Shutting down the nodes

You must shut down the nodes in the chassis prior to moving them to the new chassis.

Before you begin

  • If you have a cluster with more than two nodes, it must be in quorum. If the cluster is not in quorum or a healthy node shows false for eligibility and health, you must correct the issue before shutting down the impaired node.

    System Administration Guide

  1. If AutoSupport is enabled, suppress automatic log creation by invoking an AutoSupport message: system node autosupport invoke -node * -type all -message MAINT=number_of_hours_downh

    Example

    The following AutoSupport message suppresses automatic log creation for two hours: cluster1:*> system node autosupport invoke -node * -type all -message MAINT=2h
  2. Disable the HA pair.
    If your system is running clustered ONTAP with...Then...
    Two nodes in the clustercluster ha modify -configured false storage failover modify -node node0 -enabled false
    More than two nodes in the clusterstorage failover modify -node node0 -enabled false
  3. Halt the node, pressing y when you are prompted to confirm the halt: system node halt -node node_name
    The confirmation message looks like the following:
    Warning: Rebooting or halting node
    "node_name" in an HA-enabled cluster may result in client disruption or data access
    failure. To ensure continuity of service, use the "storage
    failover takeover" command. Are you sure you want to halt node
    "node_name"? {y|n}:

    Attention
    You must perform a clean system shutdown before replacing chassis to avoid losing unwritten data in the nonvolatile memory (NVME).
  4. Halt the second node to avoid a possible quorum error message in an HA pair configuration: system node halt -node second_node_name -ignore-quorum-warnings true
