Guest dcastelino Posted April 23, 2008 Posted April 23, 2008 We have NTFS volume on a common shared storage (SAN) Facts: Windows Server 2003 finds this LUN or Volume thru Microsoft iSCSI software initiator without any problems meaning I can copy data on this volume. Issue: The second Windows Server 2003 does not find this volume or LUN on SAN unless I go to Disk Management and format this volume resulting in destroying the data I copied from the first Windows 2003 box. Is there any way where we can make the second windows 2003 box to see the common storage without formatting this volume. Kindly advise Thanks in anticipation

You should not present a LUN to more than one host, unless you plan on implementing clustering.

But let me be even more direct NEVER present a lun to more than one host It WILL CAUSE DATA CORRUPTION ! sorry to be bold, but I have seen it too many times that people loose valuable production data this way.
