Chapter 6. Administration - Enterprise Management

6.1 Enterprise Management window overview

When you launch Storage Manager, you get the Enterprise Management window (shown in

Figure 6-2 on page 159), and also, by default, the Task Assistant.



6.1.1 Initial Setup Tasks

Initially, the Initial Setup Tasks window displays as shown in Figure 6-1. The Task Assistant

gives you a quick way to access common tasks.



Figure 6-1 Setup Tasks



You can access these common tasks from this window, or you can use the Storage Manager

itself. Here is a list of the functions provided in Setup Tasks, with information about where the

use of these functions is described in this book:

Initial Setup Tasks:

– Add Storage Subsystems: See 5.2, “Installing DS Storage Manager on Linux” on

page 140 or “Add Storage Subsystem to view” on page 173.

– Name/Rename Storage Subsystems: See 12.3, “Rename Storage Subsystem” on

page 299.

– Configure Alerts: See “Configure Alerts” on page 164.

IBM System Storage DS3500 Introduction and Implementation Guide



Subsystem Management:

– Manage a Storage Subsystem: Starts the main Storage Manager application, as

described in the following chapter.

– Upgrade Controller Firmware: Upgrades firmware on multiple storage subsystems, as

described in Chapter 14, “Administration - Support” on page 329.

Accessibility:

– Inherit System Settings: Inherits system settings for color and fonts, which allows the

IBM System Storage DS software to use settings defined through operating system



6.1.2 Enterprise Management window

The Enterprise Management window (Figure 6-2) is the entry point to manage each DS3500

storage subsystem. We described how to add storage subsystems in 5.4, “Completing the DS

Storage Manager installation” on page 151. After they have been added, they will appear

every time you start Storage Manager.



Figure 6-2 Enterprise Management window



The Enterprise Management window displays a list of all DS3500 storage subsystems that

you can access either directly or through the host agents. If you can access a certain storage

server in both ways, and possibly through several host agents, you see it listed not just once,

but many times in the Enterprise Management window.

Note: Although a single storage server could appear listed several times in the left pane

when it is accessed by various host agents or directly attached, it only appears once in the

right pane.

In the left window pane, you see your management station, and your managed subsystems.

The subsystems are divided into two groups: In-Band Storage Subsystems and Out-of-Band

Storage Subsystems. You can also see the status of your subsystems in this pane. If your

subsystem appears green, the status is optimal. If you highlight the subsystem in the left part

of the window, you also see a short summary of this system in the right window pane. If the

subsystem appears red in this view, then it needs attention. What you do in this case is

described in Chapter 14, “Administration - Support” on page 329.

Status



Indicates



Optimal



Every component in the managed storage subsystem is in the desired working

condition.



Needs Attention



There is a problem with the managed storage subsystem that requires

intervention to correct it.



Fixing



A Needs Attention condition has been corrected and the managed storage

subsystem is currently transitioning to an Optimal state.



Unresponsive



The storage management station cannot communicate with the storage

subsystem, or one or both controllers in the storage subsystem.



Contacting

Storage

Subsystem



The Enterprise Management window has started an the storage management

software is establishing contact with the storage subsystem.



Needs Upgrade



The storage subsystem is running a level of firmware that is no longer supported

by the storage management software.



6.2 Functions in the Enterprise Management window

Next, we describe the various functions that are available from the Enterprise Management

window.



6.2.1 Subsystem context menu

Right-click one of the subsystems to see the context menu with the tasks as shown in

Figure 6-4 on page 161.

IBM System Storage DS3500 Introduction and Implementation Guide



Figure 6-4 Context menu



Manage Storage Subsystem

This opens the Subsystem Management window. You can also double-click the system to

manage it.



Locate Storage Subsystem

If you have several storage subsystems installed, it can be hard to locate the right one. If you

select this option, the indicator light on the selected subsystem starts flashing (Figure 6-5).



Figure 6-5 Indicator lights are flashing



Execute Script

Here you can open the DS3500 Script Editor. This Editor can be an effective and useful tool to

manage your subsystem. For more information about how to use it, see 17.2.1, “Script Editor”

on page 521.



Load Storage Subsystem Configuration option

In 17.7.1, “Sample command: Save configuration script file” on page 534, we describe how to

save a configuration script file based on the current environment. This is done on the CLI

Chapter 6. Administration - Enterprise Management



161



using the save StorageSubsystem configuration command. With the Load Storage

Subsystem Configuration option in Storage Manager, you can load a saved file so that the

configuration is applied to another storage system

This option will append the uploaded configuration to your storage subsystem unless you do

either of the following operations:

Reset the storage subsystem’s configuration before loading the new one.

Edit the saved script so that it contains the reset configuration command.

To upload a configuration file, do the following steps:

1. Select this option, and the load configuration notes will appear. Read them carefully, and

then click Yes.

2. The Script Editor will open. Select your configuration file and click OK.

3. Now the file gets loaded into the Script Editor and the Confirm Load Configuration window

appears:

a. If you want to append a configuration to the existing one, click Execute, and the script

will append the uploaded configuration to the existing one.

b. If you want to restore your subsystem’s configuration before the new one is uploaded,

select Edit and look in the Script Editor for the lines shown in Figure 6-6 and

uncomment them. After uncommenting these two lines, select Tools  Verify 

Execute from the Menu bar to execute the script and upload the new configuration.

show “Deleting the existing configuration.”;

set storagesubsystem resetConfiguration = true;



Figure 6-6 Uncomment lines to delete the existing configuration before uploading a new one



Existing configurations: The script will not overwrite an existing configuration, that is, the

script will fail if it attempts to build an array using drives that are already part of an existing

array.

However, if you have lost an array that had data stored on it, do not reapply the

configuration using this script because it will initialize the drives and delete the data.

Instead, you should contact IBM technical support to see if your data can be recovered.



162



IBM System Storage DS3500 Introduction and Implementation Guide



Note: To save time, use the load configuration file option for new DS3500s using a

previously created file for an existing DS3500. For example, if you have a number of

storage subsystems with similar configurations, you can configure one, save the

configuration file, modify it if necessary (for example, to use a separate storage subsystem,

or define different hosts), then use it to quickly configure the remaining storage

subsystems.

You could also use this option to re-create replacement DS3500s if your original hardware

was destroyed in a disaster.



Upgrade Controller Firmware

Select this option to upgrade the firmware of the controllers in the storage subsystem. In the

process of upgrading the firmware, the firmware file is downloaded from the host to the

controller. After downloading the firmware file, you can upgrade the controllers in the storage

subsystem to the new firmware immediately. Optionally, you can download the firmware file to

the controller and upgrade the firmware at a more convenient time.

The process of upgrading the firmware after downloading the firmware file is known as

activation. During activation, the existing firmware file in the memory of the controller is

replaced with the new firmware file. The firmware upgrade process requires that the

controllers have enough free memory space in which the firmware file can reside until it is

activated.

The Upgrade Controller Firmware window and the Download Firmware dialog are shown in

Figure 6-7.



Figure 6-7 Upgrade Controller Firmware



You also can use the command line interface (CLI) to download and activate firmware to

several storage subsystems.

Refresh

Select this option to refresh the view of the Enterprise Management window (Figure 6-8). You

might use this if a system’s status has changed, for example, after an error recovery.



Figure 6-8 Refresh View



Remove

Here you can remove the selected storage subsystem from your view. This will not affect the

views of any other storage management stations. To remove a storage subsystem, select this

option and click OK (Figure 6-9).



Figure 6-9 Remove Subsystem



Configure Alerts

The IBM System Storage DS3500 Manager includes the Event Monitor Service, which

enables the host running this monitor to send out alerts through email (SMTP) or traps

(SNMP). The Event Monitor can be used to alert you of critical events for any of the DS3500

storage subsystems in your environment. For high availability, the event monitor service

should run on two separate host systems that are available 24 hours a day. Both servers

should be capable of out-of-band and in-band management. This ensures proper alerting

even if one server is down or a connection type has failed.

Note: The DS3500 does not send the email or SNMP trap itself. The management station

(running the event monitor service) sends the notification on behalf of the storage server. If

the management station is down, no alerts will be sent.



164



IBM System Storage DS3500 Introduction and Implementation Guide



What systems are monitored

Depending on how you set up alerts, different storage systems are monitored by the Event

Monitor.

Alerts can be configured as follows:

– To configure alerts for all storage systems listed in the Enterprise Management

window, right-click your local management system in the Enterprise Management

window (at the top of the tree) and select Configure Alerts, as shown in Figure 6-10.



Figure 6-10 Configure Alerts for all systems



– If you can see the same storage subsystem through separate paths, directly attached,

and through different hosts running the host agent, you will receive multiple alerts.

Right-click a specific storage system to define the alerting specifically for this storage

server, as shown in Figure 6-11 on page 166.



Chapter 6. Administration - Enterprise Management



165



Figure 6-11 Configure Alerts for particular subsystem



– Select Configure Alerts for one or more systems and the alert window as shown in

Figure 2 on page 167 appears.



E-mail alerts

Here we discuss how to work with email alerts:

1. To send email alerts, you have to first define an SMTP server. Enter the name or IP

address of your mail server and the sender email address as shown in Figure 2 on

page 167.



166



IBM System Storage DS3500 Introduction and Implementation Guide



Figure 6-12 Configure Alerts - define mailserver



2. Select the Email tab to configure the email address to which the alerts are sent. Enter the

email addresses and click Add as shown in Figure 6-13 on page 168.



Chapter 6. Administration - Enterprise Management



167



3. Now your window should look similar to Figure 6-13. In the drop-down menu next to the

Address, you can select which information should be sent and how often the data should

be delivered. If you highlight an Address, you can also send a test email to validate that

your configuration is working.



Figure 6-13 Configure Alerts - Defining email address



SNMP alerts

Similarly, select the SNMP console for receiving and handling the traps sent by the service.

Enter your community name and the destination dress of your SNMP Server and click Add,

as shown in Figure 6-14 on page 169.
