iSCSI drive access

I have an IBM iSCSI DS3300 with dual controllers connected to two IBM x3650 M3's. I created one LUN and assigned it to a group which includes my two 3650's... Host1 and Host2, both 2008R2. On Host1 I initialized the drive and it became available and I am able to use the drive now. Host2 automatically shows the new drive and I can use it. The problem is that what I create on Host1 can not be seen on Host2 and vice versa. Did I miss something in my config?

You have to make sure that you provide access controls to the LUNs (same concept as zoning in the fibre channel world).  

Keep in mind that unless you configure MCS (windows clustering) you cannot share LUNs as Windows 2008 is by default not designed for shared storage and doing such can cause data loss.  In a typical environment you create LUNs per server and do not share them unless you are using clustering.

This will not work. You can't mount block-oriented devices in R/W mode on multiple computers.   (Read-only is OK).
Reason is w/o any special software to detect when a host writes to it, and flush I/O, then the two systems will not detect changes made by the other.
