Introduction

Thank you for your purchase of the NEC D3-10/D4-30 SAN Storage array. This document provides instructions that are designed to help experienced IT professionals to install and configure the array as quickly as possible.

Since this document is a Quick Start Guide, the following assumptions have been made:

• Readers have experience with network and storage terminology and configurations.

• Readers have experience with Microsoft Windows™ administration.

• The array will be deployed in a Microsoft Windows environment.

• Expansion options, like an external battery backup unit (BBU), are not currently being installed with this

array.

Throughout this document, the term “base unit” refers to the enclosure containing the array controller modules, and the term “array” refers to the base unit and any attached disk enclosures collectively. To read about information not covered in this documentation, please refer to the additional documentation contained on the CD media that comes with the array.

To review documentation on the Storage Manager CD when Autorun is disabled, navigate to the root directory of the CD drive and launch Index.HTML. From the browser window, you can navigate to all the documentation and installation software available for use with the array.

Understanding D-Series Array Management

The D-Series 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 a Fibre Channel connection to servers that will access the array’s storage.

Management Server Management Clients

Application Servers

LAN

D-Series Array

Fibre Channel

Figure 2. Sample D-Series 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 a Fibre Channel connection.

Requirements

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

• Network Cables – At least one Ethernet cable will be required to connect the array to an Ethernet switch or hub that is used by the server designated to manage the array. However, it is highly recommended to use two Ethernet cables for redundancy. If the management server will be connected directly to the array, at least one crossover Ethernet cable will be required instead.

• IP Addresses – There is a management port on each controller. Each management port to be used will require a unique IP address. Those IP addresses should be re served and all associated network settings should be confirmed before installation.

• Tools – You will need the installation CD (shipped with unit) and a #1 Phillips 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.

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. All requisite hardware and drivers should be installed on the application se rvers.

2. Record the WWPN (World Wide Port Name) of the Fibre Channel controller host bus adapters (HBA). Note: This step is only required if application servers will be connected to the array using LUN masking

or soft zoning. While the WWPN is normally obtained automatically during software installation, it is still recommended that the WWPN be recorded in case of an HBA fault or in case the software cannot determine the WWPN and requires manual input instead.

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.

STEP 2: Array Installation

This section describes the steps nece ssary 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.

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

forces.

stron

The rack mount rail mounting points are illustrated in Figure 5 above and show M5 screw placeme nts 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.

NEC D3/D4 Quick Start Guide 7

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, storage, and Fibre Channel 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 encl osure as shown in Figure 7 below.

The D3/D4 can support up to 11 additional disk enclosures. For more information on connecti ng multiple disk enclosures to an array, Disk Enclosure (DE) and Physical Disk (PD) numbering recommenda t ions, and other considerations, please refer to the documentation contained in the CD shipped with your base unit.

Array Connection Configurations

The D3/D4 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 a Fibre Channel (FC) switch fabric.

• A server can be connected to the array directly via FC Point-to-Point (FC-P2P) or FC Arbitrated Loop (FC-AL).

• Servers can be connected to the array through a switch in an FC switched fabric (FC-SW) configuration.

• Either 1 or 2 ports per controller can be connected to hosts. With D3 and HPE option, from 4 to 6 ports can be attached to hosts per controller.

Additionally, the array can be used in a LUN masking, multipathing, or zoning switch fabric configuration. While zoning is configured on an FC switch 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 a switch fabric and is 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 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 on zoning configurations, please refer to the manufacturer’s documentation for your specific model FC switch.

Fibre Channel 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 a server, FC hub, or FC switch.

• The array uses LC-LC-type FC cables that must be purchased separately.

NEC D3/D4 Quick Start Guide 9

Page 12

• When handling FC cables, do not touch the polished cable terminations and do not use excessive force

when connecting the cables to avoid damaging the cables or FC ports.

• Ensure that the cable paths do not expose fibre cables to excessive bending or pinching, as some fibre cables may be susceptible to damage when bending.

• Do not dispose of the FC port covers on the array controllers, as these keep dust and other contaminates off of the FC port lens to ensure proper FC performance. Whenever cables are not connected to a port, the port should have a port cover in place.

FC Port 2 FC Port

FC Port 1

Figure 8. Controller FC Ports

FC Port

As Figure 8 above shows, each array controller has two FC Host Ports (FC ports) built in and has the capacity for additional FC ports with optional Host Port Expansion (HPE) modules. FC ports are numbered from right to left starting at FC port 0 at the bottom right to FC port 5 at the top left where an expansion module has been installed.

Ethernet Cable 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 a ddress 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 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.

NEC D3/D4 Quick Start Guide 10

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 followed before connecting any power cables to the array:

• Ensure that all disk drives are properly seated.

• Ensure that all Ethernet and Fibre Channel 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.

Power Button

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 as 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.

NEC D3/D4 Quick Start Guide 11

Page 14

*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/D4 Disk Array Unit User Guide available on the Storage Manager CD or contact NEC techni cal support.

Power-Off Procedure

To prevent any data loss or corruption, the following process should be followed when an array is to be shu t 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 until the Ready LED starts blinks at a faster rate then release the power button. The power button is 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.

NEC D3/D4 Quick Start Guide 12

Page 15

STEP 3: Software Installation

The D3/D4 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 com mon 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 perfo rming the management server, application server, and management client roles.

The Storage Manager software generates a large number of files and constantly updates files during norm al 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 ma nagement server.

1. Log in 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.

NEC D3/D4 Quick Start Guide 13

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.

NEC D3/D4 Quick Start Guide 14

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.

NEC D3/D4 Quick Start Guide 15

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 Command Control.

The iSM Volume List installation (shown below) provides basic host server functionality. The Command Control installation provides advanced features that are necessary when using the advanced software functions of the array. For information about how to install Command Control, please refer to the NEC Storage Manager Manuals section on the Storage Manager CD.

The following steps outline the process to install the iSM volume list host agent and configure the application servers to connect with the array through a Fibre Channel connection.

NEC D3/D4 Quick Start Guide 16

Page 19

iSM Volume List Command Installation

This section describes the installation process for the iSM Volume List command from the Storage Manager installation CD.

1. Log in 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>:\StorageManager\Install\Windows\ directory.

3. From the Select Setup Method window, select Setup an application server under Quick Install, and then click Next.

4. From the License Agreement window, select

Accept, and then click Next.

NEC D3/D4 Quick Start Guide 17

Page 20

5. 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.

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

Host Information Collection

Normally, host information is gathered automatically during the array initialization and configuration process, but if an application server is not connected during the initial array configuration process or if the automatic host information collection process does not work, the following procedure can be performed to generate a host information file.

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

2. Open a command prompt on the application server.

3. At the command prompt, type the following command: iSMcc_hostinfo –export \ServerName Replace “ServerName” with the Windows computer name of the application server where the comm and

is being run as shown below.

NEC D3/D4 Quick Start Guide 18

Page 21

4. After the process has completed, ensure that the “Host information was exported successfully” message has appeared.

5. After the process is finished, a “Command has completed successfully” message will be displayed and the host information file will be created in the root directory of the drive where the command was launched. You can then copy the generated file, named after the server name entered in Step 3, from the application server to the management server via a network share or portable storage media for use during the logical disk binding process.

NEC D3/D4 Quick Start Guide 19

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 Internet Explorer 6 and above and 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.

NEC D3/D4 Quick Start Guide 20

Page 23

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.

NEC D3/D4 Quick Start Guide 21

STEP 4: Array Initialization and Configuration

This section describes the process used to initialize and configure the array for use in a Microsoft Win dows 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 35 of this guide.

If the array is being used with an FC 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 in to the Storage Manager client with a previously created user name that has administrative privileges.

NEC D3/D4 Quick Start Guide 22

Page 26

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.

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.

NEC D3/D4 Quick Start Guide 24

Page 27

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.

10. If automatic collection was selected, an initialization warning will appear to notify you that the operating system on the application server 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.

Page 31

17. 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.

18. If the Bind logical disks using the wizard option was selected in the previous step, the Select LD Binding Parameters window will appear and allow you to create and bind logical disks to application servers.

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

• RAID Type/PD Type – Choose the

RAID type and the physical disk type if both SAS and SATA disks are in the array.

• LD Capacity – Set the capacity of

the logical disks.

• Number of LDs – Set the number of logical disks to create.

• Select Hosts – Assign up to two application servers to access the logical disks or create the logical

disk without assigning it to any hosts.

• LD Set Name – Assign a name to the logical disk set.

• 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 – If a volume is larger than 2 TB, GPT type needs to be enabled.

• Create Hot Spare – Assign a physical disk as a hot spare drive for the logical disk.

(Recommended)

• Refresh button – The refresh button can be used if no hosts are selectable when creating a logical

disk. This button will bring up a window that prompts for an update with information from the Storage Manager server or to update with information from a file.

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.

Confirming Connections

After initializing the array, the array and hosts can be configured from the Storage Manager client. The first tasks that should be performed after initializing the array, however, are to confirm that the array and application servers are communicating correctly. Then you can configure any logical disk mappings that were not completed during the initialization process.

Confirming Array Connections

1. Open Internet Explorer and navigate to the management server’s network address and port number (default port

8070).

2. Log in to the Storage Manager client with an account that has administrative privileges.

3. Expand the menu under the array that needs to be confirmed, and then select Connected Host.

4. Right-click the application server you want to check, and then click Properties.

NEC D3/D4 Quick Start Guide 31

Page 36

5. After any necessary disk initialization process has been completed, the new logical drives should be visible from within the Disk Management window. The logical disks are now ready to be configured for use on the application server and formatted as needed.

If the logical drives do not appear on the application server, check all physical connections and restart the application server.

If they still do not appear or were not created during the array initialization process, attempt to create and bind logical drives through the Storage Manager client as shown in the Configuring Logical Disks and Pools section below.

NEC D3/D4 Quick Start Guide 34

Page 37

Configuring Logical Disks and Pools

In case the step to bind logical disks was skipped during the array initialization, if the logical disks that were created are not visible from an application server, or if a new application server is being added to the array, logical disks or pools may need to be created and bound to that specific server or cluster through the Configuration Settings wizards available in the Storage Manager client.

Creating and Configuring Pools

The first step in creating a set of logical drives is to create a pool for those logical drives to be assigned to. The following process illustrates how to configure an individual pool. For more information on the pool configuration process, please refer to the documentation that accompanied your array.

1. Navigate to the Storage Manager network address in an Internet Explorer window, and then log in to the client with an account that has administrative privileges.

2. Select the array where logical disks and pools need to be created, click File, highlight Configuration

Settings/References, and then click Configuration Setting.

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 PathManage r 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.
