Chapter 7. Configuring Your Controller Setting the Auto-Rebuild Policy For 9550SX and 9590SE controllers, the Auto-Rebuild policy determines how the controller firmware will attempt to rebuild degraded units. When Auto-Rebuild is disabled, only spares will be automatically used to rebuild degraded units. When Auto-Rebuild is enabled, the firmware will select drives to use for automatically rebuilding a degraded unit using the following priority order. • Smallest usable spare. • Smallest usable unconfigured (available) drive. • Smallest usable failed drive. Enabling Auto-Rebuild allows you to add a drive to the controller and have it be available for a rebuild, without having to specify it as a spare. (For 9500S controllers, you need to tell the controller to Rescan before the controller will see the drive.) With Auto-Rebuild enabled, if you accidentally disconnect a drive (causing the controller to see it as a failed drive) and then reconnect it, the controller will automatically try to use it again. You can enable or disable the Auto-Rebuild policy through 3DM, 3BM, or the CLI. For how to change this setting through CLI, see 3ware 9000 Series Serial ATA RAID Controller CLI Guide. To enable Auto-Rebuild through 3BM 1 On the main 3BM screen, Tab to Settings and press Enter. 2 On the pop-up menu, select Controller Policies and press Enter. 3 On the Policy Settings page, Tab to the Auto-Rebuild field, press Enter to display the options, select Enable and press Enter again to select it. 4 Tab to OK and press Enter to select it. The policy is enabled immediately. To enable Auto-Rebuild through 3DM 1 Choose Management > Controller Settings from the menu bar in 3DM. 2 In the Other Controller Settings section at the bottom of the screen, select the Enabled option for Auto-Rebuild. The page refreshes, and a message at the top confirms the change you have made. 120 3ware Serial ATA RAID Controller User Guide
