logical drives to the VMware host during the array initialization process.

Creating a VMkernel Port for iSCSI

The first step in configuring the iSCSI initiator in VMware ESX is to create a VMKernel network configuration for iSCSI communications.

1. Log on to the VI Client and select the application host server from the inventory.

2. Click the Configuration tab, and then click Networking.

3. In the Networking window, click Add Network.

4. In the Add Network Wizard Connection Type window, select the VMkernel radio button, and then click Next.

5. At the Network Access window, select the network adapter(s) that the VMkernel vSwitch will use, and then click Next to continue.

Note: Ensure that the adapters selected for iSCSI

use are at least 1Gb Full or better.

Page 29

6. In the Connection Settings window, you can select a network label and optional VLAN ID for the port group in addition to configuring the IP settings for the new VMKernel connection.

After configuring all necessary settings, click Next to continue.

7. In the Summary window, review the settings, and then click Finish to finalize the new network configuration.

Configuring a Service Console Connection

This step is only necessary for VMware ESX Server Version 3. For other versions of ESX Server, skip to Enabling the iSCSI Initiator for VMware.

1. Log on to the VI Client and select the application host server from the inventory.

2. Click the Configuration tab, and then click Networking.

3. On the right side of the window, click Properties for the VMkernel vSwitch you just created for iSCSI.

Page 30

4. In the Ports tab, click Add to bring up the Add Network Wizard.

5. In the Add Network Wizard Connection Type window, select Service Console, and then click Next to continue.

6. In the Service Console window, type a name for the connection in the Network Label field and configure the IP address settings for the connection. You can also configure an optional VLAN ID if necessary.

When all needed settings have been configured, click Next to continue.

7. In the Summary window, review the configuration settings for the service console connection, and then click Finish to save.

To enable the software iSCSI initiator, click the General tab and then click the Configure button.

4. In the Software Initiator General Properties window, select Enabled and ensure that a properly formatted iSCSI Name is entered into the iSCSI Name field. Then click OK to enable the iSCSI initiator.

Page 32

5. If you are planning to use CHAP authentication, click the CHAP Authentication tab after enabling the iSCSI initiator, and then click Configure.

6. In the CHAP Authentication window, select the Use the following CHAP credentials radio button and then enter the appropriate CHAP name and CHAP secret that will be used to connect the VMware host server to the iSCSI array. After the appropriate settings have been configured, click OK to save and continue.

7. Prior to starting the array initialization process, it may also be necessary to configure a static discovery entry for the disk array so that the VMware host server can find the array during the configuration process.

To configure a static discovery setting, click the Static Discovery tab, and then click Add.

Page 33

8. In the Add Static Targets Server window, enter the IP Address of the disk array port that the VMware ESX host server will connect to, set the appropriate port setting (default is recommended), and assign an iSCSI Target Name for this static discovery entry.

After the configuration settings have been entered, click OK to save, and then exit the iSCSI Initiator Properties window by clicking Close.

Storage Manager Client Installation

The Storage Manager client component is a Web browser-based GUI that can be used on the management server or any other system that has network access to the management server. The Storage Manager client is only supported on Microsoft Internet Explorer® 6 and above, and it requires some configuration before use, as shown below.

Storage Manager Client Installation and Startup

Perform the following steps on the system that will be used to configure Internet Explorer for the Storage Manager client:

1. Open the Start Menu, select Control Panel, Internet Options, and then select the Security Tab.

2. Highlight Trusted sites, and then click the Sites button.

3. In the Trusted Sites window, type the URL or IP Address of the management server, and then click the Add button.

Note: If the management client is running on the

same machine as the storage manager server, type the loopback address as shown on the right, and then click Add.

4. Uncheck the Require server verification (https:) for all sites in this zone checkbox, and

then click Close to continue, but do not close the original Internet Options window.

Page 35

5. From the Security Settings window under the Security tab, highlight Trusted sites, and then click Custom level.

6. In the Security Settings window, scroll down to the Run ActiveX controls and plug-ins entry and select Enable if it is not already selected, and then click OK.

7. Start Internet Explorer and navigate to the

management server’s network address and port

(default port 8070). If the server has an associated DNS entry, navigate to that address in the browser window. If the server is only identified by an IP address, navigate to that address and follow the prompts to install the client software.

At this point, the software installation process has been completed and you can manage the array with the iSM client by navigating to the management server address within the Web browser.

Everything should be ready for the array to be initialized and configured at this point. However, if the Storage Manager fails to launch and prompt for a user name and password, go back through the configuration steps to ensure that everything is correct.

Page 36

STEP 4: Array Initialization and Configuration

This section describes the process used to initialize and configure the array for use in a Microsoft Windows environment.

Array Initialization

This section will describe the step-by-step process of using the Management Client Initialization Wizard to initialize the array. Array initialization is only required for newly deployed arrays. Previously deployed arrays moved to a new network or location should be reconfigured as if an array initialization process has already been performed, by configuring logical disks and pools as described on page 49 of this guide.

If the array is being used with an iSCSI switch, the switch should be configured before starting this step, so that the array can connect with any application servers for the host information gathering process. Ensure that all application servers are operational and connected to the switch and/or array before beginning the initialization process.

1. Start Internet Explorer and navigate to the

management server’s network address and port

(default port 8070). If the server has an associated DNS entry, navigate to that address in the browser window. If the server is only identified by an IP address, navigate to that address.

Note: If the client browser cannot connect to the

Storage Manager host over the network, make sure that the management server is attached to the network, the Storage Manager service is running, and that any intervening network firewalls or client firewalls have a rule that permits UDP port 2730 traffic to pass through.

2. Log on to the Storage Manager client with a previously created user name that has administrative privileges.

Page 37

3. In the Storage Manager Client browser window, select File from the top toolbar, then click Initialization Wizard from the drop-down menu.

4. At the Initialization Wizard start screen, ensure that the prerequisite steps have been performed as listed, and then click Next when everything is ready for initialization.

5. At the Disk Array Selection window, select the array to be initialized, and then click Next.

Note: To be initialized, an array must be in the

Not Initialized state. Arrays in a Suspended or Finished state have already been initialized and should be configured by using the steps outlined in the Configuring Logical Disks and Pools section on page 35.

Note: The wizard will only initialize one array at a time. If multiple arrays are selected, the wizard will initialize the first array and then restart the initialization process for subsequent arrays until all selected arrays have been initialized.

Page 38

6. After selecting the array, a confirmation window will appear. Confirm that the correct array was selected and click Yes to continue. Otherwise, click No to go back and then select the correct array.

7. The Disk Array Connection State Confirmation window displays an example of how an array should be cabled. Verify that the array is cabled correctly and click Next, or click Cancel if there is a problem with your array’s connections.

Note: This screen shows a fully configured array

only. It does not show your specific configuration.

8. After completing an initialization, an initialization file can be generated and used to configure other arrays or reconfigure the existing array. This step allows you to choose between using the initialization wizard or a previously generated installation file from another array to configure this array.

During an initial setup of an array, choose Use

this wizard. Otherwise, select Use an initialization file and type the location of that file

in the field below. After the appropriate option has been selected,

click Next to continue.

9. At the Host Information Collection window, you can select Automatic collection as long as the application servers to be configured have not been configured for use with an array previously, and as long as the Volume List Command or ControlCommand software has been installed on the desired application server(s).

If these conditions have not been met, the host information will have to be gathered and typed in manually during the initialization process.

After selecting or clearing the Automatic collection field as appropriate, click Next to continue.

Page 39

10. If automatic collection was selected, an initialization warning will appear to notify you that the operating system on the application server that the array automatically connects to can affect how the array is configured during the initialization process. If the array is being installed in an environment other than Windows, please refer to the array user manual before continuing. Otherwise, click OK to continue.

11. At the Set Network Parameters window, type in the network addressing information for each controller that will be used on the array. The IP Address for each controller should be unique and should be reserved in any DHCP server before configuring. After typing in the network information for the array, click Next to continue.

12. After you type in the network information for the array, a confirmation window will appear. Verify that the information entered was correct, and then click Set to continue.

If the information is not correct, click Back and type the information again before continuing.

13. At the Set Host Connection Port Parameters window, review the port parameters for the array. If any parameters need to be changed, highlight the port to be changed and click Edit on the right of the port list. If an iSCSI Naming Service server is to be used, configure the iSNS Server settings by clicking the Set iSNS Server button at the left side of the window. After all ports are configured correctly, click Next to continue.

Page 40

14. If any ports needed to be edited in the previous step, this port editing window will appear. Here you can modify the host port MTU, IP Address, Subnet Mask, and Gateway address.

When you are finished editing port settings, click OK to return to the previous Set Host Connection Port Parameters window.

15. If Set iSNS Server is selected in Step 13, the Set iSNS Server settings window will appear. To register an iSNS Server, click Add and enter the IP Address and Port settings for each iSNS Server the array can connect to. Up to four iSNS Servers can be registered on each array.

When all iSNS Servers have been added, click OK to continue.

16. After you set the host connection port parameters, a confirmation window will appear. Review the port settings and click Set to continue if they are correct. Otherwise, click Back to return to the previous step and modify the port settings as needed.

Page 41

17. At the Enter License Keys window, type in the Base Product License key from the NEC Storage software license code provided on the Program Product License Sheet that was shipped with the array. Click Enter after the code has been typed in the License Key field. When the code has been typed, click Next to continue.

Note: At this time, do not enter in other license

codes. More specifically, if you enter the Access Control license key, you will need to set up Access Control or servers will not be able access the Logical Disks. Setting up Access Control is not included in the Quick Start Guide.

18. In the Select Logical Disk Binding Method window, you can choose between binding logical disks within the initialization wizard and creating logical disks after completing the initialization process.

Choosing the Bind logical disks using the wizard option allows you to use the wizard to create and bind logical disks to application servers using RAID1, RAID6 (4+PQ), or RAID6 (8+PQ) while performing the array initialization.

If another type of logical disk is required, this step can be skipped by choosing the Bind logical disks later option.

After choosing the appropriate option, click Next to continue.

19. If the Bind logical disks using the wizard option was selected in the previous step, the Set the LD Set window will be shown. Here you can specify which operating system platform the logical disk set will be used with, and name the logical disk set.

From this window, you can also configure iSCSI CHAP Authentication settings and set access restrictions on a per-portal basis by clicking either the Authentication Settings or Access Restriction per Portal button.

After you have finished modifying the settings for the logical disk set, click Next to continue.

Page 42

20. After setting the logical disk name and platform type, you can configure the initiator node that the logical disk will be bound to. Select the initiator from the Assignable Initiators section, and then click Add to assign an iSCSI Initiator to the specified Destination LD Set or select the Type In/Edit button to manually enter an Initiator’s information.

Once an initiator has been selected for the destination logical disk set, click Next to continue.

21. The Select LD Binding Parameters window allows you to create and bind logical disks to application servers.

The following options are available when binding logical disks from the wizard:

Bind/Select – This takes you to the Bind

Pool and Bind Select window which allows you to configure and select a pool to be bound to logical disks.

LD Capacity – Set the capacity of the logical

disks.

Number of LDs – Set the number of logical

disks to create.

LD Name Prefix – Add a prefix name to the

logical disk.

Quick Format – Perform a quick format of

any logical disks created.

GPT Disk Type – Enable GPT type if a

volume is larger than 2 TB.

Create Hot Spare – Assign a physical disk

as a hot spare drive for the logical disk. (Recommended)

When all settings are correct, click Next to continue.

Note: If you change the Number of LDs, the LD Capacity needs to be manually changed.

Page 43

22. If you click Bind/Select in Step 21, the Bind/Select window will allow you to create a pool and assign physical drives to that pool in a specified RAID configuration.

When the needed logical drives and pools have been configured, click OK to continue.

23. After setting the logical disk binding parameters, a confirmation window will appear. Review the settings and license information listed, and if everything is correct, click Set. Otherwise, click Back and configure the proper settings before continuing.

24. After configuring logical disks and confirming that all settings are correct, the array will begin setting the configuration and building any logical disks that may have been configured. When the initialization process is complete, an Initialization Complete window will appear.

At this point, click Finish to complete the initialization, and then confirm that all configured logical drives and application servers are connected through the Storage Manager client.

Page 44

Configuring iSCSI Connections

After the array has been initialized and all needed logical drives have been configured, the iSCSI initiators on the application servers will need to be configured in order to mount any logical drives that are configured for the application server. Once configured, the logical drives created during the initialization process can be mounted by the application server.

If logical drives were not created during the initialization process or additional logical drives and pools are needed, then refer to the Configuring Logical Disks and Pools section that appears later in this document before continuing with these steps.

Configuring the iSCSI Initiator in Windows

To configure the iSCSI initiator on a Windows server, ensure that the port IP address that the application server will connect with has been recorded and that the CHAP secret, if used, has also been recorded.

1. Launch the iSCSI Initiator properties menu by clicking Start and then iSCSI Initiator.

2. In the iSCSI Initiator Properties window, select the Targets tab. In the Targets window, select the appropriate array, and then click Log On.

3. At the Log On to Target window, select the

Appendix: Configuring Multipathing

NEC Storage PathManager enables multi-path connection capabilities with the array that allow the configuration of path failover for redundancy, load balancing between paths for performance improvements, and clustering support.

PathManager consists of the following components:

PathManager Driver – A driver that manages and controls basic PathManager functionality, such as

redundant paths and load balancing.

Operation Command (spscmd) – A command-line utility that allows you to check the status of paths

and configure PathManager settings.

Path Patrol Service – A service that automatically monitors path status and collects information from

the PathManager driver for log collection activities.

Log Service – A service that writes events related to PathManager activity to the Event Log.

PathManager can be installed in a single-server direct connection configuration, a multi-server loop or fabric configuration, and a clustered server configuration to eliminate the need for failover to be configured on the cluster nodes.

Installing PathManager

This section describes the installation process for PathManager on a Microsoft Windows Server 2003 or Microsoft Windows Server 2008 system. For information about installing PathManager in other environments, please refer to the PathManager documentation contained on the StorageManager CD.

1. If there is already data on the logical disk in use, disconnect the application server from the storage array before continuing.

Note: It is important that the server not be connected to the array until the PathManager setup has been

completed, to prevent damage to the file system. Note: When installing ExpressCluster (ClusterPro) with PathManager, install PathManager first and

then install ExpressCluster MSFC.

2. Start the installation process from the Storage Manager CD through the Web-based browser interface available by running Index.HTML from the root of the CD drive. Follow the links from there to the NEC Storage PathManager installation appropriate for your operating system.
