I've created a new LUN and mapped it to an initiator group which includes two hosts. Each host can see the LUN, however do not see the files added by the other. The volume is formatted to NTFS. The odd things I have noticed are:
I've recreated the LUN twice and received the same results. I'm obviously missing something but I'm not sure what.
Thanks in advance!
Depending on what you're trying to do by having this filesystem available on two hosts at the same time it may or may not be possible.
At the heart of your issue is that NTFS is not a clustered filesystem. This means that it does NOT support being mounted simultaneously on two hosts.
If you want specific suggestions, share some background on what you want to achieve.
