Chapter 7. Configuring Your Controller To use auto-carving 1 Enable the auto-carving feature. You can do so using 3DM, 3BM, or the 3ware CLI. In 3DM, enable Auto-Carving at the bottom of the Management > Controller Settings page. In 3BM, you enable Auto-Carving on the Settings > Controller Policies page. Figure 51. Auto-Carve policy in 3BM In CLI, use the command tw_cli /cx set autocarve=on. For more information, see the 3ware 9000 Series Serial ATA RAID Controller CLI Guide. 2 Create a new unit or migrate an existing unit to include the drives you want to use. With auto-carving enabled, if the combined capacity of the drives exceeds the carve size, a number of volumes will be created. When the carve size is the default of 2 TB, up to 8 individual 2 TB volumes will be created from the unit. For example, a 5 TB unit would become 3 volumes; two 2 TB volumes and one 1 TB volume. (After creating as many volumes as possible of the specified carve size, 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 appear as additional drives. 122 3ware Serial ATA RAID Controller User Guide
