"This article shows you how to boot from SAS storage (in this case, the IBM System Storage DS3200) using the IBM BladeCenter-H and x86-based BladeCenter HS21 and LS21 servers. (For BladeCenter-E, check the blade compatibility matrix listed below in the Resources section to see if your environment is supported.) You will also see how to enable multipathing in Linux. Multipathing, or multipath I/O, is a fault-tolerance and performance enhancement technique where more than one physical path exists between the CPU and its mass storage devices. Simple examples are a SCSI disk connected to two SCSI controllers on the same computer or a disk connected to two Fibre Channel ports.
