- Notification list interface
- Notification Manager event viewer and events

### Introduction

The Notification Manager is a tool used to notify other systems running the ServeRAID Manager of all events that occur on this (that is, the local) system. The user of the system types system names in the notification list. Each system in the list is notified of all events that occur on the local system.

#### An example

You install SystemA in a lab with a ServeRAID subsystem. You run the ServeRAID Manager on SystemA to monitor for events and problems, but you want to monitor from your workstation and not from SystemA. You open the SystemA Notification Manager from the ServeRAID Manager and define your workstation in the notification list. When running the ServeRAID Manager from your workstation, you are notified of all problems and events that occur on SystemA.

#### The Notification Manager and its events

Events generated by the Notification Manager include:

- Progress information, such as rebuilds, synchronizations, and migrations.
- Problems, such as defunct disk drives and PFA errors.
- Changes to the local configuration, such as creating a hot spare or defining a logical drive.

The Notification Manager consists of the following:

Tool bar | Provides quick-path icons for common tasks.
Notification list | Displays the remote systems configured to receive event notification.
Notification event viewer | Displays status information for the Notification Manager.

When an event is generated on a system, the Notification Manager connects with each system in the notification list and relays the event to these systems' ServeRAID Manager. If the Notification Manager successfully connects and sends the event, the notification list updates its Last event sent column. If the Notification Manager does not successfully connect or send the event, the notification event list:

- Updates the Last event sent column with an notifying you of a problem.
- Logs an event in the Notification Manager event viewer detailing why the event could not be sent.

### Notification list interface

The notification list has four columns:

Host name | The TCP/IP host name to notify for each event. If you double-click this column, the Modify system properties window opens.
TCP/IP address | The TCP/IP address to notify for each event. If you double-click this column, the Modify system properties window opens.
Port | The TCP/IP port number the ServeRAID Monitor uses to communicate with the remote system ServeRAID Manager. If you double-click this column, the Modify system properties window opens.
Last event sent | The last date and time the Notification Manager sent, or tried to send, an event to a system. If you double-click this column, the Last event sent window opens. If the Notification Manager did not successfully send the event to the system: An event is logged in the Notification Manager event viewer. An displays in this column.

### Notification Manager event viewer and events

The Notification Manager event viewer has four columns. You can double-click any event in the event viewer and the Notification event detail window opens. The window contains the same information as the event viewer, but in a larger, easier-to-read window.

Type | The type of event (that is, Information, Warning, or Error).
Date | The date the event occurred.
Time | The time the event occurred.
Host name | The system for which the event was generated.
Notification event description | The event description.

In addition to displaying the events in the event viewer, the Notification Manager appends each event to a logging file, RAIDNOT.LOG. If this file exceeds 200 KB, the Manager copies the file to RAIDNOT.OLD and creates a new RAIDNOT.LOG. If there is a RAIDNOT.OLD already, the Manager overwrites it.
