Overview

This guide steps you through configuring your environment to work with an EMC storage platform in preparation for installing Peer Software solutions. The last section of this guide provides troubleshooting information. During the configuration process, you will be installing and configuring software on the server that will host Peer Software solutions. This server is hereafter referred to as the CEE server. The software you will be installing and configuring includes:

CEE (Common Event Enabler) framework – Required to receive real-time notifications from EMC storage platforms.
.NET Framework – Core Windows software needed to run the CEE framework.
RabbitMQ Server – Message broker required by Peer Software solutions to receive real-time notifications from CEE.
Erlang – Required by Rabbit MQ Server.

Requirements

Your EMC Unity storage device must be running Unity Operating Environment v4.2 or later.
Local administrator rights are required for most of the installation and configuration tasks.
See EMC Unity Prerequisites for other requirements.

Terminology

CEE server – A Windows server hosting CEE framework and your Peer Software solutions.
Common AntiVirus Agent (CAVA) – A software service that provides anti-virus and event-publishing services for EMC storage platforms.
Common Event Enabler (CEE) framework – An EMC software product required to obtain real-time event notifications from a Unity storage platform. Used to be called Celerra Event Enabler.
Common Event Publishing Agent (CEPA) – A software service that provides event publishing services for EMC storage platforms.
NAS Server – An EMC Unity storage server that uses the SMB, NFS, or FTP/SFTP protocols to catalog, organize, and transfer files within designated file system shares.
SMB/CIFS – The Server Message Block (SMB) Protocol is a network file-sharing protocol; it supersedes Common Internet File System (CIFS), an earlier protocol. SMB is used in this document to refer to both protocols.
Unity – All-Flash and Hybrid Flash unified storage platforms.
Unisphere – A web-based application for managing the Unity platform.

Configuration Tasks

Task 1. Confirming Configuration Readiness

Ensure that the EMC Unity prerequisites are met for the Peer Software solution you will be using.
If your storage platform (e.g., Unity and VNX) requires licensing for the Common Event Enabler (CEE) framework, ensure that CEE is licensed.
Ensure that the Unity storage device is already configured to serve data via SMB. You should be able to access an SMB share from a Windows client BEFORE attempting to continue.
Ensure that the date and time on the Unity storage device are synchronized with any associated domains and the CEE server.

Task 2. Installing the .NET Framework on the CEE Server

Troubleshooting

Error 1053 When Starting CAVA Service

If you get Error 1053 when you try to start the EMC CAVA service, ensure that the .NET 3.5 Framework is installed on the CEE server, and then restart the EMC CAVA service on the CEE server.

Starting RabbitMQ Issue

If you experience an issue with starting RabbitMQ, try the following steps:

On the CEE server, open a command prompt as an administrator.
Navigate to the directory where RabbitMQ Server is installed (typically C:\Program\Files\RabbitMQ Server\rabbitmq_server-X.X.X\bin, where X.X.X is the version number).

Enter the following three commands:

rabbitmq-service stop
rabbitmq-service remove
rabbitmq-server start

If the start command results in an error about an Erlang cookie, reset the HOMEDRIVE and HOMEPATH environment variables to a locally accessible folder (such as C:\Users\Public). To set these environment variables:
1. Open a command prompt as an administrator.
2. When prompted to allow changes, click Yes.
3. Enter the following commands in the command prompt window:
```
set HOMEDRIVE=C:
set HOMEPATH=/Users/Public
```
Rerun the following command and verify that no Erlang cookie errors are encountered:
```
rabbitmq-service start
```
Use Ctrl+C to stop the RabbitMQ Server process.
Delete the folder C:\Users\%Username%\AppData\Roaming\RabbitMQ.
Enter the following commands in the command prompt window:
```
rabbitmq-service install
rabbitmq-service start
```
Verify that the folder C:\Users\%Username%\AppData\Roaming\ was recreated and populated with db and log folders.
