You have missed a critical step! Windows uses an NTFS or FAT filesystem so you have likely formatted your shared LUN with one of these 2. However, these filesystems are NOT cluster aware. So if you want to have a shared LUN where you can read and write files from 2 or more blades, you must format the LUN with a cluster aware filesystem. For example Sanbolic Melio FS is a cluster aware filesystem but there are many many more which you can research and choose from. There may even be a free one available.
So the important thing to remember here is that the system is doing it's job correctly, but the filesystem in your case is causing the problem and will eventually corrupt your data. Whenever 2 or more servers need to read/write to the same disk space (LUN) then you must have a cluster aware filesystem installed on this virtual drive.
I hope this helps,
I second Richard on this. The filesystem on your VD has to be cluster-aware so we need to know which cluster-aware filesystem you format it with. I am a bit skeptic over NTFS not being a cluster-aware filesystem cause in my knowledge it is a cluster-aware filesystem while FAT isn't, let me confirm and get back to you on this. Meanwhile is it possible for you to send me your configurations via email? I have not experienced any such problem yet in this regard however I can test this and send you the considerations and changes required.

Please remember that the shared lun function allows two systems to share the same volume but purely on a hardware level. you will still need to have the OS to be aware that this functionality. (windows clustering services provides this in windows).
Still i am not through with shared LUN in multiple servers. please do the needfull & suggest which is the cluster aware file system for windows 2003 server.
pls suggest freeware or trial cluster aware file system.
