PowerStore: Node enters service mode after replacement due to missing or improperly seated embedded module

Summary: During a node replacement procedure, if the node is inserted into the chassis and turns on without the embedded module that is inserted or properly seated, the node enters service mode. Once in this state, rebooting the operating system, power cycling the node, and even physically reseating the Embedded Module or Node may not clear this condition. ...

Symptoms

During a node replacement procedure, the node enters service mode if it is inserted into the chassis and turns on without the embedded module that is inserted or properly seated.

Cause

On initial power of up a replacement node, the hardware configures the Baseboard Management Controller (BMC) network settings using electrical signals from the Embedded module. If the Embedded module is not present or is not properly seated, the BMC settings are persisted incorrectly leading to failures in the storage software that is required to configure the BMC network settings, resulting in the node entering service mode. 

Resolution

Resolution:
If the cluster version is PowerStore v2.1 or later, perform the following:

  • Check that the peer node is healthy.
  • Shut down the node
  • Pull the node out to fully power it off.
  • Reseat the embedded module.
  • Reinsert the node (to result in a cold powerup).

If the cluster version is before PowerStore 2.1, contact Dell EMC Technical Support for further assistance.
