9 Maintaining Units 3ware RAID controllers include a number of features in the firmware that help maintain the integrity of your drives, check for errors, repair bad sectors, and rebuild units when drives degrade. In addition, 3ware BIOS Manager (3BM) and 3ware Disk Manager (3DM) provide tools to let you check unit and drive status, and manually start background maintenance tasks. 3DM also lets you review alarms and errors and schedule background maintenance tasks. This section includes the following tasks to help you maintain your units: „ Checking Unit and Drive Status through 3DM „ Reviewing Alarms and Errors „ About Background Tasks „ Scheduling Background Tasks „ Rebuilding Units „ Verifying Units Checking Unit and Drive Status through 3DM The information screens in 3DM let you see both summary and detailed information about your 3ware RAID controller, configured units, and available drives in 3DM. You can quickly see the status of your controller and drives, and drill down to find details about any units or drives that have problems. A status column on the controller, unit, and drive information pages lets you quickly see whether everything is working (OK), performing a task (such as initializing, verifying, or rebuilding), or has a problem (error, degraded, warning). Figure 69 illustrates how you can drill down to get additional detail about units and drives in your system. www.3ware.com 165
