Introduction

Product introduction

The EMC® VNX VG2/VG8 servers are network-attached storage (NAS) gateways that connect to EMC Symmetrix arrays or both.

In the VG2 and VG8 systems, a blade (or Data Mover) is a logical identifier that is defined as a CPU module with associated I/O modules.

The VG2 system is equipped with one or two blades; the VG8 system has two to eight blades. If two blades are equipped, the NAS installation software automatically configures one blade as a standby for high availability.

Note: This document uses the terms blade and Data Mover interchangeably.

Each VG2/VG8 system can have one or two Control Stations.

A fabric-connected VNX gateway is cabled to one or more Fibre Channel (FC) switches or Fibre Channel over Ethernet (FCoE) switches by using fiber-optic cables and small form-factor pluggable (SFP) optical modules. The VNX gateway then connects through the Fibre Channel fabric to one or more arrays.

Other servers may also connect to the arrays through the fabric. You can use a single switch, or for added redundancy, you can use two switches. The VNX server can be installed anywhere in the fabric as long as it has a path to the storage array.

(DMX™, VMAX™, or VMAXe™) or VNX storage

A direct-connected VNX gateway is directly cabled to the storage area network (SAN) ports of the storage processors (SPs) of a storage array by using fiber-optic cables and SFPs. Other hosts can connect to the remaining SAN ports of the array, either directly or through a Fibre Channel switch. FCoE is not supported for direct-connected gateways.

If you are connecting the VNX gateway to more than one array, the gateway requires one storage array on which to load the VNX operating environment (VNX OE) and configure for booting the blades. This primary array should be the highest-performance system and must be set up first. The other arrays cannot be used to boot the blades and must be configured after the other setup steps are complete.

If the VNX configuration includes a Symmetrix array, the Symmetrix system should always be the boot array. Advanced Symmetrix features, such as Symmetrix Remote Data Facility Symmetrix array. Symmetrix DMX, Symmetrix VMAX, and Symmetrix VMAXe arrays are supported.

The Celerra Network Server Concepts Guide contains an overview of VNX servers. The Celerra Network Server System Operations technical module provides information on operating a VNX server.

The customer may have ordered the system with an EMC cabinet. Systems ordered with a cabinet have all components installed in the cabinet and most cables connected at the factory. Otherwise, you will install the individual system components in an existing cabinet at the customer’s facility.

(SRDF®), are supported only when the VNX gateway boots from the

EMC VNX VG2/VG8 Gateway Configuration Setup Guide

Setup process overview

Installation and configuration of a VNX VG2/VG8 gateway is typically done in three phases:

◆ Phase 1: Plan the installation and collect configuration information from the

customer. The customer completes site preparation.

◆ Phase 2: Cable hardware to the customer’s SAN, local area network (LAN), and

power system; install the software; and configure the Control Station and ConnectHome. At this point, the system is functional but cannot be used by clients to store and retrieve files.

◆ Phase 3: Configure client network connections, file systems, shares, exports, and

so on. When this phase is complete, the system is fully usable by clients. Instructions for Phase 3 of the setup process are presented in Chapter 10,

“Complete Phase 3 Installation.”

Multiple individuals from different EMC or authorized service provider organizations may work together to complete the different phases of the installation. If the individuals are not at the customer’s site at the same time, it is critical that they provide each other the information needed for each phase.

EMC CONFIDENTIAL

Introduction

Phase 1: Planning and data collection

The first phase starts when the customer agrees to the installation and ends when all of the required information has been collected. Missing information, such as IP addresses, can cause significant delays later in the installation process:

1. Follow the EMC Change Control Activity (CCA) process to obtain an approval for the VNX installation. The CCA requirements may be found on the NAS Support website or the EMC Services Partner website. An approved CCA will direct you as to where and how to obtain the correct version of EMC NAS software to use in the installation.

2. Review the VNX release notes for the version of EMC NAS software specified by the CCA for this installation. Release notes are available from the EMC

Powerlink

website. Pay special attention to any installation-related items.

3. Verify that the customer has completed all site preparation steps, including providing appropriate power and network connections.

4. If the VNX gateway is being connected to a new array, verify that the array has been installed and configured before starting to install the VNX gateway. Verify that the required revision of the array software is installed and committed.

5. Fill out the configuration worksheets with the customer.

6. Give the Phase 2 configuration information to the installer who will complete the next phase.

Setup process overview

EMC CONFIDENTIAL

Introduction

Phase 2: Physical installation and initial configuration

The second phase includes physically installing the system if it did not ship in an EMC cabinet, cabling the system to the customer’s network, installing the NAS code, and configuring the Control Station and ConnectHome. The second phase is complete when the system successfully calls home and you have filled out the “Phase

2 completion hand-off worksheet” on page 282.

Always install and configure the system according to the instructions in this guide. Ensure that you follow the steps in the order given.

To install a VNX gateway:

1. Verify that you have received the required Phase 2 configuration information from the individual who completed Phase 1.

2. Verify that all required components are on site.

3. For systems that shipped without a cabinet, install the components in the customer's cabinet. Chapter 3, “Install Components in Customer’s Cabinet,” provides more details.

4. For systems that shipped without a cabinet, connect the system cables (Fibre Channel, network, and power cables). For factory-cabled systems, verify that the cables are connected correctly. Connect additional cables if necessary.

5. Power on the system and verify the software revisions. Install software as needed. You will need your service laptop computer.

6. Configure the primary Control Station 0 (CS 0).

7. Configure and test ConnectHome.

8. Enable licenses in the EMC Unisphere™ interface for features that you require (for example, Network File System (NFS)).

Introduction

Phase 3: Final configuration

The third and final phase includes all of the configuration required to make the VNX gateway available to clients. The specific steps depend on which services the customer purchased. For example, a customer may elect to have only one initial file system created, or may choose an advanced configuration with multiple file systems, advanced networking configurations, and so on.

The required and optional steps of Phase 3 are documented in Chapter 10, “Complete

Phase 3 Installation.”

Required for all configurations

The following steps are required for all configurations:

1. Configure storage.

2. Run the Setup Celerra Wizard to configure Control Station, blades, network services, and interfaces. Also, create file systems and share file systems. Create exports, netgroups, and users.

3. Generate SSL certificates.

Optional

The following steps are optional for all configurations:

◆ Add or remove arrays.

◆ Upgrade server software to correct a failure of the backend storage requirements

check.

◆ Configure EMC VNX Replicator™.

The third phase is complete when all planned configuration steps are complete and the customer has signed off the implementation phase.

All VNX gateways have the EMC NAS software loaded on the Control Station internal drive at the factory. Like other gateways, the NAS software is never installed on the array, even if the system is delivered in a cabinet from the factory with a VNX array.

The factory always loads the latest software on the Control Station at the time of manufacture. However, the installation can take place several months after the hardware was shipped, so it is very important to install the latest software version.

VNX server blades do not have any internal storage. They boot their operating environment from a designated area on a Symmetrix or VNX array. Although a VNX gateway can store data on several arrays, it always boots from one array, called the boot array in this guide.

The designated area on the array that stores the blade operating system and other related files is referred to as the system LUNs or sometimes control LUNs.

Note: Appendix F, “Manually Zone Switches and Configure System LUNs,” includes the

instructions for manually zoning switches and creating the system LUNs if the target array does not meet the auto-configuration requirements, or if the customer has specific policies that cannot be met by using auto-configuration, or if the array is connected to an FCoE switch.

The Control Station in the VNX VG2/VG8 gateways does not boot from the array. The Control Station stores copies of its configuration data on the array, but the Control Station boots from an internal disk drive. Therefore, you can boot the Control Station of the VNX gateway even if there is no connection to the boot array.

Because the blades boot from the array, any problem with the connection between the blade and the boot array can prevent the blade from booting. Appendix D, “Resolve

Blade Boot Failures,” explains what to do if the blades cannot boot.

VNX arrays When connected to an FC switch, a VNX boot array must be installed and can be

auto-configured during the installation. However, auto-configuration is not supported when the VNX boot array is connected to an FCoE switch.

For VNX arrays, the system LUNs can be created automatically during the VNX gateway setup process.

Symmetrix arrays A Symmetrix boot array must be installed and manually configured before installing

the VNX gateway. Symmetrix DMX, VMAX, and VMAXe are supported arrays for VNX gateways.

Also, EMC generates a new bin file to create the system LUNs. For more information, see:

Introduction

Installing software in the field

PXE booting blades

Assigned blade identifiers

To install the NAS software on the VNX gateway as part of a new installation, you need installation media with the correct software version. Do not use the NAS software media that shipped with the system—it may contain a software version that is out-of-date. The required software version should be verified as part of the Change Control Authorization (CCA) process prior to installation.

The Control Station runs an EMC-customized version of the Linux operating system. You can install the NAS software from authorized EMC NAS installation media.

When the correct NAS software version is installed on the Control Station, you power up the blades for the first time. The blades cannot boot from the array because the array does not have the EMC NAS software installed. Instead, the blades boot from the Control Station over the private LAN connections. This is called PXE (preboot execution environment) or network booting.

During this boot process, the blade BIOS and POST versions are automatically upgraded if needed.

The blade identifiers are based on the enclosure number. Blade enclosure 0 houses blades 2 and 3. (The Control Station reserves ID 0 and 1 for itself, and for this reason, the first blade has an ID of 2.) The right-most blade in a blade enclosure (viewed from the rear) has the lower blade number. Figure 6 on page 37 shows this detail.

A VG2 system has up to two blades (blades 2 and 3) in a single blade enclosure (enclosure 0). A VG8 system has between two and eight blades (housed in one, two, three, or four blade enclosures). In a VG8 system, enclosure 0 houses blades 2 and 3; enclosure 1 houses blades 4 and 5; and so on.

Configuring the private (internal) LAN

The VNX VG2/VG8 gateway uses two fully redundant private (internal) LANs for communication between the Control Stations, enclosure management modules, and blades. These private LANs use IP addresses in two subnets. A dynamic host configuration protocol (DHCP) service on the Control Station assigns addresses to each component on the private LANs. However, the address assigned to a component is always the same.

Note: During fresh installs of NAS software, the private LAN addresses can be changed, if required; otherwise, the installation program uses default addresses.

The default subnets are:

◆ 128.221.252.nnn — This subnet is the primary private LAN. It connects to the

ports (eth0) labeled A on the Control Stations and to the management module ports on the right side of the blade enclosures, when viewed from the rear.

◆ 128.221.253.nnn — This subnet is the backup private LAN. It connects to the port

(eth2) labeled B on the Control Stations and to the management module ports on the left side of the blade enclosures, when viewed from the rear.

◆ 128.221.254.nnn — This subnet is for the intelligent platform management

interface (IPMI) between two Control Stations. The IPMI enables one Control Station to monitor and reboot the other. The subnet consists of a crossover cable between ports labeled CS on the two Control Stations.

Note: Blade 3 is optional for the VG2 but required for the VG8. Blades 4–9 do not apply to the VG2.

It is best to change the internal IP addresses of the VNX gateway from the system defaults during installation. Changing the private IP addresses after the installation is a complex process that involves blade downtime. Appendix B, “Change IP

Addresses,” provides steps to change the VNX gateway internal IP address after

installation.

If the customer is already using these default subnets in their public network, the private LAN addresses should be changed at the installation time. Even though the private LAN does not connect to the customer’s public LAN, the blades and Control Station connect to both networks.

Note: If a customer has multiple VNX gateways, each system can have the same set of private LAN addresses. A conflict occurs only if the same network exists in both the public and private LANs. All VNX gateways attached to the same VNX array must have unique network addresses in the Initiator Record Host IP Address field in the Unisphere interface to ensure that the Host display for those VNX gateways appears correctly.

During the Control Station configuration, you can accept the defaults or enter different addresses for the Control Station private LAN ports. The other components are automatically configured to match. The new private LAN addresses must:

◆ Use a subnet mask of 255.255.255.0.

◆ Be in a subnet that is not used in the customer’s public network.

Introduction

For example, if you set the primary private address for the Control Station (default

128.221.252.100) to 10.12.17.100, then the primary private addresses are set to:

◆ 10.12.17.2 for blade 2

◆ 10.12.17.4 for blade 4

◆ 10.12.17.50 for the enclosure 0 right-side management module

◆ 10.12.17.100 for Control Station 0

The same rules apply to the backup subnet.

“Private LAN worksheet” on page 280 provides details for the default addresses. If

you need to change the private LAN addresses, record the new values in this worksheet.

Zoning FC switches

Once the blades have been network-booted, the Control Station collects the World Wide Names (WWNs) of the Fibre Channel ports in the blades. A WWN identifies a port in a Fibre Channel fabric, much like a MAC address in an Ethernet network, and is based on the enclosure WWN seed value. The WWNs are used to zone the Fibre Channel switches.

When selected, the auto-configuration script automatically sets up the Fibre Channel switch zones by using single initiator zoning. The auto-configuration script configures each gateway blade with four zones (each blade port is zoned to one port on each SP).

The script prompts for the network address and login credentials of each switch. The setup script supports Fibre Channel switches from the following manufacturers: McDATA, Brocade, and Cisco. Refer to the EMC E-Lab™ Interoperability Navigator on Powerlink for supported firmware revisions of your switch. If a Fibre Channel switch works with the VNX gateway, then it will work with auto-configuration.

The setup script cannot automatically zone the FC switch if:

◆ The switch password is still set to its default value. Set the switch password to a

value other than the default before using the script.

◆ The switch contains uncommitted zones or configurations. Commit or delete

these zones or configurations before you continue. This prevents the setup script from overwriting any existing fabric zoning, or configurations the customer might want saved but has not committed to the configuration.

◆ The gateway system has a 10 Gb FCoE I/O module in slot 0 of the VNX blade

enclosures. See “Zoning FCoE switches” on page 28.

If the auto-configuration script cannot zone the customer’s Fibre Channel switches, or if the default zoning is not acceptable, then you can manually zone the switches. Manual zoning uses the administration program provided by the switch manufacturer.

The correct switch zoning enables the blades to communicate with the arrays over the Fibre Channel fabric. By default, each blade is zoned to each SP on a VNX array. For Symmetrix arrays (DMX, VMAX, and VMAXe), each blade is zoned to two different channel directors.

Note: You must manually zone the FC switch if you are using a Symmetrix array for the boot array. Appendix F, “Manually Zone Switches and Configure System LUNs,” provides information about manually zoning the FC switch.

Introduction

Zoning FCoE switches

Creating Host LUNs

The VNX VG2 and VG8 gateways can be connected to the following Fibre Channel over Ethernet (FCoE) switches: Connectrix MP-8000B (Brocade), Cisco Nexus 5010, and Cisco Nexus 5020. To connect to an FCoE switch, the gateways require a 10 Gb FCoE I/O module in slot 0 of the VNX blade enclosures.

Note: If connecting a Cisco switch, configure the switch parameter “no errdisable detect cause all” for optimal performance.

You must manually zone the FCoE switches (no auto-configuration script exists for zoning FCoE switches). Manual zoning uses the administration program provided by the switch manufacturer.

Note: Appendix F, “Manually Zone Switches and Configure System LUNs,” provides

information about manually zoning the FCoE switch.

The correct switch zoning enables the blades to communicate with the arrays over the Fibre Channel fabric. By default, each blade is zoned to each SP on a VNX array.

For information on FCoE switch configurations, refer to the EMC Techbook: Fibre Channel over Ethernet (FCoE) on the EMC Powerlink website.

Tab le 2 lists the Host LUN values that you need to use for the VNX. The LUNs must

be created and masked to the VNX unless you are using auto-configuration. Auto-configuration works for direct-connected gateways or fabric-connected gateways that connect to an FC switch. Gateways that are connected to an FCoE switch must be manually configured as described in

Switches and Configure System LUNs.”

After the switches are zoned, the Control Station can install the NAS software to the system LUNs on the boot array. This installation is part of the setup script running on the Control Station.

Note that a Control Station cannot copy data directly to an array. The Control Station does not have a Fibre Channel host bus adapter (HBA). Instead, the Control Station uses an EMC-proprietary system called network block service (NBS), which is explained in the following section.

Introduction

Understanding the network block service

Figure 1 Network block service

The network block service (NBS) enables the Control Station to access LUNs on an array. For example, the Control Station uses NBS to read and write its database information stored in the system (or control) LUNs, and to install NAS software on the array.

NBS data is sent from the Control Station to a blade over a private LAN connection. The blade then sends the data to the array over the Fibre Channel connection.

Figure 1 shows the physical path used for the virtual NBS connection.

Configuring dual Control Stations

An NBS client daemon on the Control Station communicates with the NBS server on the blades.

The Control Station must have at least one blade running normally and accessible over the local network to run any administrative commands. Administration is not possible without the NBS connection.

Array management traffic between the Control Station and the array does not use the NBS service.

A VNX VG2/VG8 gateway optionally has a second Control Station for high availability. At installation time, CS 0 is the primary CS, and CS 1 is the standby. After installation, CS 0 is always the active CS. If the primary CS fails, the standby becomes primary. The former standby remains primary until another failure or reboot. Therefore, at any time, depending on the circumstances, either CS may become primary.

Network connections to dual Control Stations can use IP aliasing. This enables the administrator to contact the primary Control Station with a consistent address, regardless of which physical Control Station is primary. The Celerra Network Server System Operations technical module provides details for IP aliasing instructions.

A complete software installation is first performed on CS 0 (CS 1 must be powered down and its power cable disconnected). When that installation is complete, you perform the software installation on CS 1. When the installation on the second Control Station is complete, CS 0 is primary and CS 1 is in standby mode. The software setup script prompts you about installing the secondary Control Station; it does not detect this automatically.

Introduction

Note: Both Control Stations must be running exactly the same version of the EMCNAS software. You should verify the software on both Control Stations, even if the first one you check has the correct version.

Booting blades from the array

Remaining setup steps

Unisphere interface

After the Control Station has installed the NAS software on the array, the blades are rebooted. This time, the blades boot from system LUN 0 on the array. During this boot process, the blade BIOS and POST versions are automatically upgraded if needed.

If Fibre Channel configuration problems exist, you would encounter them now. Problems such as incorrect zoning, incompatible switch software versions, or incorrect array initiator records can cause the boot to fail.

The remaining steps set the configuration values, and then create the user volumes. These steps are typically performed by using the Setup Celerra wizard in the EMC Unisphere interface. The Setup Celerra wizard walks you through the various settings—you can perform the same tasks by using the CLI. EMC recommends that you use the Setup Celerra wizard to prevent accidentally skipping a required setting.

Chapter 10, “Complete Phase 3 Installation,” provides information on the Setup

Wizard.

User tasks that require a user interface are performed by using the EMC Unisphere™ interface. The Unisphere interface replaces the Celerra Manager and Navisphere Manager interfaces of earlier releases. However, if the backend array is using FLARE release 29 or earlier, Navisphere Manager is required for some of the backend tasks.

Appendix I provides the procedures to perform these tasks.
