Figure 24 Cluster concepts diagram
Sequence of events for cluster resources
The sequence of events in the diagram includes:
1. Physical disks are combined into RAID arrays and LUNs.
2. LUNS are designated as basic disks, formatted, and assigned a drive letter via Disk Manager.
3. Physical Disk resources are created for each basic disk inside Failover Cluster Management.
4. Directories and folders are created on assigned drives.
5. Cluster components (virtual servers, file shares) are created, organized in groups, and placed
within the folders using Failover Cluster Management exclusively.
Hierarchy of cluster resource components
Figure 24 (page 59) depicts the cluster resource hierarchy as follows:
• Physical Disk resources are placed in a cluster group and relate to the basic disk. When a
Physical Disk resource is created through Failover Cluster Management, the resource should
be inserted into an existing cluster group or a corresponding group should be created for the
resource to reside in.
• File share resources are placed in a group and relate to the actual directory on the drive on
which the share is being created.
