Pre-shutdown checks for onboard encryption keys

Prior to shutting down the impaired node and checking the status of the onboard encryption keys, you must check the status of the impaired node, disable automatic giveback, and check what version of ONTAP the system is running.

  • 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.

    ONTAP System Administration Reference

  1. Check the status of the impaired node:

    • If the impaired node is at the login prompt, log in as admin.

    • If the impaired node is at the LOADER prompt and is part of HA configuration, log in as admin on the healthy node.

    • If the impaired node is in a standalone configuration and at LOADER prompt, contact Lenovo Support.

  2. 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

    The following AutoSupport message suppresses automatic log creation for two hours: cluster1:*> system node autosupport invoke -node * -type all -message MAINT=2h

  3. If the impaired node is part of an HA configuration, disable automatic giveback from the healthy node: storage failover modify -node local -auto-giveback falsestorage failover modify -node local -auto-giveback-after-panic false
  4. Check the version of ONTAP the system is running using the version -v command:
