Setting up ONTAP in an eight-node or four-node MetroCluster configuration

After you boot each node, you are prompted to run the System Setup tool to perform basic node and cluster configuration. After configuring the cluster, you return to the ONTAP CLI to create aggregates and create the MetroCluster configuration.

You must have cabled the MetroCluster configuration.

This task is for eight-node or four-node MetroCluster configurations using native Lenovo storage.

This task must be performed on both clusters in the MetroCluster configuration.

This procedure uses the System Setup tool. If desired, you can use the CLI cluster setup wizard instead.

If you have not already done so, power up each node and let them boot completely.

If the system is in Maintenance mode, issue the halt command to exit Maintenance mode, and then issue the following command from the LOADER prompt: boot_ontap

The output should be similar to the following:

Welcome to the cluster setup wizard.

You can enter the following commands at any time:
  "help" or "?" - if you want to have a question clarified,
  "back" - if you want to change previously answered questions, and
  "exit" or "quit" - if you want to quit the cluster setup wizard.
     Any changes you made before quitting will be saved.

You can return to cluster setup at any time by typing "cluster setup".
To accept a default or omit a question, do not enter a value.

By default, AutoSupport transmission is disabled.
In order for this system to send event messages and periodic reports to Lenovo
Technical Support, Autosupport data transmission needs to be enabled.
To enable this feature, either enter "yes" to the following AutoSupport
question, or enter the CLI command "autosupport modify -support enable"
after cluster creation from the CLI. Please review the Lenovo Privacy
statement at www.lenovo.com/privacy before enabling this feature.

Enabling AutoSupport can significantly speed problem determination
and resolution, should a problem occur on your system.

To enable AutoSupport data transmission, type “yes”.
Leave this field blank to keep data transmission disabled {yes, no} [no]:

To continue with the cluster setup wizard, type "yes" {yes}:
.

Enable the AutoSupport tool by following the directions provided by the system.

Respond to the prompts to configure the node management interface.

The prompts are similar to the following:

Enter the node management interface port: [e0M]:
Enter the node management interface IP address: 10.228.160.229
Enter the node management interface netmask: 225.225.252.0
Enter the node management interface default gateway: 10.228.160.1

Confirm that nodes are configured in high-availability mode: storage failover show -fields mode
If not, you must issue the following command on each node and reboot the node: storage failover modify -mode ha -node localhost
This command configures high availability mode but does not enable storage failover. Storage failover is automatically enabled when the MetroCluster configuration is performed later in the configuration process.

Confirm that you have four ports configured as cluster interconnects: network port show

The following example shows output for cluster_A:

cluster_A::> network port show

If you are creating a two-node switchless cluster (a cluster without cluster interconnect switches), enable the switchless-cluster networking mode:
1. Change to the advanced privilege level: set -privilege advanced
  You can respond y when prompted to continue into advanced mode. The advanced mode prompt appears (*>).
2. Enable switchless-cluster mode: network options switchless-cluster modify -enabled true
3. Return to the admin privilege level: set -privilege admin
Launch the System Setup tool as directed by the information that appears on the system console after the initial boot.
Use the System Setup tool to configure each node and create the cluster, but do not create aggregates.
Note
You create mirrored aggregates in later tasks.

Return to the ONTAP command-line interface and complete the MetroCluster configuration by performing the tasks that follow.
