Shutting down the nodes

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

Before you begin

Steps

  1. If AutoSupport is enabled, suppress automatic case 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 case 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 cluster cluster ha modify -configured falsestorage failover modify -node node0 -enabled false
    More than two nodes in the cluster storage 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. Where applicable, 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
