   RMU (Remote Management Unit) describing an obstruction or
   motion error.
4. An email was received describing a RAS Ticket with an obstruction
   or motion error.

	Poznámka:
	If at any time during any of these steps, there is any issue, doubt of what is being done, or possible thought of breaking hardware - please contact Dell Technical Support for assistance.

1. Before any of these steps are performed, gather a snapshot from the tape library
   and clear the RAS Tickets.
   1. Use the following link on how-to gather a library snapshot:
      
      Informace o páskové jednotce nebo knihovně PowerVault – Pásková knihovna ML6000: Jak stáhnout snapshot
      
      This might be requested by Dell Technical Support, if a support call is
      initiated.
   2. Clear RAS Tickets:
      1. Web Interface > Tools > All RAS Tickets > go into each RAS Ticket >
         Click Resolve (to each one)
      2. Operator Panel > Tools > All RAS Tickets > go into each RAS Ticket >
         Select Resolve (to each one)
2. Firstly, and, if possible, stop the backups and backup
   software services or processes.
3. If not, then wait until the currently backup(s) finish
   completing before taking any other steps.
4. After the backup job(s) and backup software services
   or processes have been stopped - power down the library.
   1. This can be done through the Display (or LCD) > Operations > Shutdown
   2. Web Interface > Operations > System Shutdown
5. Once the library has been powered down, disconnect the data cables between
   the library and the host(s) or server(s).
   
   Do not remove the network cable from the Library Control Module.
6. While the library is powered down, open the I/E (Import/Export) Station Door(s); and
   then, open the Control Module (CM) and/or any Expansion Module Doors.
   
   See the picture below:
   
   
7. After the doors of the ML6000 Tape Library are opened, check for the following:
   1. Media in the picker tape slot.
   2. Tape(s) or media out-of-place, such as not completely in the tape slot.  Check all
      slots.  Consider tapping each media slot to ensure the slots that have media are
      fully in the slot.
   3. If necessary, remove all media from the library.  This can be difficult to accomplish
      if there is more than just the Control Module involved.
   4. Look for any media or tapes, or objects under the robot / picker.  When the library is powered
      off, the "robot" or picker should be resting at the bottom of the floor of a
      module.
      
      If the robot or picker is not at the bottom of the library, a parking tab might be causing the
      robot from moving down the rails of the library.  See parking tab picture below.
   5. Check for any media that has been ejected from a tape drive that has not been moved
      back to a storage and/or I/E slot.
8. Look for any other foreign objects in the library that might be causing a motion failure.
   Examples of this might be as follows:
   1. Barcode labels
   2. Post Notes
   3. Heavy dust, "dust bunnies", dry wall dust, etc.
   4. If any of the following is found, please remove as deemed necessary when
      dealing with sensitive electronic equipment.
      
      An example of this would be using a can of air to remove heavy dust from the
      library.
9. Make sure that the parking tab, as pictured below, is in an un-parked position, and not causing
   interference or robotic movement.
   
   
10. If this is a new installation, or a new module has been added to an existing ML6000 tape library,
    check for the following:
    1. Check for any packing material.
    2. Raise the robot, and make sure it can move in a level manner.
       
       In newer firmware, there is a RAS ticket for a robot that is unlevel.  If this RAS Ticket, T083 -
       Unlevel Robot Assembly Not Level; then, the robot / picker will need to be re-leveled.
       
       Call Dell Technical Support this RAS Ticket is presented, and it does not seem that it can be resolved.
    3. Confirm that all rails inside the library are connected and secure between each module of the library.
11. Confirm that media or tapes where not introduced where media was taken by the picker to a tape drive. 
    If so, a destination full message (RAS Ticket) might be produced.  Remove the media, or move the media
    to a different and empty storage slot.
12. Once these general troubleshooting steps have been performed, power on the ML6000 Tape Library.
    
    Leave the data cables disconnected from the tape library until the issue is resolved.
13. If the RAS Ticket still occurs or presented, see if the tape library firmware is out-of-revision.
     
14. If the firmware is behind, try to update it using the following link:

If the same or different RAS Ticket(s) is still occurring, please gather a snapshot from the library,
and call Dell Technical Support.
