Chapter 3: Creating Mirrored Volumes | Creating Mirrored Volumes SAS2 Integrated RAID Solution User Guide 3.2.1 Creating an Integrated Mirroring Volume Disks must have 512-byte blocks and must not have removable media. Integrated mirroring volumes must have two disks, Integrated Mirroring Enhanced volumes can have three-to-ten disks, and Integrated Mirroring + Striping volumes can have an even number of disks ranging from four-to-ten disks. NOTE: LSI strongly recommends that you create global hot spare disks for all mirrored volumes to increase the level of data protection. If a disk in a mirrored volume fails, the Integrated RAID firmware rebuilds it using one of the global hot spares, and the data is safe. If you create two mirrored volumes on an LSI SAS 2 controller, either of the two mirrored volumes can use the global hot spares if a disk fails. Follow these steps to create a two-disk Integrated Mirroring (RAID 1) volume with the SAS2 BIOS CU. The steps begin with the Adapter List window that appears when the SAS2 BIOS CU starts: 1. On the Adapter List window, use the arrow keys to select an LSI SAS adapter, and then press Enter. The Adapter Properties window appears, as the following figure shows.
