Ingres system files can exist on either the local disks of each cluster node or on the cluster file system. Ingres data and related files must exist on the shared cluster file system. It is recommend that all system, data, and data related files be stored in the cluster file system.

Access to Ingres data does not depend on the type of cluster file system. The cluster file systems must be configured with either Solstice DiskSuite or the VERITAS Volume Manager.
For instructions on creating a global disk group, see the Sun DiskSuite documentation or the VERITAS Volume Manager documentation.
Register the disk group with the cluster using the Sun Cluster administration command scconf.
Configure the disk group as a SUNW.HAStorage Resource Type. This synchronizes actions between HA storage and Ingres High Availability Option. For more information, see the SUNW.HAStorage(5) man page.
