This patch
enables LVM (logical volume manager) to support disk devices that
can be accessed through more than one data path. For example this
could be storage subsystems that can be connected to more than one
controller or that are integrated into storage area networks
(SANs). Normally these would be seen in Linux as multiple block
devices with identical contents that can be accessed independently.
With the patch applied LVM can spread IO over available paths (load
balancing) or automatically re-route data to remaining paths should
some of the paths fail (failover support). In order to get this
working you will need the original LVM package (currently version
1.0.5) from Sistina at:
http://www.sistina.com/lvm
There you also
find information about what LVM is and how to use it. Then you get
the multipath patch package from this page and proceed as described
in the readme file that is included in the package.
For usage of "Multipathing support" see Linux for zSeries and S/390 Device Drivers and
Installation Commands.
