Viewing and Setting Controller Policieswww.3ware.com 123the default of 2 TB, up to 8 individual 2 TB volumes will be created fromthe unit.For example, a 5 TB unit would become 3 volumes; two 2 TB volumesand one 1 TB volume. (After creating as many volumes as possible of thespecified carvesize, any remainder will create a final volume.)3 Verify the creation of the volumes through 3DM 2 or the CLI.In 3DM 2, the number of volumes is shown on the Unit Details page.4 Verify that the volumes appear in the operating system. They will appearas additional drives.Notes: If you are configuring a unit for primary storage and it will begreater than 2 TB, be sure to enable the auto-carve policy beforecreating the unit. When volumes have been created through auto-carving, theycannot be deleted except by deleting the unit. If you create a bootable unit that has multiple volumes, the firstvolume is always used as the boot device. Changing the auto-carve policy does not affect existing units.To set the size of volumes created with auto-carving Using the 3ware CLI, use the command /cx set carvesize to specifythe size for volumesThe size can be between 1024Gb and 2048GbFor more information, see the 3ware 9000 Series Serial ATA RAIDController CLI Guide.Setting the Auto-Rebuild PolicyFor 9550SX controllers, the Auto-Rebuild policy determines how thecontroller firmware will attempt to rebuild degraded units.When Auto-Rebuild is disabled, only spares will be automatically used torebuild degraded units. When Auto-Rebuild is enabled, the firmware willselect drives to use for automatically rebuilding a degraded unit using thefollowing priority order. Smallest usable spare. Smallest usable unconfigured (available) drive. Smallest usable failed drive.
