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.

In the past I had an VMWare ESX "Virtual FC-SAN" for the purpose of developing and testing cluster solutions. The way i managed that was, more or less (I cant get access to the documentation right now), using a real SAN LUN in VMWare and offering it to several virtual machines as a RAW device, so the same device could be reachable by all VMs at the same time. I think there was also something to do with the NPIV of the ESX servers, but I can't remember it clearly. The VMs were not aware of the device being on a SAN, but at least it was a way to have the same SCSI device in several VMs at the same time, so you can try things as GFS or shared storage clusters. I'm sorry the only proposal is using VMWare, maybe someone can propose more solutions.
