SYMPTOMS
The Cluster service does not start if the first cluster node is started when no storage units are turned on. If a storage unit is turned on under these conditions, it is not protected when the bus is rescanned and you cannot access the shared disks.
CAUSE
This problem occurs because the ClusDisk (Clusdisk.sys) Plug and Play code adds the disk signature to the appropriate registry key when a new disk is installed on the computer after the computer starts. If the disk needs to be protected (a clustered disk), ClusDisk does not protect it and input/output (I/O) is not blocked.
RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

The English-language version of this fix should have the following file attributes or later:
Date Time Version Size File name ------------------------------------------------------- 29-Sep-2001 13:52 5.0.2195.4439 72,304 Clusdisk.sys
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.

When two nodes start at the same time, a small computer system interface (SCSI) disk may seem damaged to the computer that lost the SCSI reservation.
On computers that are in the cluster, the cluster disk driver attaches itself to the local device, but not to a SCSI drive:
[ClusDisk] GetDevObj: fileObj = 81DE7EE8, devObj= 81FCE350
[ClusDisk] GetDeviceObject: target devobj = 81FCE350, status = 0
[ClusDisk] GetTargetDevice, Found Device Object = 81fce350
[ClusDisk] ScsiInit: attaching to device \Device\Harddisk0\Partition1
[ClusDisk] GetDevObj: fileObj = 81DE7EE8, devObj= 81FCED70
[ClusDisk] GetDeviceObject: target devobj = 81FCED70, status = 0
[ClusDisk] GetTargetDevice, Found Device Object = 81fced70
[ClusDisk] ScsiInit: attaching to device \Device\Harddisk1\Partition1
ClusDisk detects the SCSI drive as a new disk, but it does not attach itself to the device tree:
[ClusDisk] A new disk device arrived
\??\SCSI#Disk&Ven_Net_App&Prod_VLD&Rev_V1.0#1&2afd7d61&1&
{aee56121-e5d9-439f-b8e8-683d135d696b}18960#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}
After the second node loses the SCSI reservation, it continues to receive read and write requests. The storage port driver returns those requests as "SCSI_RESERVATION_CONFLICT". FtDisk.sys reports the errors as "Lost Delayed-Write Data".
When a Move Group command is initiated from the cluster administrator, the cluster disk driver attaches itself:
[ClusDisk] DeleteSignature: Error opening registry key \REGISTRY\MACHINE\SYSTEM\ControlSet001\Services\ClusDisk\Parameters \AvailableDisks\3273B074> for delete. Status c0000034.
[ClusDisk] GetDevObj: fileObj = 81973588, devObj= 819844B0
[ClusDisk] GetDeviceObject: target devobj = 819844B0, status = 0
[ClusDisk] GetTargetDevice, Found Device Object = 819844b0
[ClusDisk] AttachDevice: Attach to partition 4/1
[ClusDisk] Dismounting Partition \Device\Harddisk4\Partition1.
