Join nodes to the cluster using the CLI

When the newly installed controller modules are ready, you can add each one to the cluster by using the cluster setup command.

About this task

  • You must perform this procedure on both nodes.

  • You must join each node one at a time, not concurrently.

Steps

  1. Start the Cluster Setup wizard by using the cluster setup command at the CLI prompt.

    ::> cluster setup

Welcome to the cluster setup wizard....

Use your web browser to complete cluster setup by accessing
https://10.63.11.29

Otherwise, press Enter to complete cluster setup using the
command line interface:
    Note

    For instructions using the GUI-based cluster setup wizard, see Adding nodes to the cluster using System Manager.

  2. Press Enter to use the CLI to complete this task. When prompted to create a new cluster or join an existing one, enter join.

    Do you want to create a new cluster or join an existing cluster? {create, join}:
join

  3. When prompted with the existing cluster interface configuration, press Enter to accept it.

    Existing cluster interface configuration found:

Port    MTU     IP              Netmask
e1a     9000    169.254.87.75   255.255.0.0

Do you want to use this configuration? {yes, no} [yes]:

  4. Follow the prompts to join the existing cluster.

    Step 1 of 3: Join an Existing Cluster
You can type "back", "exit", or "help" at any question.

Enter the name of the cluster you would like to join [cluster1]: cluster1

Joining cluster cluster1

Starting cluster support services ..

This node has joined the cluster cluster1.

Step 2 of 3: Configure Storage Failover (SFO)
You can type "back", "exit", or "help" at any question.

SFO will be enabled when the partner joins the cluster.

Step 3 of 3: Set Up the Node

Cluster setup is now complete.

    The node is automatically renamed to match the name of the cluster.

  5. On the cluster, verify that the node is part of the cluster by using the cluster show command.

    cluster1::> cluster show
Node                  Health  Eligibility
--------------------- ------- ------------
cluster1-1            true    true
cluster1-2            true    true
cluster1-3            true    true
3 entries were displayed.

  6. Repeat step 1 through step 5 for the second newly installed controller module.

    The Cluster Setup wizard differs on the second node in the following ways:

    • It defaults to joining the existing cluster because its partner is already part of a cluster.

    • It automatically enables storage failover on both nodes.

  7. Verify that storage failover is enabled and possible by using the storage failover show command.

    The following output shows that storage failover is enabled and possible on all nodes of the cluster, including the newly added nodes:

    cluster1::> storage failover show
                              Takeover
Node           Partner        Possible State
-------------- -------------- -------- -------------------------------------
cluster1-1     cluster1-2     true     Connected to cluster1-2
cluster1-2     cluster1-1     true     Connected to cluster1-1
cluster1-3     cluster1-4     true     Connected to cluster1-3
cluster1-4     cluster1-3     true     Connected to cluster1-4
4 entries were displayed.
