DOCUMENT:Q305638 12-AUG-2002 [winnt] TITLE :A Windows NT 4.0 Cluster Disk May Generate Error 3 PRODUCT :Microsoft Windows NT PROD/VER::4.0 SP6,4.0 SP6a OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server, Enterprise Edition versions 4.0 SP6, 4.0 SP6a ------------------------------------------------------------------------------- SYMPTOMS ======== During a Move Group or Failover process in a Windows NT 4.0-based cluster, the following error message may be recorded in the Cluster log: Physical Disk ":" DiskspCheckPath: FindFirstFile for "DRIVELETTER:" failed, error 3. This error message typically occurs when the second cluster of a two-node cluster is brought online if the "Failback for a cluster group(s)" option is set to fail back to that node. Additionally, when you perform a Move Group process, the following error message may be recorded in the Cluster log: Physical Disk ":" SCSI, error reserving disk, error 21. CAUSE ===== The first error message is the result of a regression fix from Windows NT 4.0 Service Pack 6a (SP6a). Under certain conditions, the cluster disk driver (Clusdisk.sys) tries to attach to devices but cannot read the partition table (assuming that they are cluster disks that are reserved by the other node).
