Error Message

"VCS WARNING V-16-1-51140 In a multi-CPU system, configure an adequately high value for the ShutdownTimeout attribute."

This is a warning message and has no immediate impact on the cluster.

The VCS ShutdownTimeout attribute determines whether to treat a system reboot as a fault for service groups running on the system. On many systems, when a reboot occurs, the processes are stopped first, and then the system goes down. When the VCS engine is stopped, service groups that include the failed system in their SystemList attributes are autodisabled. However, if the system goes down within the number of seconds designated in the ShutdownTimeout attribute, service groups previously online on the failed system are treated as faulted and failed over to other nodes in the cluster. On nodes with large number of CPUs/memory, the time taken to shutdown the node may exceed the default value of ShutdownTimeout.

For systems running multiple applications and having multi-CPUs, consider increasing the value of the ShutdownTimeout attribute

If required, the ShutdownTimeout value should be set to greater than the maximum time it takes to shut down the system. This can only be determined by a process of trial and error. 

To check the value of ShutdownTimeout attribute, run the following command:

# hasys -value ShutdownTimeout

The value for ShutdownTimeout can be modifiied using following commands –

# haconf -makerw
# hasys -modify ShutdownTimeout
# haconf -dump –makero

Typically all nodes on the cluster will have the same value.
