Automatically Configure Libraries Shared Across a SAN
Manually Configure Libraries Shared Across a SAN
Configure a Library with Mixed Drive Types in SAN
The following procedure describes the steps involved in automatically configuring a library that is shared across a SAN with DDS, in both the clustered and non-clustered environment. This procedure does not apply to NAS-attached libraries. See Configure a Library Shared Across a SAN Environment for step-by-step instructions on configuring NAS-attached libraries.
Before You Begin |
||
Check the following before you configure the library in the SAN environment:
|
||
To automatically configure libraries shared across SAN |
||
1. |
Display
the Library and Drive Configuration window.
In the Select MediaAgents dialog box, select the name of any one MediaAgent that will share the library. |
|
2. |
Detect the devices. Use
Detection or
Exhaustive Detection as required.
If the library supports SCSI 3 drive identification, it is not necessary to perform an exhaustive detection. |
|
The library and all drives are displayed for the MediaAgent that is connected to the SAN in the Library and Drive Configuration window. | ||
For a Solaris MediaAgent in the SAN environment, the operation will
fail to detect devices with SCSI target higher than 15 and/or LUN higher
than 7. In a such a situation additional entries must be added for such
devices in the wa.conf file. For information
on adding these entries see Add Additional Entries
in wa.conf File in the Solaris MediaAgent. For a NetWare MediaAgent, you may see a number of drives in addition to the drives that are actually present. These drives are displayed as empty slots. You can ignore these empty slots and configure the library using the drives that were detected successfully. If any additional drives are visible on any of the MediaAgents due to incorrect zoning you must do one of the following:
|
||
3. | Right-click the library and then click Properties. | |
4. | From the Library Properties dialog box,
select the following option:
Optionally, consider the following options and enable or disable it if necessary:
Click OK. NOTES
|
|
5. | Configure the library as described in Configure Devices. | |
The library is configured and displayed with the
configured, detect success status in the
Library and Drive Configuration window.
The Library tab provides the physical view of the devices (library and drives).
|
||
The Data Paths tab provides a logical view of the data path used to access
the devices - library, master drive pool, drive pool, drive.
|
||
To automatically configure the data paths in the Storage Policy Copy |
||
6. |
Optionally, perform the following steps if you want the system to
automatically create the
alternate data paths in the Storage Policy Copy
that was created during the library configuration. NOTES A data path is the combination of MediaAgent, Library, Drive Pool and Scratch Pool used by the storage policy copy to access the library. When you have several MediaAgents accessing a library, you can create a Storage Policy when you configure the library the first time. For subsequent MediaAgents, you can do the following:
|
|
|
||
|
||
To automatically configure the other MediaAgents that share the library in SAN |
||
7. | Install the library and ensure that the operating system detects the library. (See Driver Configurations for information on how to check this information for various operating systems.) | |
8. | Install the MediaAgent software on all the other computers that will share the library. (See MediaAgent Deployment for information on installing the MediaAgent software.) | |
If you have already installed the MediaAgent software, stop and start the
MediaAgent Services on all the MediaAgents sharing this library. For more information on stopping and starting services, see the following topics: |
||
Open the Library and Drive Configuration window and verify that the libraries
are configured from all the MediaAgents that share the library.

||
The Data Paths tab provides a logical view of the data path used to access the devices - library, master drive pool, drive pool, drive. | ||
Post-Configuration Considerations |
||
After configuring all the libraries, consider disabling the hat the Auto Configure DDS DrivePool and Auto Configure Failover Library Controllers options described in Step 4, if you do not want the system to automatically configure the library whenever a new MediaAgent is installed in the SAN. |
The following procedure describes the steps involved in configuring a library that is shared across a SAN with DDS, in both the clustered and non-clustered environment. This procedure does not apply to NAS-attached libraries. See Manually Configure NAS-attached Libraries Shared Across a SAN for step-by-step instructions on configuring NAS-attached libraries.
Before You Begin |

8. |
Configure the library as described in
Configure Devices.
This will configure the library and the library controllers for the library. If you do not wish to configure the library controllers on one or more of the MediaAgents, you must delete them before configuring the library. To delete, right-click the appropriate library controller and then choose Delete. Click OK in the confirmation prompt that appears. |
|
Post Configuration Considerations |
||
If you subsequently add new MediaAgents with visibility to a configured
library and drives, the system will automatically configure the libraries
and drives in those MediaAgents.
Perform the following steps if you wish to disable the automatic library and drive configuration in such MediaAgents: |
||
From the Library and Drive Configuration window, open the Library Properties dialog box associated with the library you wish to disable automatic configuration. | ||
Disable the following options:

The following procedure explains the steps involved in configuring a NAS-attached library which is shared in the SAN environment by multiple NAS file servers and/or MediaAgents.
Before You Begin |
||
|
||
Configuration Procedure |
||
1. |
You must first configure the library from any one of the MediaAgents
that share the library across a SAN. Use one of the following
procedures to configure the library for the first time:
Once you have configured the library for the first time you can use the following procedure to configure the library from a NAS file server. |
|
2. | Display the Library and Drive Configuration window. | |
3. |
If necessary, select a new MediaAgent that must be used by the File
Server to communicate. To select a new MediaAgent, click the Start button and then click Select MediaAgents. Select the appropriate MediaAgent from the Select MediaAgent dialog box and click OK. |
|
4. | Click the Start button, and then select Detect/Configure Devices. | |
5. |
Select the NDMP Devices and the MediaAgent that will control
the library. Select the Exhaustive Detection option. Click OK. NOTES
|
|
6. |
A prompt appears informing you that the exhaustive detection will unload
all drives and hence may interfere with backup/restore jobs. Click Yes. |
|
7. | Select the File Server from which you wish to detect the library and click OK. | |
8. |
Click Yes to start the device
detection process. NOTES
|
|
9. | When the exhaustive detection process is completed, the log file is displayed. Note the log file contents and click Close to proceed. | |
10. | An Information prompt appears, informing you to right-click the device to continue the configuration. Click OK to proceed | |
11. |
When the Exhaustive Detection is completed, the system displays the
devices in the Library and Drive Configuration window. NOTES
Right-click the library and then click Configure. The Library tab provides the physical view of the devices (library and drives). |
|
The Data Paths tab provides a logical view of the data path used to access the devices - library, master drive pool, drive pool, drive. | ||
12. | Configure the library as described in Configure Devices. | |
13. | If you have configured the library, the status of the library
changes to configured.
If you chose to configure all associated drives, the status of the drives, the master drive pool, and drive pool that contains the drives changes to configured. If you do not need to configure any other libraries, exit now. NOTES
