The maintenance utility allows you to configure the storage system and perform maintenance operations. You can launch the maintenance utility in several ways depending on whether your storage system has an SVP:
- With SVP: Log in to Hitachi Device Manager - Storage Navigator, and then select the Maintenance Utility menu.
- Without SVP: Log in to Storage Advisor Embedded, click the Settings icon (top right), and then select Maintenance Utility.
Note:
- The maintenance utility opens on a separate browser tab.
- The browser requirements for the management PC (see Requirements for the Management PC for embedded tools) must be satisfied. When you open the System Monitor window from Storage Advisor Embedded, the browser to be used must be supported by Storage Advisor Embedded.
- Click
in the window to see the help menu for a description of the maintenance utility. - The settings for enlarging and reducing the display might not be reflected in the help window, depending on the type or version of your browser.

- Windows Server 2016 (Server with Desktop Experience) (64 bit)
