Configuring RGOffload Extension Properties

This section lists the extension properties that you can configure for RGOffload. The Tunable entry indicates when you can update the property.

Typically, you use the command line scrgadm -x parameter=value to configure extension properties when you create the RGOffload resource.

continue_to_offload (Boolean)

Specifies whether to continue offloading the remaining resource groups in the rg_to_offload list after an error in offloading a resource group.

This property is used only by the START method.

Default: True

Tunable: Any time

max_offload_retry (integer)

Specifies the number of attempts to offload a resource group during startup if cluster reconfiguration or resource group reconfiguration causes a failure to offload. The interval between successive retries is 10 seconds.

If max_offload_retry is too high, the START method of the RGOffload resource might time out before the maximum offload attempts are completed. To avoid this possibility, use the following formula to calculate max_offload_retry:

max-offload-retry < start-timeout /(num-rg × offload-retry-interval)

The value of the max_offload_retry extension property


The value of the Start_timeout of property the RGOffload resource


The number of resource groups to that are to be offloaded


The interval between successive retries, which is 10 seconds

This property is used only by the START method.

Default: 15

Tunable: Any time

rg_to_offload (string)

Specifies a comma-separated list of resource groups that are to be offloaded on a node when a critical failover resource group starts on that node. This property has no default and must be set.

This list should not contain resource groups that depend upon each other. RGOffload does not check for dependency loops in the list of resource groups that are set in the rg_to_offload extension property.

For example, if resource group RG-B depends in some way on RG-A, do not include both resource groups in rg_to_offload.

Default: None

Tunable: Any time
