Ingres system files, data, and related files must exist on a cluster disk.

A cluster disk is a disk on a shared bus connected to the cluster nodes, which all the cluster nodes can access (though not at the same time).
Access to Ingres data does not depend on the type of cluster disk system (shared external SCSI, SCSI RAID, or SCSI over Fiber Channel).

The cluster service uses the Physical Disk resource type to manage disks that are on a cluster storage device. Disks must have the same drive letters on all cluster nodes.
To prevent data corruption, only one node at a time can use a cluster disk. Cluster Service normally prevents more than one node from using a disk at the same time. However, there are some circumstances not protected by ordinary cluster safeguards: when you install a new disk, and when you remove a disk from a cluster. For more information, see the Windows 2000 Server documentation.

You use the Generic Service resource to manage Windows 2000 services as cluster resources.
The Ingres High Availability Option for Windows installs the Ingres Service as a Generic Service resource type. You must specify, during setup, the Physical Disk resources that contain the Ingres data and related files as dependencies of the Ingres Service cluster resource.
