5.4. Creating a Fencing Device
5.4. Creating a Fencing Device The following command creates a stonith device. Some fence devices can fence only a single node, while other devices can fence multiple nodes. The parameters you specify when you create a fencing device depend on what your fencing device supports and requires. Some fence devices can automatically determine what nodes they can fence. You can use the pcmk_host_list parameter when creating a fencing device to specify all of the machines that are controlled by that fencing device. Some fence devices require a mapping of host names to the specifications that the fence device understands. You can map host names with the pcmk_host_map parameter when creating a fencing device. For information on the pcmk_host_list and pcmk_host_map parameters, see Table 5.1, "General Properties of Fencing Devices" . After configuring a fence device, it is imperative that you test the device to ensure that it is working correctly. For information on testing fence devices, see Section 5.12, "Testing a Fence Device" .
