Controller in service mode

A controller was placed in Service mode.

This problem is usually the result of one of the following:

  • The controller was manually placed in Service mode for diagnostic or recovery reasons at the instruction of a Technical Support Engineer.

  • The controller has lost access to all expansion drive shelves and was automatically placed in Service mode.

Important

  • The volumes that were originally owned by the affected controller have been moved to the alternate controller. These volumes will be automatically redistributed back to the controller that owns them once the controller is placed back online.

  • If write caching on any volume is enabled, it might be temporarily suspended until this issue is corrected and all batteries are fully charged (if batteries are present).

Recovery Steps​

  1. Ensure that you have corrected any problems that may have led to the controller being placed in Service mode.

  2. Place the controller online.

    1. Go to Hardware.

    2. Highlight the controller shown in the Details area.

    3. Select Place Online.

  3. Select Recheck to ensure the problem has been resolved.
