multipath-tools with LVM allows you to have two or more paths to a single LUN and do I/O load balancing.
In my case I want to setup initially two paths just to learn how to set it up. We may change it to be 4 paths to a LUN for certain Linux instances that will support hi usage Oracle 10g DBMS. The test Linux instance we are using already has ECKD with LVM filesystems defined that will not be part of the Linux multipath. The new SAN or SCSI Lun we have connected to this sandbox Linux will be LVM but with multipath (multiple paths configured for access to the Lun). Part of the configuration work is to tell LVM that this Lun(s) will be multipathed which requires the filter statement in /etc/lvm/lvm.conf to be modified to support this. Thanks ...........
