65. his logging is to ensure that the node that gains control of the quorum disk has access to an up to date version of the cluster configuration database Because the quorum disk plays a crucial role in the oper ation of the cluster the loss of a quorum disk causes the failure of the Cluster Server To prevent this type of fail ure the quorum resource should be set up on a redundant array of hard disk drives in the shared storage subsystem Using the ftdisk Driver Microsoft Cluster Server does not support use of the Windows NT software based fault tolerance driver ftdisk with any of the hard disk drives in the shared stor age subsystem However ftdisk can be used with the internal drives of the cluster nodes Custer RAID Controller Functionality The following subsections describe functional variances of standard and cluster enabled PowerEdge Expandable RAID Controllers operating in a PowerEdge Cluster Rebuild Function Does Not Complete After Reboot or Power Loss If the cluster node is rebooted or power to the node is lost while a PowerEdge Expandable RAID Controller is rebuilding a hard disk drive the RAID controller termi nates the rebuild operation and marks the drive as failed This also occurs if the rebuild is performed from the RAID controller basic input output system BIOS con figuration utility and the user exits the utility before the rebuild completes This occurs with all versions of the PowerEdge Expandable
