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 Cluster Administrator.
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 Cluster Administrator exclusively.

Hierarchy of cluster resource components

The cluster components are referred to as resources and are placed together in groups. Groups are the
basic unit of failover between nodes. Resources do not fail over individually, rather they fail over with
the group in which they are contained.
In Figure 57 it is depicted as follows:
