Shutdown the controllers - AFF A900

This procedure is for systems with two node configurations. For more information about graceful shutdown when servicing a cluster, see Gracefully shutdown and power up your storage system Resolution Guide - NetApp Knowledge Base.

Before you begin

  • Make sure you have the necessary permissions and credentials:

    • Local administrator credentials for ONTAP.

    • BMC accessibility for each controller.

  • Make sure you have the necessary tools and equipment for the replacement.

Steps

  1. Log into the cluster through SSH or log in from any node in the cluster using a local console cable and a laptop/console.

  2. Stop all clients/host from accessing data on the NetApp system.

  3. Suspend external backup jobs.

  4. If AutoSupport is enabled, suppress case creation and indicate how long you expect the system to be offline:

    system node autosupport invoke -node * -type all -message "MAINT=2h Replace chassis"

  5. Identify the SP/BMC address of all cluster nodes:

    system service-processor show -node * -fields address

  6. Exit the cluster shell:

    exit

  7. Log in to the SP/BMC of each controller using the IP address identified in the previous step:

    • If you log in from the BMC over SSH, connect using the SP/BMC address (for example, ssh admin@<SP/BMC_address>), then enter the command system console and authenticate.

    • If you are using a local console or laptop connected directly to the controller, log in using the same cluster administrator credentials.

  8. Halt the two nodes located in the impaired chassis:

    system node halt -node <node1>,<node2> -skip-lif-migration-before-shutdown true -ignore-quorum-warnings true -inhibit-takeover true

    Note For clusters using SnapMirror synchronous operating in StrictSync mode: system node halt -node <node1>,<node2> -skip-lif-migration-before-shutdown true -ignore-quorum-warnings true -inhibit-takeover true -ignore-strict-sync-warnings true

  9. Enter y for each controller in the cluster when you see:

    Warning: Are you sure you want to halt node <node_name>? {y|n}:

  10. Wait for each controller to halt and display the LOADER prompt.
