Maintenance Overview

Ocient® System Administrators need to perform maintenance for three primary reasons:

• When the Ocient software requires action, such as rebuilding lost or damaged segments
• When firmware or OS software updates are required
• When drive, memory, or system hardware failures occur

The maintenance documentation begins with Ocient software-related maintenance and proceeds to hardware-related maintenance.
