Creating disk groups and volumes

Last published : Aug 05, 2026
Use Storage Foundation to create disk groups and dynamic volumes on the cluster storage, which in a campus cluster consists of at least two storage arrays.
Before you create disk groups and volumes, consider the following items:
  • The type of volume configurations that are required
  • The number of LUNs required for the disk group
  • The implications of backup and restore operations on the disk group setup
  • The size of databases and logs which depend on the traffic load
  • The disk groups and number of disks on each site
    Note: For campus clusters, each disk group must contain an equal number of disks on each site.
  • Types of volumes required and location of the plex of each volume in the storage array
    Note: Each volume should be a mirrored volume with one plex of the volume on Site A's storage array and the other plex of the volume on Site B's storage array.
Create two or more dynamic cluster disk groups on the storage - one or more for the application data files and one for the mirrored quorum.
