Shutting down the node

To shut down the impaired node, you must determine the status of the node and, if necessary, take over the node so that the healthy node continues to serve data from the impaired node storage.

Steps

  1. If you have a cluster with more than two nodes, check the health and Epsilon from advanced mode: cluster show -epsilon *

    If the cluster is not in quorum or a node that is not the impaired node shows false for eligibility and health, correct the issue before proceeding to the next step.

    If Epsilon resides in the impaired node:

    1. Remove Epsilon from the impaired node: cluster modify -node impaired_node -epsilon false
    2. Assign Epsilon to a healthy node in the cluster: cluster modify -node healthy_node -epsilon true
  2. If the impaired node is part of an HA pair, disable automatic giveback from the console of the healthy node: storage failover modify -node local -auto-giveback false
  3. Take the impaired node to the LOADER prompt:
    If the impaired node is displaying... Then...
    The LOADER prompt Go to the next step.
    Waiting for giveback...

    Press Ctrl-C, and then respond y when prompted.

    System prompt or password prompt Take over or halt the impaired node:
    • For an HA pair, take over the impaired node from the healthy node: storage failover takeover -ofnode impaired_node_name

      When the impaired node shows Waiting for giveback..., press Ctrl-C, and then respond y.

    • For a stand-alone system: system node halt impaired_node_name
  4. If the system is in a dual-chassis HA pair or stand-alone configuration, turn off the power supplies, and then unplug the impaired node's power cords from the power source.
  5. If the system is in a stand-alone configuration, turn off the power supplies, and then unplug the impaired node's power cords from the power source.
