Details

The Media Health column was first introduced in 2.60.

When the library firmware is first loaded onto a library, a library reboot and initialization is required. Media Health determination of “GOOD, DEGRADED, or FAILED” are not filled in at this point, the media health status will remain as “UNKNOWN” until the tape is at some point loaded and is mounted from a drive due to normal use or manually moving the tape via the UI to and from a drive. Also, the other fields on the TAPES screen for “last loaded date” and “last drive” will be blank until the tape is loaded in a drive.

To get the MEDIA HEALTH evaluation fields filled out on the TAPE screen with proper icons and proper health reporting – each tape must be loaded into a drive and dismounted.

This moving is done via the BUI (right clicking on the tape and invoking the “move tape” action) or by normal host mount and dismount of a tape to/from a tape drive.

To move a tape manually do the following (however, it is recommended to allow normal tape movement to populate the media health value since moving tapes via the BUI can lead to the tape application database and the library tape database becoming out of sync requiring a manual re-synchonisation of the library and the application to ensure that the application knows the position of all tape volumes in the library)...

How to move tape cartridges using the browser-based user interface:

1. Log in to the browser-based user interface.
2. If the library is partitioned, make sure that the mail slot is assigned to the correct partition. In the graphical library map, check the partition number that appears alongside the Mailslot label.
3. If the mail slot is not properly assigned, assign the mailslot to the required partition now.
4. In the graphical library map, right-click on the data, cleaning, or diagnostics cartridge that you want to move. A context menu appears.
5. In the context menu, select Move Tape. The Move Tape panel appears at the top of the screen.
6. To automatically bring the library back online at the end of the move, check the Set the Library back Online ... checkbox in the Move Tape panel.
    The library automatically goes offline when you move tapes using the user interface.
7. To close the Move Tape panel without taking the library offline and without moving the tape, press the Cancel button.
8. Otherwise, press the OK button.
    The Move Tape panel displays the properties of the selected tape. In the Source row, the partition number (if applicable), current location (Slot, Drive, or Mailslot), and current address of the selected cartridge are preselected. You may change this selection if desired.
9. In the graphical library map, click on an empty destination cartridge slot, drive, or mail slot.
    In the Destination row of the Move Tape panel, the partition number (if applicable), location (Slot, Drive, or Mailslot), and address of the selected target location are preselected. You may change this selection if desired.
10. To close the Move Tape panel without moving the tape, press the Cancel button.
11. To move the tape and close the Move Tape panel, press the OK button. The Move Tape panel closes. You can monitor the move in the library map and in the library activity log.
12. If you did not check the Set the Library back Online ... checkbox, remember to bring the library back online once you are ready.
