Modifying Partitions

You can modify partition settings any time after a partition is created. For example, you can modify the name, barcode format, cleaning interval, and number of assigned tape drives and slots.

The library automatically takes the partition offline before modifying it and places it back online after it has been modified.

Before deleting a tape drive from a partition, verify that it is unloaded. For information on unloading tape drives, see Unloading Tape Drives.

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

You need administrator privileges to modify partitions.

1. From the Setup menu, select Partitions.

   The Setup - Partitions screen displays.

2. Select a partition to modify and click Modify.

   The Modify Partition - Name screen displays, where Partition Name is the name of the selected partition. The current settings of the partition appear in the Current Settings column.

3. Modify any of the following settings:
   • Partition name — Type a new partition name in the Name text box.

   • NOTE: Partition names are limited to 12 lower-case alphanumeric characters and underscores (_).

   • Number of slots — Type the number of cartridge slots you want to assign to the partition in the Number of Slots text box.
   • Media barcode reporting format — Select a new barcode reporting format from the Set Media Barcode Format drop-down list. The supported formats are:
     • Standard (default) — Five to 16 characters total, including a barcode number and optional two-character media ID. If a media ID is included, the label must have a five to 14 character barcode number followed by a media ID; for example, “XXXXXXXXXXXXXXL4”. If a media ID is not included, the label must have a five to 16 character barcode number; for example, “XXXXX” or “XXXXXXXXXXXXXXXX”. Only the barcode number is reported to the host.
     • Standard Six — Six character barcode number with or without a two-character media ID; for example, “XXXXXXL4” or ”XXXXXX”. Only the six character barcode number is reported to the host.
     • Plus Six — Six character barcode number followed by a two-character media ID; for example, “XXXXXXL4”. The six character barcode and media ID are reported to the host.
     • Extended — Five to 16 characters total, including a barcode number and optional two-character media ID. All characters are reported to the host, regardless of the barcode label having a media ID or not. If a media ID is included, the label must have a five to 14 character barcode followed by a media ID; for example, “XXXXXXXXXXXXXXL4”. If a media ID is not included, the label must have a five to 16 character barcode number; for example, “XXXXX” or “XXXXXXXXXXXXXXXX”.
     • Media ID Last — Five to 14 character barcode number followed by a two-character media ID, for example, “XXXXXXXXXXXXXXL4”. The media ID is reported to the host last, as in “XXXXXXXXXXXXXXL4”.
     • Media ID First — Five to 14 character barcode number followed by a two-character media ID, for example, “XXXXXXXXXXXXXXL4”. The media ID is reported to the host first, as in “L4XXXXXXXXXXXXXX”.

     NOTE: The library supports barcodes up to 16 characters on tape cartridge labels. However, a 16-character barcode label length may not be printable according to the Code 39 label specifications for the tape cartridge area to which the label is attached. The effective tape cartridge barcode label length, including any media ID, may be limited to a maximum of 12 characters.

     NOTE: Checksum characters are not supported on barcode labels.

   • Library-initiated Cleaning — Select the options for the partition's cleaning slots as follows:
   • • Number of Cleaning Slots — Displays the number of configured cleaning slots. If the number of cleaning slots needs to be modified, you must change the number of cleaning slots in Setup Cleaning Slot Configuration. See Configuring Cleaning Slots.
     • Automatic Cleaning — Select the check box to enable library-initiated automatic cleaning. If host-based cleaning is enabled on the host, clear the check box.
   • Tape drive table — Select the check box for each tape drive you want to assign to the partition in the Select Drives section. Clear the check box for each tape drive you want to delete from the partition.

   • NOTE: Before deleting a tape drive from a partition, verify that it is unloaded. For information on unloading tape drives, see Unloading Tape Drives.

4. Click Apply.

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

   • If Success displays in the Progress Window, the partition was successfully modified. Click Close to close the Progress Window.
   • If Failure displays in the Progress Window, the partition was not modified. Follow the instructions listed in the Progress Window to resolve any issues that occurred during the operation.
