White Papers


Abstract

The recommendations in this White Paper apply only if you have configured a Server Time Protocol (STP) Coordinated Timing Network (CTN) with three or more servers, and have assigned the roles listed below. Recommendations for reassigning STP server roles when any of the assigned role servers has a planned or unplanned outage are documented.The recommendations, if not followed, MAY result in all the servers in the CTN becoming unsynchronized, a condition that results in a sysplex wide outage.NOTE! Some aspects of this information is outdated. You must also review white paper WP102037, http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP102037
