Error description

  • Support Engineer: GBH
    Change Team Eng:  EJ
    
    Environment: TSAMP 4.1.0.1
    
    Details:
    Primary node fails and all resources are successfully started
    on standby node. When the original primary node rejoins the
    cluster, all its resource constituents are reported online,
    even though this is not possible. This then triggers global
    offline orders for all resource consituents on all nodes, hence
    causing an outage.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Tivoli System Automation for Multiplatforms
    * users
    ****************************************************************
    * PROBLEM DESCRIPTION:
    * Due to a race condition the resources on a rebooted node might
    * be reported as 'Online', even if those are not. This triggers
    * automation actions to stop the resources on all nodes, which
    * results in an outage of the resources.
    * The problem is caused by improper internal handling that
    * prevents that the resources' internal OpState is set to
    * 'Offline' during node reboot.
    ****************************************************************
    * RECOMMENDATION:
    ****************************************************************
    

Problem conclusion

  • The internal handling of the automation engine has been adjusted
    to address the problem. Now resources on a rebooted node will
    honor the OpState reported by the resource monitor.
