SVR_FAIL_ACTION can be used if a CM is connected to the OpenSwitch.
For example, you have two OpenSwitch servers, OSW1 and OSW2. OSW1 detects a failure first, but if it does not have a CM connection, OSW1 cannot handle the failure. If OSW2 has a CM connection, it handles the failure. If OSW1 is a primary server, and OSW2 is a secondary server, and both detect the failure, OSW2 handles the failure only if it has a CM and OSW1 does not.
With OpenSwitch 15.1 and later, if you are using a CM or RCM, you can set SVR_FAIL_ACTION to CUSTOM, MANUAL, CUSTOM_MANUAL, or DEFAULT.
See “SVR_FAIL_ACTION,” in Chapter 6, “Using Mutually-aware OpenSwitch Servers” in the OpenSwitch Administration Guide.
