Symptoms

The customer upgraded SRM from 3.6.4 to 3.7.1. There were previous attempts without upgrading the Core Modules first, which resulted in incomplete upgrade processes. Once the Core Modules were upgraded, the full upgrade completed without errors. However, after the upgrade, the Load-Balancer Arbiter failed to start with the following error: INFO -- [2016-06-15 14:41:59 EDT] -- CollectorManagerImpl::getComponentInstance(): Configuring connector Arbiter (LoadBalancer v1.4u2 r56779) with /opt/APG/Collecting/Load-Balancer/Load-Balancer/conf/arbiter.xml...

Cause

The file /opt/APG/Collecting/Load-Balancer/Load-Balancer/data/SUMMARY.abs was missing. This was possibly due to previous unsuccessful upgrade attempts, but the exact cause is not confirmed.

Resolution

Copy the SUMMARY.abs file from the from the collector host to the following directory on the Primary Backend:/opt/APG/Collecting/Load-Balancer/Load-Balancer/dataThen restart the Load-Balancer Arbiter using the following command: Linux: ./manage-modules.sh service restart collector-manager Load-Balancer Windows: manage-modules.cmd service restart collector-manager Load-Balancer
