This can be done from the SAN Storage management software .Also while making the LUN make the write policy as write through so that the write will be simultaneous in the cache as well as in the disks.

I am able to mount this, but the file system is not getting refreshed. The files created in one server is not visible in the other until a remount is done. Has anybody faced this?
