[Linux-cluster] hwo to build a virtual FC-san environment

[Bai Shuwei]

Pasi and Rafael:
    Thanks first.
    My purpose is to build a SAN environment which can support multipath. I
should use the linux environment. So I think the vmware can meet my
requirement.
    But I know little on multipath, from the redhat document, the HBA,
fabric switch are needed. So I want to use the normal source to
build/emulator the multpath environment.

Best Regards!
