What is Celerra Manager?

Celerra Manager is Web-based software that allows you to configure, administer, and monitor the

Celerra Network Server. By consolidating the management of multiple devices into one GUI, Celerra

Manager gives you an overall view of what is happening in your environment. Wizards offer the

opportunity to simplify the completion of administrative tasks.

The Celerra Manager interface, shown above, has two main areas. From the navigation pane on the

left, you select the file server and feature you want to manage. The task page on the right displays the

options available to manage the selected feature. Many task pages include tabs you can click to view

different information about a feature or device.

� Connect with a Web browser and use Control Station IP address

(HTTPS)

– Username and password required (discussed later)

� Supported Web browsers

– Internet Explorer 6.0 SP2

– Netscape 6.2.3 or later (EMC recommends using Netscape 7.1 or later)

– Firefox 1.5 or later

� Disable pop-up blocking entirely or allow pop-ups for the site

� Java Runtime Environment (JRE) 1.5.0_12 recommended

� CAUTION:Using the browser Back button does not update or refresh Celerra Manager pages correctly

� To refresh the Web Browser use the Refresh Button

Java Runtime Environment

EMC strongly recommends the use of Java Runtime Environment (JRE) 1.5.0_12 revision on client machines that will run Celerra Manager. You can get an installable version of JRE 1.4.2 from the Sun Microsystems website at http://java.sun.com/j2se/1.4.2/download.html, or from the Celerra Applications and Tools CD.

The use of Celerra Monitor, provided with Celerra Manager - Advanced Edition, requires installation on the client computer of the Java Web Start package. This package is part of JRE 1.5.0 revisions.

Note: You can use JRE 1.4.0, 1.4.1, or 1.4.2 with Celerra Manager, but you may see performance issues with these earlier revisions.

A bug in version 1.4.2 of the Java Runtime Environment (JRE) sometimes causes the browser to crash when switching between objects in the navigation pane in Celerra Manager or when clicking rapidly without giving the browser time to respond.

Internet Explorer

EMC requires the use of Internet Explorer 6.0 SP2 to run Celerra Manager.

Netscape

EMC requires the use of Netscape 6.2.3 or later to run Celerra Manager. For the best Netscape experience with Celerra Manager, EMC recommends using Netscape 7.1 or a later 7.x revision.

CAUTION: Celerra Manager is not supported with Netscape 8.0 or later revisions.

Firefox

EMC requires the use of Firefox 1.5 or later to run Celerra Manager.

Web browser caveats

Some actions in Celerra Manager are designed to open a new browser window. If your browser is set to block pop-ups, these windows cannot open. To use these functions, you must either disable pop-up blocking entirely or allow pop-ups for the site. Also, note that some browsers open a new window in a new tab.

CAUTION: Do not use the Web browser Back button to move around in Celerra Manager. Using the browser Back button does not update or refresh Celerra Manager pages correctly and can produce errors.

Celerra Manager Terms and Locations

� Navigation pane

– Used to select

feature/function

� Tasks page

� Tabs (inside

Tasks)

Basic layout of the Celerra Manager interface

The Celerra Manager interface has two main areas: a navigation pane and a task page.

The navigation pane is on the left side of the Celerra Manager window. It includes the word Celerras at the top and lists the Celerra Network Servers you can manage with the current session. An icon beside each server name indicates its overall status. Use the navigation pane to select the file server and feature you want to manage.

Working in the Navigation Pane - Clicking the plus sign (+) beside a Celerra Network Server name expands the folder to show the features that you can manage on that server. Clicking the minus sign (-) collapses the server folder. Double clicking also expands and collapses the server folder.

The folders for features you do not have licensed are grayed out.

Clicking a feature name in the navigation pane opens its initial management page in the task page. Most often, this page provides a list of manageable components and summary information about each component.

The task page is on the right side of the Celerra Manager window. From left to right, the top of the task page includes the name of the feature with which you are working, your login name on the Celerra Network Server with which you are working (<login_name>@<Celerra_name>), and the icons shown on the slide.

Tabs - Part of the task page, tabs contain different views and/or features you can use to configure what you have selected on the navigation pane.

Overall system status and icons

The overall system status is always visible in icon form in the navigation pane beside the system name

and in the System Status field on the Celerra Home: Status tab. The displayed status is the most

serious hardware component status and software alert status.

The overall system status meanings are:

� Status is being requested from the Celerra Network Server

� OK - Normal operation

� Warning - The system is operating, but possibly not in the intended manner. Investigate and correct

the hardware component or alert that shows a Warning status.

� Error - Something in the system is not operating properly. Investigate and fix the hardware

component or alert that shows an Error status.

� Critical - Something in the system is completely disabled. Investigate and fix the hardware

component or alert that shows the Critical status as soon as possible.

� Cannot determine status - Cannot contact the file server (not logged in or file server is down), or

the file server can be contacted but system status cannot be determined.

� Information - The software facility is operating, but possibly not in the intended manner. Alerts

with the Info status began in another state but were accepted or acknowledged by an administrator.

This action changed the state to Info and prevents the alert from affecting the overall system status.

Celerra Monitor Advanced Edition Only

� Opens separate JAVA applet

� Multiple Celerra systems at the same time

� Used when statistics tab is not enough

� Component view shown below

Celerra Monitor is a Java-based, client/server application that allows you monitor the status of a

Celerra Network Server system.

Using Celerra Monitor, you can:

� Display the status of all Data Movers to assist in ensuring smooth operations.

� Display file system, server, volume, and storage-system configurations.

� Generate a wide variety of performance statistics and measurements.

� Check system logs. Control access and polling of monitored objects.

� Define a customized, user view so you can display only the file systems with which you are

concerned.

� Connect to and monitor multiple Celerra Network Servers at the same time.

The main Component window displays detailed information on the Celerra Network Server you are

connected to and provides navigational capabilities. The data is current from the moment you open the

window and it is refreshed periodically. The time interval when this window refreshes depends on the

number of Celerra Network Servers you are connected to. If you are connected to one Celerra Network

Server, it refreshes every 5 minutes, two Celerra Network Servers refresh every 10 minutes, etc. If you

are displaying a window and need current data to display, click the Refresh button. You can drag

columns to appear in any order you choose. However, the column order you choose will not be saved.

The columns always initially appear in the same order.




Celerra Monitor (cont.)

� Separate

comprehensive help file

� Requires active

production environment

to properly view

information

� No data = Blank charts




Celerra Notifications

� Appears on the Celerra Home, Status tab

� Event notifications

– Based on predefined system events

– Severity levels :Critical, Error, Warning, Info

� Resource notifications

– Based on resource usage parameters you specify

– Storage Usage, Storage Projections, Data Mover Load

� Note: A default file system event and alert when a file

system crosses the 90 percent usage threshold

Notifications specify actions the Control Station takes in response to particular events. For example,

the Control Station can send an email message to an administrator when any critical event occurs.

Event notifications are notifications based on pre-defined system events, such as a temperature being

too high. Severity levels :Critical, Error, Warning, Info

Resource notifications are notifications based on resource usage parameters you specify so you can be

notified of, or in advance of, various resource usage problems. You define the conditions or threshold

for an event that triggers a notification. The notification is sent to the system log, an alert is generated,

which appears on the Celerra Home: Status tab, and optionally, email messages can be sent to

specified users and SNMP traps can be sent to specified hosts.

You can monitor file systems, storage pools, and virtually provisioned file system space to ensure they

do not fill and result in a denial of write access. You can do this by configuring customizable

notifications based on file system and storage pool usage and time-to-fill predictions. These

predictions (otherwise known as projection notifications) can take into account automatic file system

extension (with and without specified maximum sizes) and automatic storage pool extension.




Celerra Notifications (cont.)

� Log files

– Optional email and/or SNMP trap

� Celerra Manager Basic Edition

– view, create, and manage Event notifications

– view resource notifications.

� Celerra Manager Advanced Edition

– view, create, and manage Event, Storage Usage, Storage Projections, and Data Mover Load notifications.

� Image below represents task page tabs after selecting “Notifications” folder in Navigation pane

The success of Data Mover Load notification conditions depends on resource usage patterns. Since

resource usage typically varies greatly throughout a day, it is important to identify peak usage periods

before setting notification conditions. By identifying peak usage patterns, you can choose appropriate

computation methods and intervals to check for overloads. The Data Mover Statistics tab provides

historical Data Mover statistics graphs to help you understand your Data Mover's CPU and memory

usage patterns. These graphs help you determine whether you should create Data Mover notifications

and if so, at what levels to set the limits.

Computation Methods:

Averages Method, SubInterval Method, Percentage Method: When the specified percentage, or more,

of all readings within the specified interval exceeds the limits set, the specified action for the

notification will be triggered.

Fields included:

ID, Data Mover, Interval Start, Interval Length Memory Limit, CPU Limit, Email Addresses for

Notification, and SNMP Traps for Notification.




Celerra Manager Message of the Day (MOTD)

� MOTD banner can be used

for any informational purpose

� Useful for sending messages

that affect all users

– server upgrades

– alert about an impending system

shutdown.

� To change any of the properties on this tab, you

must be logged in as root.

A message of the day (MOTD) banner can be used for any informational purpose, but is particularly

useful for sending messages that affect all users. The message might contain information about server

upgrade or an alert about an impending system shutdown. To change any of the properties on this tab,

you must be logged in as root.

To create a message of the day:

Log in as root

Select Celerras > [Celerra_name].

The Celerra Home: Status tab appears.

Click the Control Stations Properties tab.

The Celerra Home: Control Stations Properties tab appears.

In the Message of the Day field, type or paste the message text to display.

Click Apply.

Note: The message of the day appears in a pop up each time a user successfully logs in. The pop up

contains a checkbox that allows the user to display the message only if it has changed.




Celerra Manager and CLI Interoperability

Working with the CLI from Celerra Manager

The Celerra Manager does not contain interfaces to manage all Celerra tasks, but you can manage

those features using CLI Commands features or open an SSH session to the control station. The CLI

Commands feature allows you to enter a command and view the results but only accepts a single

command at a time.

Some items that can be created using the CLI cannot be managed from Celerra Manager. You may be

able to view these items from Celerra Manager, but will need to use the CLI to modify or delete them.

An example is event notifications that specify individual event identifiers.

When your CLI session is complete, you may need to click the Refresh icon in Celerra Manager to see

the results. Make sure you click the Refresh icon on the Celerra Manager application and not the

browser Refresh icon.
