Dell PowerStore X model Software Upgrade Guide

Adding an Appliance to a Cluster

When adding an appliance to a cluster, the cluster and appliance must be on the same PowerStoreOS version. Clusters on PowerStoreOS 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 PowerStoreOS 2.x and earlier where the appliance is running a later version of the PowerStoreOS 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 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 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.

For clusters and appliances on 3.0.x or later, the unconfigured appliance PowerStoreOS version is automatically updated to match the PowerStoreOS version of the cluster during the reinitialization step when the appliance is added to the cluster.

For more information about adding appliances, refer to the PowerStore Manager Online Help and the PowerStore Installation and Service Guide for your model.
