•Monitor cluster logfiles on NodeT if HACMP has been customized to monitor 7133 disk failures.
•Since the 7133 disk is hot pluggable, remove a disk from drawer 1 associated with NodeF's shared volume group.
•The failure of the 7133 disk will be detected in the error log ( errpt
•Verify that all NodeFvg file systems and paging spaces are accessible ( df
•Plug the failed disk back in, then sync the volume group ( syncvg NodeFvg).
•Verify that all NodeFvg file systems and paging spaces are accessible ( df
6.2.5Application Failure
By default, HACMP does not recognize application failures. With some additional configuration, it is possible to “teach” HACMP application failures and trigger events (for more information see 2.6.2.3, “Application Failure” on page 47).
So, the way of testing application failures is strongly dependent on your configuration.
Before you start to do the configuration and the testing application failure notification, analyse your application for possible failures. Then try to reproduce them.
