• You must always capture the node’s console output to a text file.
This provides you a record of the procedure so that you can troubleshoot any issues that you might
encounter during the replacement process.

• If you are using NetApp Storage Encryption, you must have reset the MSID using the instructions in the
“Returning SEDs to unprotected mode” section of the ONTAP 9 NetApp Encryption Power Guide.

• If you have a SAN system, you must have checked event messages (event log show) for impaired node
SCSI blade.
Each SCSI-blade process should be in quorum with the other nodes in the cluster. Any issues must be
resolved before you proceed with the replacement.
• If you have a MetroCluster configuration, you must have confirmed that the MetroCluster Configuration
State is configured and that the nodes are in an enabled and normal state (metrocluster node show).
Option 1: Most systems
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.
About this task
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;
see the
Administration overview with the CLI.
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
The following AutoSupport message suppresses automatic case creation for two hours: cluster1:*>
system node autosupport invoke -node * -type all -message MAINT=2h
2.
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
