Appendix C Sun Cluster Support for Oracle RAC Extension Properties

The extension properties that you can set for each Sun Cluster Support for Oracle RAC resource type are listed in the following sections:

You can update some extension properties dynamically. You can update others, however, only when you create or disable a resource. For more information, see How to Modify an Extension Property That Is Tunable Only When a Resource Is Disabled. The Tunable entries indicate when you can update each property.

For information about all system-defined properties, see the r_properties(5) man page and the rg_properties(5) man page.

This property specifies a comma-separated list of logical volumes that the fault monitor of the resource is to monitor. This property is optional. If you do not specify a value for this property, all logical volumes in the device group are to be monitored.

The status of the device group is derived from the statuses of the individual logical volumes that are monitored. If all monitored logical volumes are healthy, the device group is healthy. If any monitored logical volume is faulty, the device group is faulty.

The status of an individual logical volume is obtained by querying the volume's volume manager. If the status of a Solaris Volume Manager for Sun Cluster volume cannot be determined from a query, the fault monitor performs file input/output (I/O) operations to determine the status.

If a device group is discovered to be faulty, monitoring of the resource that represents the group is stopped and the resource is put into the disabled state.

For mirrored disks, if one submirror is faulty, the device group is still considered to be healthy.
