5.10.2. Shut down the controllers - DM3010H
This procedure is for 2-node, non-MetroCluster configurations only.
Before you begin
You need:
• Local administrator credentials for ONTAP.
• Lenovo onboard key management (OKM) cluster-wide passphrase if using storage encryption.
• SP/BMC accessibility for each controller.
• Stop all clients/host from accessing data on the Lenovo system.
• Suspend external backup jobs.
• Necessary tools and equipment for the replacement.
As a best practice before shutdown, you should:
• Upgrade ONTAP to a recommended release for the system.
• 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
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-quorum
invoke
-node
exit
*
-type
