SCSI Logical Drive Fault Tolerance. This shows the fault tolerance mode of the logical drive. The following values are valid for the Logical Drive Fault Tolerance: other(1) The management agent does not recognize the status. You may need to upgrade your software. none(2) Fault tolerance is not enabled. If a physical drive reports an error, the data cannot be recovered. This is known as RAID 0. mirroring(3) For each physical drive, there is a second physical drive containing identical data. If a drive fails, the data can be retrieved from the mirror drive. dataGuard(4) One of the physical drives is used as a data guard drive and contains the exclusive OR of the data on the remaining drives. If a failure is detected, the data is rebuilt using the data guard information plus information from the other drives. distribDataGuard(5) Distributed Data Guarding, sometimes referred to as RAID 5, is similar to Data Guarding, but instead of storing the parity information on one drive, the information is distributed across all of the drives. If a failure is detected, the data is rebuilt using the data guard information from all the drives. enhancedMirroring(6) This is used when there are more than 2 physical disks. Each `mirrored stripe` is written to a disk and is mirrored to an `adjacent` disk. This is commonly referred to as RAID 1E. If a failure is detected, the data is rebuilt using the data from the mirrored stripes on the other drives.
