Preface

About this guide

This guide describes the following tasks and topics:

Preparing to install an F800 or a FAS900 series cluster
Cabling a pair of F800 or FAS900 series appliances into a cluster
Configuring the cluster when you first bring it up
Performing basic troubleshooting on the cluster

This guide does not cover basic system or network administration, which is covered in the Data ONTAP^TM System Administration Storage Management Guide. This is primarily a cluster hardware guide covering hardware clustering issues. Some basic software commands are also covered in this guide. See the Data Protection Guide or Storage Management Guide for more information about clustering software and commands.

Audience

This guide is for qualified system administrators and service personnel who are familiar with Network Appliance^TM equipment and who need to

Cable two systems into a standard or mirrored cluster system
Convert stand-alone systems into a standard or mirrored cluster system
Cable a new Fabric Attached or nonswitched MetroCluster.

Terminology

This guide uses the following terms:

FAS900 refers to NetApp appliances belonging to that series, such as the FAS980c.
F800 refers to NetApp filers belonging to that series, such as the F880c.
Mirrored cluster refers to a cluster where there are 2 copies, or plexes, of the data.
Fabric Attached MetroCluster refers to a cluster running syncmirror_local and cluster_remote, where the nodes and disk shelves are attached to two pairs of Fibre Channel switches, where the nodes and disk shelves are not cabled together in standard cluster fashion, and where the nodes are separated by more than 500 meters and up to 30 kilometers.
Nonswitched MetroCluster refers to a cluster running syncmirror_local and cluster_remote, where the nodes are separated without a switch by more than 30 meters and up to 500 meters.
Node refers to either the local or partner appliance.
FC HBA for Disk or FC HBA refers to the Fibre Channel host bus adapter that connects the node to the switch or to the disks.
Appliance refers to any F800 series filer or FAS900 series appliance.
Disk shelf refers to a Fibre Channel StorageShelf FC7, Fibre Channel StorageShelf FC8, Fibre Channel StorageShelf FC9, or Fibre Channel DiskShelf14/DS14mk2.
LRC refers to the device that combines the LRC (Loop Resiliency Circuit), which keeps the FC-AL loop intact during the addition and removal of disks within a disk shelf and the enclosure services processor, which communicates the environmental data of the disk shelf.
ESH refers to the device that combines the ESH (Embedded Switch Hub), which provides high availability should a disk fail, and the enclosure services processor, which communicates the environmental data of the disk shelf.
ESH2 refers to a second-generation ESH (Embedded Switch Hub 2) module.

Command conventions

You can enter commands on the system console or from any client that can obtain access to the filer using a Telnet session. In examples that illustrate commands executed on a UNIX® workstation, the command syntax and output might differ, depending on your version of UNIX.

Keyboard conventions

This guide uses capitalization and some abbreviations to refer to the keys on the keyboard. The keys on your keyboard might not be labeled exactly as they are in this guide.

What is in this guide...	What it means...
hyphen (-)	Used to separate individual keys. Example Ctrl-D means holding down the Ctrl key while pressing the D key.
Enter	Used to refer to the key that generates a carriage return, although the key is named Return on some keyboards.
type	Used to mean pressing one or more keys on the keyboard.
enter	Used to mean pressing one or more keys and then pressing the Enter key.

Formatting conventions

The following table lists the kinds of formatting this guide uses to identify special information.

Formatting convention	Type of information
Italic type	Words or characters that require special attention. Placeholders for information you must supply. For example, if the guide requires you to enter the `arp -d hostname` command, you enter the characters "arp -d" followed by the actual name of the host. Book titles in cross-references.
`Monospaced font`	Command and daemon names. Information displayed on the system console or other computer monitors. Contents of files.
`Bold monospaced` font	Words or characters you type. What you type is always shown in lowercase letters, unless you must type it in uppercase letters for it to work properly.

Special messages

This guide contains special messages that are described as follows:

Note
A note contains important information that helps you install or operate the system efficiently.

Caution
