If a HDD is in Status Impending- or Predictive-Failure you have to set these Offline before you swap it. This Manual will show how to do this. You also can set a HDD Offline in a attached Expansion-Enclosure (f.e. MD12x0 or MD3060e).

  1. Open the Modular Disk Storage Manager (MDSM).
  2. Connect to the relevant storage. 
  3. Click the Tab Hardware.
  4. Mark the harddrive, which shows the impending-status. If it is done, the harddrive will show a blue border stripe.

  5. Now click again on the harddrive with the right mouse-button and choose in the appearing Dialog Box Advanced and then Fail.

  6. The harddrive will went then in failed-status and will be marked with a white X on a red ground.

  7. Now you can swap the harddrive without any problems.

    Tip: If you use a HotSpare it will start a rebuild.
