IRAWS is an agent used to backup Windows clients (which Backup Exec calls

remote agents). In Backup Exec, a remote agent (client) has the ability to

perform a client side deduplication which is called Direct Access. This requires

the OST plug-in to be installed on the remote agent and the plug-in .dll to exist

in the \Backup Exec\RAWS directory.

Configuring the ETERNUS CS800 S6

You must configure storage servers and logical storage units on the ETERNUS CS800 S6

remote management console before you configure NetBackup or Backup Exec. See the

following sections to configure the ETERNUS CS800 S6 for OST.

Configuring the ETERNUS CS800 S6 consists of the following major steps. See the

following subsections for detailed instructions for completing each step:

●Configuring OST Authentication

●Configuring Storage Servers

●Configuring Logical Storage Units

●Target IP Mapping

IYou can also use the OST Wizard to configure the ETERNUS CS800 S6 for OST.

Configuring OST Authentication

To authenticate the OST storage servers on a media server, you must create OST user

credentials.

VIf you have upgraded to 2.x Software from a version released prior to 2.0, you

must add new OST credentials to the ETERNUS CS800 to continue using OST.

Shut down the NetBackup or Backup Exec services. Then perform the

procedure below, making sure to use the same username and password that

were used to register the existing OST devices. Finally, start the NetBackup or

Backup Exec services.

To create OST user credentials:

1. Log on to the ETERNUS CS800 S6 remote management console.

2. Navigate to the Configuration > OST > Manage Users page (see Figure 1).

3. Click Add.

4. Specify the Username and New Password that will be used to authenticate the storage

servers on the media server.

IFor username, alphanumeric characters are allowed, as well as underscores (

_ ) and hyphens ( - ). For password, alphanumeric characters are allowed, as

well as the following special: ` ~ ! @ # $ % ^ & * ( ) - _ = + [ { ] }

\ | ; : ' “ , < . > / ?

5. Click Apply.

VIn NetBackup or Backup Exec, add credentials for the storage server, making

sure to use the same OST username and password you entered on the

ETERNUS CS800 S6. For more information, see "Registering the Storage

Configuring Storage Servers

To configure storage servers:

1. Log on to the ETERNUS CS800 S6 remote management console.

2. Navigate to the Configuration > OST > Storage Servers page (see Figure 2).

Figure 2: Storage Servers Page

Use the Storage Server page to perform the following tasks. See the following subsections

for detailed instructions for completing each task:

●"Adding a Storage Server"

●"Editing a Storage Server"

●"Deleting a Storage Server"

IIt is recommended to create a different storage server for each NetBackup or

Backup Exec domain (master server plus associated media servers). This

segregates data so a NetBackup or Backup Exec administrator cannot accidentally

modify or remove backup images belonging to another domain.

2. Under Add Storage Server, enter information about the storage server:

●Name - Enter the name of the storage server.

VCAUTION!

Do not use an underscore ( _ ) in the name of the storage server.

IStorage server names must be unique and not used again on other

ETERNUS CS800 S6 systems. Also, storage server names are case

sensitive on all platforms including Windows.

●Description - (Optional) Enter a brief description of the storage server.

●Max Connections - Enter the maximum number of connections allowed to the

storage server (3 to 65536). The maximum connections indicate the number of

NetBackup or Backup Exec jobs that can connect to the storage server.

IIt is recommended to set this value to 300 so that media servers never run

out of storage server connections.

●Enable Concurrent Optimized Duplication - Select the check box to enable

optimized duplication during OST ingest.

Concurrent Optimized Duplication is disabled by default. If enabled, as data is

written to the storage server, it is simultaneously replicated to the target ETERNUS

CS800 S6. When optimized duplication or Automatic Image Replication subse-

quently occurs, the operation is more efficient because a portion of the required

data has already been replicated to the target storage server.

ITo use Concurrent Optimized Duplication, you must configure the source

ETERNUS CS800 S6 and target ETERNUS CS800 S6 for replication (see

"Replication Channel for OST (NetBackup Only)" on page 63).

IWhen Concurrent Optimized Duplication is enabled, all data on the storage

server is duplicated, not just the specified images.

3. Select the check box for each optimized duplication target you want to duplicate the

storage server to. When the storage server is duplicated, its data will be sent to all

selected targets.

4. Under Logical Storage Unit, enter information about the LSU to add to the new

storage server:

●Available Capacity - (Recommended for best performance) Select this option to

add an LSU that uses the available capacity on the system.

You cannot add an available capacity LSU to a storage server that already contains

an LSU. Also, if you add an available capacity LSU to a storage server, you cannot

add additional LSUs to that same storage server.

Configuring the ETERNUS CS800 S6 NetBackup and Backup Exec OST Guide

16 U41853-J-Z125-5-76

IAfter you add an LSU that uses the Available Capacity option, you cannot

change the LSU to use the Specific Capacity option. Instead, you must

delete the LSU, then add a new LSU and choose the Specific Capacity

option (see "Deleting an LSU" on page 23).

●Specific Capacity - Select this option to specify the physical capacity of the LSU,

and then enter the following information.

●LSU Name - Enter the name of the LSU.

●Physical Capacity - Enter the physical capacity of the LSU (1 to 1048576 GB).

IIt is recommended to set LSUs to maximum size (1048576 GB,

because spanning them on a backup is not possible).

5. (Optional) In the Description box, enter a brief description of the LSU.

6. (Optional) Select the Enable Automatic Image Replication check box to automatically

replicate (duplicate) data on the LSU to a remote LSU on another

ETERNUS CS800 S6.

Automatic Image Replication (AIR) is disabled by default. If enabled, data on an LSU is

automatically replicated to a remote LSU that resides on an ETERNUS CS800 S6 in a

different NetBackup domain. The timing of the duplication, as well as the backup

images that are duplicated, are determined by the storage lifecycle policies (SLPs)

configured in NetBackup.

OST AIR requires NetBackup 7.1.x or higher. For more information, see "Setting Up

Automatic Image Replication" on page 65.

ITo use Automatic Image Replication, you must configure the source ETERNUS

CS800 S6 and target ETERNUS CS800 S6 for replication (see "Replication

Channel for OST (NetBackup Only)" on page 63).

IYou must configure at least one remote user before you can enable Automatic

Image Replication (see "Create a Remote User for OST AIR" on page 67).

7. If Automatic Image Replication is enabled, select the replication target you want to

replicate images to. (You can select only a single target.) When images are replicated,

data will be sent to the selected target.

8. If Automatic Image Replication is enabled, specify the following information:

●Remote Storage Server Name - The name of the remote storage server (on the

target ETERNUS CS800 S6) to replicate data to. The source ETERNUS CS800 S6

and target ETERNUS CS800 S6 must reside in different NetBackup domains.

ITo configure the target ETERNUS CS800 S6, see "Replication Channel for

OST (NetBackup Only)" on page 63.

●Remote LSU Name - The name of the LSU in the remote storage server that will

receive the replicated data.

●Remote User - The OST user credentials to use for authentication on the remote

(target) ETERNUS CS800 S6. The selected remote user must match a local user

on the Configuration > OST > Manage Users page on the target ETERNUS

CS800 S6 (see "Configuring OST Authentication" on page 11).

9. Click Apply.

Editing a Storage Server

To edit a storage server:

1. On the Storage Servers page, select the storage server and click Edit.

2. Enter information about the storage server:

IIf you are editing a storage server, the Name option cannot be changed.

●Description - (Optional) Enter a brief description of the storage server.

●Max Connections - Enter the maximum number of connections allowed to the

storage server (3 to 65536). The maximum connections indicate the number of

NetBackup or Backup Exec jobs that can connect to the storage server.

The maximum number of connections cannot be changed if the storage server has

more than zero currently active connections. The number of active connections is

displayed on the OST page (see Figure 2).

IIt is recommended that this value is set to 300 so that media servers never

run out of storage server connections.

●Enable Concurrent Optimized Duplication - Select the check box to enable

optimized duplication during OST ingest.

Concurrent Optimized Duplication is disabled by default. If enabled, as data is

written to the storage server, it is simultaneously replicated to the target ETERNUS

CS800 S6. When optimized duplication or Automatic Image Replication subse-

quently occurs, the operation is more efficient because a portion of the required

data has already been replicated to the target storage server.

ITo configure the target ETERNUS CS800 S6, see "Replication Channel for

OST (NetBackup Only)" on page 63.

IWhen Concurrent Optimized Duplication is enabled, all data on the storage

server is duplicated, not just the specified images.

3. Select the check box for each optimized duplication target you want to duplicate the

storage server to. When the storage server is duplicated, its data will be sent to all

selected targets.

4. Click Apply.

Deleting a Storage Server

To delete a storage server:

1. On the Storage Servers page, select the storage server and click Delete.

You cannot delete a storage server if it has more than zero currently active connections.

The number of active connections is displayed on the OST page (see Figure 2). Also,

you cannot delete a storage server if it contains LSUs. Before deleting the storage

server, you must first delete any LSUs it contains (see "Deleting an LSU" on page 23).

IYou can select multiple storage servers to delete at once.

2. Click Yes.

I(NetBackup only) In order to remove the storage server from the ETERNUS CS800

S6 remote management console, you must remove the storage unit and disk pool

from NetBackup. After successfully deleting the storage units, disk pools and the

corresponding storage server the connection between NetBackup and the storage

server remains open for a grace period of about ten minutes. After the grace period,

the active connection count drops to zero.

Configuring Logical Storage Units

To configure logical storage units:

1. Log on to the ETERNUS CS800 S6 remote management console.
