This section explains how to add new HPE, Supermicro, or Quiver nodes to an existing cluster.
After you connect and power on your new nodes, Qumulo Core discovers any unconfigured nodes automatically and prompts you to add nodes in the Web UI.
If Qumulo Core doesn’t discover any unconfigured nodes, it displays the message No unconfigured nodes found. If you expect to see nodes, contact the Qumulo Care team.
- Qumulo Core requires a short time to update the total available storage.
- Existing nodes retain their numbering.
Sufficient Static IP Addresses: The number of static IP addresses must be equal to or greater than the number of nodes in your cluster. For more information, see IP Failover with Qumulo Core on Qumulo Care.
Same Qumulo Core Version on All Nodes: For information about upgrading Qumulo Core, see Performing a Clean Installation of Qumulo Core and Performing Qumulo Core Upgrades by Using the Web UI on Qumulo Care.
Step 1: Resolve Drive Compatibility Issues
If the version of Qumulo Core on your existing nodes predates the Qumulo-certified drives that you received with your new nodes, you can’t install a lower version of Qumulo Core on your new node and Qumulo Core displays the message Installation failed. Use the cluster logs to identify any incompatible drives.
To receive support for new, Qumulo-certified drives, do one of the following:
Upgrade your existing cluster to the latest version of Qumulo Core and then install the same version of Qumulo Core on your new node. For more information, see Performing Qumulo Core Upgrades by Using the Web UI on Qumulo Care.
Update the Supported Drive List on your new node. For more information, contact the Qumulo Care team.
Step 2: Add Your New Nodes to an Existing Qumulo Cluster
Log in to the Web UI.
Click Cluster > Add Nodes.
On the Add Nodes page, select unconfigured nodes to add to your cluster.
Click Add Selected Nodes to Cluster.
In the Add <N> nodes to cluster <name>? dialog box, click Yes.
If you add one or more node model types, a message reminds you about Qumulo Core adding a new model type to your cluster.
Qumulo Core configures your new nodes and adds them to your cluster.
On the Cluster page, the Web UI shows the banner Successfully added <N> nodes to the cluster and the total available storage.
