Event Summary

NDDOWN is an AutoSupport message regarding a node being in an unknown state

  • AutoSupport will open a case with subject: NDDOWN:StorageGRID Notification from XXXXXX(NODE_DOWN-CRITICAL) ERROR
  • One or more StorageGRID nodes appear next to a blue icon NDDOWN (Disconnected – Unknown) in the Grid Manager
  • StorageGRID reports the Unable to communicate with Node alert

Validate

  1. Verify the status of the StorageGRID compute node by
    • Checking the status in the StorageGRID GUI and if it still shows as disconnected
    • SSH to the node. If SSH works, but the host id changed, the node is either in the base-os or pre-grid-environment (PGE)
  2. For StorageGRID Appliances, verify the E-Series controller status
