  • AFF A700
  • ONTAP 9
  • NVMe coredump device (X9170A SSD)


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:
