Executive Summary

Customers rely on Microsoft Exchange, SQL Server, and various internet/intranet applications as key business applications. Even short periods of unexpected downtime can have a serious impact. The capability of backing up and restoring data quickly and consistently is essential. The problems in backing up large amounts of data, such as backup jobs frequently overflowing their backup window, and having open file and application issues, led to the development of snapshots.

The capability to take snapshots has been around for several years. Snapshots allow administrators to “snap” a copy of data while allowing applications to continue running. Applications are paused just long enough to allow the disk system to create the snap copy. These volumes could then be mounted to another server for backing up to various storage devices. Snapshots, however, depended on tight hardware and software compatibility which was often problematic, inducing errors that were difficult to track and resolve. In addition, the vendors needed to support various versions of SQL Server, Microsoft applications.

Exchange, Windows® Server, and myriad other

Microsoft developed VSS (Volume Shadow Copy Service) as a common framework to resolve these issues. Available in Windows Server 2003, software and hardware vendors now have a common interface model for generating snapshots. The VSS framework specifies how three distinct components should interact. The three different components are the VSS requestor, writer, and provider. The requestor is the backup software, such as the Backup Exec Agent. The writer is the application software such as SQL Server or Exchange Server that pause to allow the snapshots to be taken. The provider is the specific hardware/software combination that generates the snapshot volume, in this case, the IBM System Storage™ DS Hardware Provider.

The Importance of Exchange VSS Solutions

Businesses have grown to rely on access to their Microsoft Exchange servers to address the increasing demands of mobile computing, global business and electronic commerce. They depend on Exchange e-mail, group scheduling, and calendars for critical business communication and key business processes. E-mail also supports vital applications needed for functions such as workflow, collaboration, and knowledge management. According to Microsoft, nearly 45 percent of business-critical information is housed in email and e-mail-attached documents.

Cost of Downtime

When a critical system like an Exchange server goes down, data, productivity, and money may be lost. For a typical business that has 500 active users on an Exchange server, if access to that server is lost for two hours the company may experience a productivity loss of as much as 1000 employee hours, which can equate to tens of thousands of dollars. That does not consider other losses, such as missed communications from partners, damaged customer relations, or simply lost deals.

Target Environment

The IBM System Storage™ DS6000 and DS8000 series storage arrays target medium to large-size businesses seeking enterprise level reliability, availability, and serviceability (RAS), combined with support of advanced copy features such as FlashCopy environment, it is not uncommon to have multiple DS6000 and DS8000 arrays deployed in a complimentary fashion. The DS8000 series is designed to scale to the needs or the largest enterprise data centers.

, and Metro/Global Mirror®. In a large

Customers deploying these arrays for Exchange-based solutions will typically have installations that range from several servers hosting a thousand or more users on a DS6000 at a single site, to fully-loaded DS8000 multi-node arrays hosting tens of thousands of users. Usually, the latter types of deployments include geographically dispersed clusters with multi-site data replication enabled.

The current version of Backup Exec 11d for Microsoft Exchange does not include instant recovery capabilities, however future releases may support this functionality.

During lab testing the average recovery time for a single Storage Group with a 50GB database was ~ 20 minutes (vs. ~ 5 minutes for instant recovery). While faster than tape-based recovery methods, these restore times should be considered against RTOs and service level agreements (SLAs) if applicable.

In many cases, production recovery requests are for individual mailboxes, rather than entire databases or storage groups. With the introduction of Backup Exec Granular Recovery Technology, Symantec enables faster RTOs for mailbox or item level restores, which can be restored from VSS backups.

Installing CIM Agent for Windows

The CIM Agent for DS Open (API) is a middleware application that provides a CIM-compliant interface for applications that require it, or can make use of it. Elsewhere you may see this (and other interfaces into the DS Open framework) referred to generically as the DS Open API. The agent code provides a CIM API into the IBM System Storage DS8000 & DS6000.

This section includes an overview of the installation process and instructions for installing and configuring the CIM agent on a Windows 2000 or later operating system. It should be noted that although this solution places the CIM agent on a separate Windows 2003 server, that is not a requirement. The CIM agent can be installed on any server (including the Exchange or Backup Exec servers), as well as on Linux® & AIX® hosts.

Installation Overview for Windows

This section provides an overview of the installation and configuration of the CIM agent on a Windows Server 2003 system. Ensure that you have sufficient knowledge of how to administer a Windows Server 2003 system before you install the CIM agent. Also, you should be familiar with the commands that you use during installation and configuration of the CIM agent. The following list of installation and configuration tasks is in the order in which they should be performed:

1. Before you install the CIM agent for Windows, verify the hardware and

software requirements.

2. If you are managing ESS storage units, you must install the

prerequisite ESS CLI level 2.4.0.236 (or higher) software. The ESS CLI must be installed first because the CIM agent sets the path information in shell scripts for you based on the location of the ESS CLI. The CIM agent installation wizard checks your system for the existence of the ESS CLI, and the wizard displays a warning message if ESS CLI is not installed. For ESS CLI installation instructions, see

the IBM TotalStorage Enterprise Storage Server Command-Line Interfaces User’s Guide. This guide is available at:

http://publibfp.boulder.ibm.com/epubs/pdf/f2bcli04.pdf

Attention: If you are upgrading from a previous version of the CIM

agent, you must upgrade the ESS CLI software to the new required

minimum level of 2.4.0.236.

3. You can choose to install the CIM agent either in graphical mode with

the help of an installation wizard or in unattended mode (also known as silent mode), which involves customizing a response file and issuing a command.

4. Verify the CIM agent Windows installation.

5. Configure the CIM agent for Windows. You may want to revisit the

configuration section in the future as you add, change, or delete CIMOM authentication and storage unit information.

6. Verify the connection to your storage unit.

7. Optionally, remove the CIM agent. You only need to perform this

optional task if you get errors during installation verification or if the CIM agent did not set the environment variables.

Configuring the CIM Agent for Windows

This task configures the CIM agent after it has been successfully installed. This section repeats the instructions in the Post Installation Tasks option that you open from the LaunchPad window.

You can also use the modifyconfig command to change the configuration of

some of the parameters that were configured during installation. You can change the CIM agent port value, protocol (HTTP/HTTPS), and enable or disable the debug option.

Steps:

Perform the following steps to configure the CIM agent:

1. Ping each ESS and DS that the CIM agent will manage by typing the

following command:

a. Open a command prompt window and issue a ping command;

for example:

ping 9.11.111.111

where 9.11.111.111 is and ESS or DS IP address.

b. Check that you can see reply statistics from the IP address.

The following is example output:

Pinging 9.11.111.111 with 32 bytes of data: Reply from

9.11.111.111: bytes=32 time<10ms TTL=255

Reply from 9.11.111.111: bytes=32 time<10ms TTL=255

If you see other messages that indicate that the request has timed out, see your Network Administrator for help on establishing network connectivity before you configure storage units.

2. Configure the CIM agent for each ESS or DS which the CIM agent can access. Change directories into the CIM agent directory; for example: C:\Program Files\IBM\cimagent and type the following

command to start the interactive setdevice tool to identify servers to

the CIMOM:

setdevice

a. For each ESS, type the following command:

Exchange 2003 VSS Backup Solution For IBM Storage DS8000/DS6000 And Symantec Backup Exec 11d

Page 20 David West, David Hartman

>>>addess 9.11.111.111 essuser esspass

where:

• 9.11.111.111 represents the IP address of the ESS.

• essuser represents an ESS storage manager user name.

• esspass represents the password for the user name.

The following is example output:

A provider entry for IP 9.11.111.111 successfully added

b. Type the following command for each ESS configured for Copy

Services or for each DS server the CIM agent will access:

>>> addessserver 9.11.111.111 essuser esspass

9.22.222.222

where:

• 9.11.111.111 represents the IP address of the ESS or DS

server

• essuser represents a user name for the server.

• esspass represents the password for the user name.

• 9.22.222.222 represents the alternate IP address of the

server.

Note: Specifying an alternate IP address is optional. The alternate

IP address is used if a connection cannot be made using the primary IP address. The following is example output:

An essserver entry for IP 9.11.111.111 successfully

added

3. Repeat step for each additional storage unit that you want to

configure.

4. Close the setdevice interactive session by typing exit.

5. Once you have defined all the servers, you must stop and restart the CIMOM to make the CIMOM initialize the information for the servers. Because the CIMOM collects and caches the information from the defined servers at startup time, the starting of the CIMOM might take

a longer period of time the next time you start it.

Perform the following steps to use the Windows Start Menu facility to stop and restart the CIMOM:

a. Stop the CIMOM by selecting Start Æ Programs Æ CIM agent

for IBM DS Open API Æ Stop CIMOM service. A command prompt window opens to track the stoppage of the CIMOM.

Note: You might see an error message pop-up window that is

labeled “

java.exe - Application Error”. You must click OK to

close that window to continue.

If the CIMOM has stopped successfully, the following message is displayed:

The CIM Object Manager for DS Open API service was

stopped successfully. Press any key to close the command prompt window.

b. Restart the CIMOM by selecting Start Æ Programs Æ CIM

agent for IBM DS Open API Æ Start CIMOM service. A

command prompt window opens to track the progress of the CIMOM start process. The restarting of the CIMOM can take a while because it is connecting to the defined servers and is caching that information for future use. If the CIMOM has started successfully, the following message is displayed:

The CIM Object Manager for DS Open API service was

started successfully.

Press any key to close the command prompt window.

6. Use the setuser interactive tool to configure the CIMOM for the users

with authority to use the CIMOM.

Note: The users you configure to use the CIMOM are uniquely

defined to the CIMOM software and have no required relationship to operating system user names, the DS Storage Manager user names, or the Copy Services user names.

Upon installation of the CIM agent, the provided default user name is

“superuser” with a default password of “passw0rd”. The first time that you use the setuser tool, you must use this user name and password

combination. Once you have defined other user names, you can start

the setuser command by specifying other defined CIMOM user

names.

Note: The CIMOM must be running before you can use the setuser

command.

a. Open a Command Prompt window and change directory to the

CIM agent directory; for example:

Page 22 David West, David Hartman

C:\Program Files\IBM\cimagent

b. Type the following command at the command prompt to start

the setuser interactive session to identify users to the CIMOM:

setuser -u superuser -p passw0rd

c. Type the following command in the setuser interactive session

to define new users:

>>>adduser cimuser cimpass

where:

• cimuser represents the new user name that can access the CIM

agent CIMOM

• cimpass represents the password for the new user name that

can access the CIM agent CIMOM

The following is example output:

An entry for user cimuser successfully added where

cimuser is the new user name.

7. Repeat step 6c for each additional user name that you want to configure.

8. You can change the default password for “superuser” by starting the

setuser command and by providing a user name and password. Issue the setuser interactive session command to change the password for the superuser:

>>>chuser superuser newpasswd

where newpasswd is the new password for the superuser. You can also delete the superuser by issuing the following setuser

interactive session command:

>>>rmuser superuser

9. Close the setuser interactive session by typing exit. Note: Unlike the setdevice actions, you are not required to stop and

restart the CIMOM to make the setuser actions take effect.

If you were able to perform all of the configuration tasks successfully, the CIM agent has been successfully installed and configured on your Windows system.

Configuring the CIM Agent to run in Unsecure Mode

Some vendor software might not be capable of communicating with the CIM agent in a secure fashion. You can still use this vendor software by configuring the CIM agent to run with only basic user and password security. Perform the following steps to configure the CIM agent to run in unsecure mode:

1. Using the Windows Start Menu facility, stop the CIMOM by selecting

Start Æ Programs ÆCIM agent for IBM DS Open APIÆStop CIMOM service.

2. Using the Windows Services facility, stop and start the Service

Location Protocol (SLP) service by selecting StartÆ SettingsÆControl Panel. Double-click Administrative Tools and double click Services. In the Name column, right-click Service Location Protocol and select Stop. After the SLP stops, start it again by right-clicking the Service Location Protocol again and select Start. After the SLP starts, close the Services Window and the

Administrative Tools Window.

3. Find the cimom.properties file and edit it with a tool such as

Notepad, setting the properties as shown in the following example:

Port=5989 ServerCommunication=HTTP DigestAuthentication=False

Once the CIMOM starts, it accepts requests over HTTP using basic authentication.

Note: To completely disable security checking, set

“Authorization=False” in the cimom.properties file.

4. Using the Windows Start Menu facility, restart the CIMOM by

selecting StartÆProgramsÆCIM agent for IBM DS Open APIÆStart CIMOM service. The CIMOM registers itself with SLP

using the revised attributes.

5. Close this window by pressing any key when you are prompted by the following display:

The CIM Object Manager service is starting .....

The CIM Object Manager service was started successfully

Press any key to continue ...
