Add appliances to the cluster

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 settings state.
● Obtain the Service Tag of the appliances you want to add.
● Ensure that you have 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.
● You cannot have PowerStore T model and PowerStore X model appliances in the same cluster.
NOTE: The cluster and appliance you are adding must be running the same PowerStore OS version before the appliance
can be added to the cluster. Clusters on PowerStore OS 3.0.x and later automatically detect if there is a mismatch between
OS versions and provide the option to synchronize during the Add Appliance wizard.
For clusters on PowerStore OS 2.x and earlier where the appliance is running a later version of the PowerStore OS than the
cluster, upgrade the cluster prior to adding the new appliance.
For clusters on 2.x and earlier where the cluster is running a later version of the PowerStore OS 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 OS of the separate cluster. Log in to Support and refer to KB article 000133192
(PowerStore Manager prevents "Add an appliance to an existing cluster" operation from succeeding if code version of
appliance to be added does not match...) 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 PowerStore OS version of the cluster does not match the PowerStore OS 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.
