Model Upgrade

Overview

To improve the system performance and to increase the maximum number of installable drives, this function upgrades the storage system from a lower model to a higher model.

This function provides the following features:

  • User data is taken over without any changes.

  • All the configuration information for the storage system including licenses (for Advanced Copy and for port expansion) is taken over.

    Note that the unique information of the storage system (such as the serial number, the model name, and the product ID) is not included if the storage system is replaced due to a model upgrade.

  • After a model upgrade is performed, the maximum parameters (such as the number of DEs, drives, LUNs, hosts, and copy sessions) of the higher model apply.
