Automatically Creating Partitions

You can automatically create additional partitions any time after the initial configuration of the library. The library must contain at least one unallocated tape drive and one unallocated slot to automatically create a partition. If no unallocated tape drives or slots exist, you must modify or delete partitions to free resources. For information on modifying partitions, see Modifying Partitions. For information on how to delete a partition, see Deleting Partitions.

Automatic partitioning assigns library resources proportionately among the partitions, grouping tape drives according to their interface type (SCSI, FC, or SAS), tape drive vendor, and tape drive media type.

The maximum number of partitions that you can create is equal to the number of drives in the library. On the Automatically Create Partitions screen, you can select the number of partitions to create, from a minimum of one to a maximum that equals the number of tape drives in your library. The default is the number of distinct interface type/vendor/media type combinations of the tape drives that are not currently assigned to a partition. If you choose fewer partitions than the default, but more than one partition, some resources will not be assigned to a partition. If you choose one partition, all available resources will be assigned to the one partition.

When the library automatically creates partitions, it assigns control paths. You can change the control paths at any time. For more information about drive control paths, see About Control Paths.

Before automatically creating partitions, verify that all tape drives are unloaded and that all cartridges are in their appropriate storage slots. For information on unloading tape drives, see Unloading Tape Drives.

NOTE: This operation should not be performed concurrently by multiple administrative users logged in from different locations. You can access the appropriate screens, but you cannot apply changes while another administrative user is performing the same operation.

Users with administrative privileges can create partitions, but users with user privileges cannot.

  1. From the Setup menu, select Partitions.

    If one or more partitions are currently configured, the Setup - Partitions screen appears. If no partitions are configured, the Setup - Partition Creation Mode screen appears.

    NOTE: If no unallocated tape drives or slots exist, the Automatic button does not appear. You must modify or delete partitions to free up resources. For information on modifying or deleting partitions, see Modifying Partitions or Deleting Partitions.

  2. Click Automatic.

    The Automatically Create Partitions screen appears.

  3. Using the Partitions drop-down list, select the number of partitions to create. The
  4. NOTE: By default, the library applies the Standard barcode format to each partition. You can change this setting by modifying the partition after it has been created. For information on modifying partitions, see Modifying Partitions.

  5. Click Apply.

    The Progress Window appears. The Progress Window contains information on the action, elapsed time, and status of the requested operation. Do one of the following:

  1. Save the library configuration.

    For instructions on how to save the library configuration, see Saving the Configuration.
