D.

Remove the drives, install the chassis, and place the drives in the new chassis.

Answers
D.

Remove the drives, install the chassis, and place the drives in the new chassis.

Suggested answer: A

Explanation:

When replacing a failed chassis in a Dell PowerScale Gen6 cluster, it's critical to preserve the data and configuration by maintaining the exact placement of the drive sleds. After powering off the nodes, the engineer should:

Remove Drive Sleds:

Carefully remove each drive sled from the failed chassis.

Label for Identification:

Label each drive sled with its corresponding slot number or unique identifier.

Install New Chassis:

Mount the new chassis in the rack where the failed one was located.

Reinstall Drive Sleds:

Insert the labeled drive sleds into the same slots in the new chassis.

Power On Nodes:

Power on the nodes and verify that they boot correctly and rejoin the cluster.

This procedure ensures that the drives remain in their original configuration, preserving data integrity and cluster settings. There's no need to transfer motherboards or reimage drives, as these actions could disrupt cluster operations and lead to data loss.
