Veritas recommends to set the SysDownPolicy attribute for the LPAR service group. If the SysDownPolicy attribute is not set and the managed LPAR on one system goes down (but the physical server and managed LPAR are alive), VCS tries to start the managed LPAR on the other node. If the managed LPAR configuration exists on the other node, it leads to concurrency violation and might corrupt the managed LPAR data.
