Add appliances to the cluster

Prerequisites

  • You can only have up to four appliances in a cluster.
  • Ensure that the cluster is functional and in a healthy state. If any other appliance in the cluster is not operational, you may not be able to add an appliance.
  • Ensure that the appliances you are adding are in an unconfigured, original factory setting state.
  • Obtain the Service Tag of the appliances that you want to add.
  • Ensure that you have a sufficient number of unused IP addresses for each appliance. For each appliance you want to add, have at least four IP addresses for the management network and three IP addresses for the storage network. Work with your network administrator to provision and obtain more IP addresses, if necessary. To review, or add more IP addresses, select the Settings icon, and then select Network IPs in the Networking section.
NOTE:The cluster and appliance you are adding must be running the same PowerStoreOS version before the appliance can be added to the cluster. Clusters on PowerStoreOS 3.0.x and later automatically detect if there is a mismatch between operating system versions and provide the option to synchronize during the Add Appliance wizard.

For clusters on PowerStoreOS 2.x and earlier where the appliance is running a later version of the PowerStoreOS than the cluster, upgrade the cluster before adding the new appliance.

For clusters on 2.x and earlier where the cluster is running a later version of the PowerStoreOS than the appliance, the appliance should be installed in the same rack and use the same switches as the existing cluster, and configured into its own separate cluster. Then, upgrade the operating system of the separate cluster. See KB article 000133192 (PowerStore Manager prevents "Add an appliance to an existing cluster") for more information.

About this task

To add appliances to the cluster:

Steps

  1. Under Hardware, click Add in the Appliances tab.
  2. Follow the prompts in the Add Appliance wizard to select and add the appliances to your cluster.
    NOTE:When this process is running, do not run commands, such as adding external hosts or changing CHAP configurations, which can change the state of the cluster.
    NOTE:Any operations started while the Add Appliance process is running will not run until the Add Appliance operation is complete.
  3. If the PowerStoreOS version of the cluster does not match the PowerStoreOS of the appliance being added, you will be prompted to synchronize software versions before adding the appliance. Click Synchronize to initiate the version synchronization.
    When the synchronization is complete, you will be returned to the Add Appliance wizard. Proceed with the rest of the steps of the wizard.
  4. If necessary, upload and install any thin packages that were not installed on the new appliance. See KB article 000226460 (Previously installed thin packages missing following Add Appliance) for more information.
