5.4 Setting Up Fault Resource Identification and Operator Intervention Request

The fault resource identification is a function that outputs a message to syslogd(1M) and Cluster Admin and a history of failed resources to Resource Fault History if a failure occurs in a resource or node that is registered to a cluster application.

After setting the initial configuration of the resource database, this function enables fault resource identification and operator intervention request. An example of a message displayed by fault resource identification is shown below.

6750 A resource failure occurred.  SysNode:node1RMS userApplication:app0 Resource:apl1

The operator intervention request function displays a query-format message to the operator if a failed resource or a node in which RMS has not been started is found when a cluster application is started. The messages for operator intervention requests are displayed to syslogd(1M) and Cluster Admin.

1421 The userApplication "userApplication" did not start automatically because not all of the nodes
where it can run are online.
Forcing the userApplication online on the SysNode "SysNode" is possible.
Warning: When performing a forced online, confirm that RMS is started on all nodes in the cluster, manually shutdown any nodes where it is not started and then perform it. For a forced online, there is a risk of data corruption due to simultaneous access from several nodes. In order to reduce the risk, nodes where RMS is not started maybe forcibly stopped.
Are you sure wish to force online? (no/yes) Message No: 1001
