Media

Use the Media Add page to add a contiguous range of virtual tape cartridges to a VTL partition. You can specify the initial location, starting barcode, media type, and media capacity. After the cartridges are created, they are available for backing up data.

Note: It is possible to oversubscribe space on the DXi4700. In this case, the total capacity of all media is more than the capacity of the DXi . For guidance on selecting media quantity and size, see Virtual Media—How Many and What Size? on page 23.

To access the Media Add page, on the Media page, click the Add tab (see Figure 1).

To add virtual tape cartridges to a partition:

1. In the Partition drop-down box, select the partition where the media will be created.

2. Under Add Contiguous Media, enter information about the media:

   Initial Location	The initial location for cartridges after they are created (Storage Slot or I/E Slot). Note: You cannot create more cartridges than the number of available slots in the initial location. For example, if 50 I/E slots are available, you cannot create more than 50 cartridges if the initial location is set to I/E Slot.
   Number of Media	The number of cartridges to create in the partition.
   Starting Barcode	The first barcode number in the cartridge sequence. You can enter any alpha-numeric string for the starting barcode (uppercase letters only). Subsequent barcodes are incremented accordingly. For example, if you enter AA, the cartridges are numbered AA0000, AA0001, AA0002, and so on. If you enter a starting barcode with less than 6 characters, zeroes are appended to the barcode to make it 6 characters long.
   Media Type	The media type of the cartridges. Note: The available media type options are determined by the type of tape drive selected when the partition was created (see Adding a VTL Partition).
   Media Capacity	The capacity of the cartridges. Select an option: Native Size - The capacity is determined by the selected media type. Custom Size - The capacity is a custom value. Enter the custom cartridge capacity in the box. Make sure the value is within the acceptable range displayed next to the box

3. Click Apply.

Use the Media Actions page to perform actions on virtual tape cartridges. You can import, export, and remove cartridges from VTL partitions. You can also configure cartridges to be write protected to prevent access.

To access the Media Actions page, on the Media page, click the Actions tab (see Figure 2).

To perform actions on virtual tape cartridges:

1. In the Partition drop-down box, select the partition that contains the cartridges to work with.

   Note: Select UNASSIGNED to work with cartridges that are not assigned to any partition.

   The table displays the following information for all virtual tape cartridges in the partition:

   Barcode	The barcode number of the cartridge.
   Type	The cartridge type (LTO or SDLT).
   Partition	The partition where the cartridge is located.
   WP	The write protect status of the cartridge (Write Enabled or Write Protected).
   State	The state of the cartridge: State: Scratch - Scratch newly created virtual media or virtual media that has been recycled with no data on it. Virtual - Virtual media with data on it. Virtual, Mounted - Virtual media with data that is mounted in a tape drive. Vaulted - Virtual media with data that has been exported from a partition. Data is still intact on the virtual media. Exported - Virtual media with no data that has been exported from a partition. Media has to be in this state before it can be deleted from the DXi4700. Pool - The type of cartridge pool such as application, cleaning, service, or unknown.
   Used (%)	The percentage of the tape cartridge that is used. Caution: The Used (%) value is not updated while the media is mounted. Because of this, the displayed Used (%) value may be different from the real value for mounted media.
   Capacity	The total capacity of the tape cartridge.

   Additional Information

   • Click a column heading to sort the rows in the table by that column.

   • Click the column heading again to reverse the sort order. Click the Information button [i] next to a cartridge to display detailed information about the cartridge.

2. In the Action drop-down box, select the action to perform:

   Delete	Deletes a cartridge from the *UNASSIGNED partition. The cartridge must be in the exported state.
   Export	Removes a cartridge from the virtual media changer and places it in an exported state. Perform this action if an export cannot be performed from the backup application. The cartridge must be in the vaulted, scratch, or virtual state.
   Recycle	Recycles (erases) a cartridge so it can be reused by the partition.
   Write Protect (WP)	Enables or disables write protection for the cartridge.
   Import Media	Imports cartridges into the currently selected partition. Cartridges that are in the exported or vaulted state can be imported from another partition with the same media type and data deduplication settings.

   After you select an action, the table is updated to show only the cartridges that support the selected action. Select Show All Media in the Action drop-down box to see all cartridges.

3. (Optional) To reduce the number of cartridges displayed in the table, enter a barcode or barcode range in the Barcode Filter box and click Apply Filter.

   Use a hyphen (-) to indicate a range, and use an asterisk (*) to indicate a wildcard. Separate multiple entries with commas, and do not use spaces.

   Example: Enter AAA* to display all cartridge barcodes beginning with AAA. Or enter AAA010-AAA020 to display all barcodes in the specified range. Click the Quick Tip icon [?] for additional examples.
