SYMPTOMS
The disk signature and the globally unique identifier (GUID)
for a disk may change unexpectedly on Microsoft Windows Server 2003 computers
that have redundant Host Bus Adapters (HBA) configured for a common external
disk. When this problem occurs, programs that depend on this disk signature in
the master boot record (MBR) may fail.
Windows Server 2003 clustering
uses the disk signature and the disk GUID to mount a disk and to bring that
disk online. If the disk signature changes, the disk may fail, and the
following error message may be logged in the system event
log:Event ID: 1034
Source:
ClusDisk
Description: The disk associated with cluster disk resource
DriveLetter could not be found. The expected signature of the disk was
DiskSignature.Additionally, if the disk signature or the disk
GUID changes unexpectedly, drive letters may be reassigned or reordered after
the computer is restarted.
You may also
experience this problem after you remove the HP Secure Path program from a
cluster node that is running Microsoft Windows Server 2003. When you restart
the cluster node, you receive the following Stop error message in the
FTDisk.sys driver:
Stop 0x000000CA
(PNP_DETECTED_FATAL_ERROR)
