Issue

After system reboot, the following system error is received:

Health Monitor process nphm: CoredumpMissingAlert[-]) ALERT.

Probable Cause: Coredump device "Coredump" is missing from the system.

Possible Effect: Coredump files cannot be saved.

Corrective Actions:

1. Perform a takeover of this node and bring the node down for maintenance.

2. Verify that a coredump device is securely inserted in the system.

3. Use the "bye" LOADER command to reboot the node then perform a giveback.

Check health alert and command below to verify:
