9/9/2005 2:32:09 PM    iscsi problem with non-master still mounting the disks.
I have a two server cluster that I just switched from SCSI to iSCSI.  
  
I failed it over to node 2 do update none 1 and when node 1 rebooted, it  
  
also mounted the disks.  
  
So, locally on both servers, I could drill into the files.  
  
This can be good for the File Allocation Tables.  
  
Has anyone seen this?  
  
Is there a known fix?  
  
Node 2 does not seem to have this problem.

hi steven!  
  
have you checked the driveletters that they are the same on both cluster  
  
nodes? have you created a cluster resource for the iscsi disk drives?

Was the cluster service running on both nodes when you could write to the  
  
disks? Or could you just see the disks on both nodes, but only write on one  
  
node?  
  
Microsoft uses the shared nothing model, only one node will control a disk  
  
resource at any given time. Both may see them in explorer or disk manager  
  
though, depending on the driver used.  
  
Cheers,

I am confused by your answer, can you restate for me?

I could write from both machines via the same local drive letters.  
  
Only the cluster master was sharing them out.

The cluster name is tg24.  It consists of two nodes, tg22 and tg23.  
  
When tg23 was the master:  
  
tg22 would show the drive letters, but there were no files listed. (as  
  
expected)  
  
tg23 would show the drive letters and have access to the disks. (as  
  
expected)  
  
The server name tg22 would have no shares. (as expected)  
  
The server names tg23 and tg24 would sow the cluster shares. (as expected)  
  
When tg22 was the master: (this is the problem scenario)  
  
tg22 would show the drive letters and have access to the disks. (as  
  
expected)  
  
tg23 would show the drive letters and have access to the disks. (this is  
  
wrong) !!  
  
The server names tg22 and tg24 would sow the cluster shares. (as expected)  
  
The server name tg23 would have no shares. (as expected)  
  
tg23 should not have had read/write access to the disks, but it did.  
  
The next day, (just after I posted the first message) we began to have file  
  
corruption on the shared disk.  
  
Currently tg22 is off and tg23 is the master.  This will be in place until I  
  
get a clue as to the problem or have time off-hours to do more tests.  
  
The shared disks are an iSCSI RAID array.  It is a Promise 15200.  
  
I did not find any option in the iSCSI device to allow only 1 connection.

Until one or more nodes is clustered, you have to keep only one machine on  
  
at a time. From what you describe below all four are clustered and only one  
  
should have access to the disks at anytime.  What iSCSI initiator are you  
  
using? What iSCSI target are you using? Are they the latest? Are you running  
  
Windows Server 2003, SP1. Does the Promise 15200 have a clustering mode?
