Configure a Direct-Attached Library with Similar Drive Types

Before You Begin

To configure a direct-attached library with similar drive types

1. Display the Library and Drive Configuration window.
2. Detect the devices. Use Detection or Exhaustive Detection as required.

Note that the Library and Drive Configuration window displays a master drive pool (with a drive pool and the associated drives) for the library.

3. Locate the library that you want to configure.

If the library was never configured, the library status is displayed as not configured.

If you want to modify library properties, right-click the library and select Properties.

From the Library Properties window, you can change the following properties:

  • Alias: Allows you to specify a descriptive name for the library. This name is displayed in the CommCell Browser for the library. We recommend that you give each library a descriptive name for easier system administration.
  • Door Check Seconds: This interval, expressed in seconds, determines how frequently the system checks to see whether the library door is open. If the door is open during a check, the system conducts a full inventory of the library after the door is closed. This way, if media were manually inserted or removed from the library while the door was open, the inventory is updated. This value is editable only before the library is configured.

When you are satisfied with your changes, click OK.

4. Configure the library as described in Configure Devices.

The status of the drive pools and their constituent drives changes to configured.

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.  

Configure a Direct-Attached Library with Mixed Drive Types

Before You Begin

This feature requires a Feature License to be available in the CommServe® Server.

Review general license requirements included in License Administration. Also, View All Licenses provides step-by-step instructions on how to view the license information.

To configure a library with mixed drive types

1. Display the Library and Drive Configuration window.
2. Detect the devices as described in Detect Devices.

NOTES

  • Do not perform an exhaustive detection.

If the library supports SCSI 3 drive identification, the system automatically detects the devices and displays them with detection status detect success, in the Library and Drive Configuration window.

Note that the Library and Drive Configuration window displays a master drive pool (with a drive pool and the associated drives) for each of the drive types in the library.

 

  If the library does not support SCSI 3 drive identification, the system detects the Library with Empty Drive Slots and the drives as StndAln Library.

 

  Map the drives to the appropriate drive slots, by dragging the standalone drives and dropping them on the appropriate drives.

NOTES

Physically verify the drives and the appropriate drive slot numbers before performing this operation 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.  
3. Right-click the library and open the Library Properties window.

Disable the option to Automatically create storage policy for new DataPaths.

4. Configure the library as described in Configure Devices.

If this Discover Media Options dialog box appears during the configuration process, click No.

  The status of the library changes to configured 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.

 

5. Optionally, we recommend that you rename the Master Pools and Drive Pools with appropriate names, based on the drive type. This will help you to easily identify them later.  
  To rename a Master Pool, right-click the MasterPool from the Data Path tab and then click Properties. Type the new name and click OK to save.
  To rename a Drive Pool, right-click the DrivePool from the Data Path tab and then click Properties. Type the new name and click OK to save.
6. The changed names are reflected in the Library and Drive Configuration window.

Exit the Library and Drive Configuration window. To exit, click the Start menu and then click Exit.

7. From the CommCell Console, define the barcode patterns associated with the storage and cleaning media for each drive type.

We highly recommend the usage of a specific barcode pattern for the media associated with each of the drive type in the library. This will help you to easily manage and administer the media in the library. (See Managing Barcodes in a Library for more information.)

8. Create new scratch media pools for the media associated with the various drive types.

We recommend that you use appropriate names based on the drive type for each of the scratch media pools.

Select the appropriate media type from the Default Media Type list.

9. Associate the appropriate barcode pattern in each of these scratch media pools.
10. Create new cleaning media pools for the cleaning media associated with the various drive types.

We recommend that you use appropriate names based on the drive type for each of the cleaning media pools.

Select the appropriate media type from the Default Media Type list.

11. Associate the appropriate barcode pattern in each of these cleaning media pools.
  The sample image shows the scratch and cleaning media pools with appropriate names associated with drives used in this example.
12. Open the Library Properties and enable the Auto-Discovery of Media into default scratch pool option.

Select any one of the media as the Default Media Type.

  • If media is already available in the library, they will be automatically moved into the appropriate scratch pools. If the media is not moved, perform a Full Scan or Discover Media operation.
  • If media is not available in the library, the media will be automatically moved into appropriate scratch pools when you Import Media.

    If you import media that does not match the specified barcode patterns defined for the scratch pools, or is not of the media type associated with the defined scratch pools, the media will be moved to the default scratch pool. If necessary manually move them to the appropriate scratch pools.

13. Create new Storage Policies using the appropriate naming convention as recommended earlier. Associate the Storage Policy Copies to use the appropriate drive pools and scratch pools.

If you have existing storage policies, re-associate them to the appropriate drive pools and scratch pools.

 
 

Post Configuration Considerations

If you are configuring libraries with mixed drive types in a SAN do not enable the options to  automatically configure the data paths in the Storage Policy Copy. (See To automatically configure the data paths in the Storage Policy Copy for more information.)
