K-432T Chassis Field Replacement Unit

IN THIS ARTICLE 

This article outlines how to swap a chassis on the K-432T platform.

NOTE: Shutting down the node causes a quorum event and puts the cluster into an n-1 state. When you finish the chassis replacement process and power on the new chassis, another event occurs when the node rejoins the quorum.

PROCESS

  1. Power down the node and unplug all cables from it.

  2. Loosen the black thumbscrews and remove your node from the rack.
    NOTE: We strongly recommend getting help from a colleague.
  3. Install the three diskless chassis into the node one by one.

  5. Move the 12 HDDs in each drawer and rear 6 NVMe drives from the existing chassis to the new chassis, ensuring that you install the drives into the same slots.

  8. If the current IPMI settings are set statically (not through DHCP), you must reapply them to each node in the cluster.

RESOLUTION

You can now swap a chassis on the K-432T platform.
