configuration
4 logical partitions (created from 2 logical volumes)
2 Logical Volumes (each contains a logical drive)

* Each logical partition appears on two different host
links for the purpose of fault tolerance. Use EonPath
multipath software so that your operating system can
identify alternate paths to the same logical drive.
