5.1.2.3 Troubleshooting a 3PAR GeoCluster for Windows Resource Failure
The 3PAR GeoCluster for Windows resource, upon which depend disk and application
resources, will perform a series of checks upon being brought online. If any of these checks
fail, it will in turn fail. Whether it is right after being installed and configured for the first
time, during a failover test or for an actual site failure, MSCS will attempt to bring the 3PAR
GeoCluster for Windows online on one to several cluster nodes in turn. Every time it
happens, the decision sequence followed by the resource will be logged in the cluster.log.
In order to find and analyze this event sequence, when browsing the relevant cluster.log
report, search for the following event:
OnlineThread: Error <Windows error code> bringing
resource online.
This event concludes any event sequence leading to a failure to bring the 3PAR GeoCluster
for Windows resource online. The events leading to this outcome should provide an explicit
story of why it happened. Any step of the resource decision matrix, whether successful or
failed, will be sanctioned by a cluster.log event. A list of all known 3PAR GeoCluster for
Windows events is included in chapter 5.3.
In addition, any event with the mention of the 3PAR GeoCluster for Windows resource
name as it shows under Other Resource in Cluster Failover Manager will directly relates to
the resource and give hints as to how it was managed by MSCS central resources, such as
Resource Host Subsystem (RHS) or Resource Control Manager (RCM).

required for certain operations, such as its own version upgrade.
