• Local administrator credentials for ONTAP.
• NetApp onboard key management (OKM) cluster-wide passphrase if using storage encryption.
• SP/BMC accessability for each controller.
• Stop all clients/host from accessing data on the NetApp system.
• Suspend external backup jobs.
• Necessary tools and equipment for the replacement.
If the system is a NetApp StorageGRID or ONTAP S3 used as FabricPool cloud tier, refer
to the Gracefully shutdown and power up your storage system Resolution Guide
performing this procedure.
If using FlexArray array LUNs, follow the specific vendor storage array documentation for
the shutdown procedure to perform for those systems after performing this procedure.
If using SSDs, refer to
failure and data loss if powered off for more than two months
As a best practice before shutdown, you should:
• Perform additional system health
• Upgrade ONTAP to a recommended release for the system.
• Resolve any
Active IQ Wellness Alerts and
Make note of any faults presently on the system, such as LEDs on the system components.
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. Turn off AutoSupport and indicate how long you expect the system to be off line:
system node autosupport invoke -node * -type all -message "MAINT=8h Power
Maintenance"
3. Identify the SP/BMC address of all nodes:
system service-processor show -node * -fields address
4. Exit the cluster shell:
5. Log into SP/BMC over SSH using the IP address of any of the nodes listed in the output from the
previous step.
If your're using a console/laptop, log into the controller using the same cluster administrator
credentials.
Open an SSH session to every SP/BMC connection so that you can monitor progress.
6. Halt all nodes in the cluster:
system node halt -node * -skip-lif-migration-before-shutdown true -ignore
