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

NTFS does not support simultaneous access to the file system. You should not
present a LUN to more than one host, unless you plan on implementing
clustering.

Re: NTFS on a common shared storage (SAN)

I absolutely agree with John T on this. 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.
