|Oracle Solaris Cluster Geographic Edition System Administration Guide Oracle Solaris Cluster 4.0|
This section provides information about problems that you might encounter when services are migrated by using Geographic Edition software.
When a loss of communication occurs between a node on which the application is online and the storage device, some application resource groups might not failover gracefully to the nodes from which the storage is accessible. The application resource group might result in a ERROR_STOP_FAILED state.
The Oracle Solaris Cluster infrastructure does not initiate a switchover when I/O errors occur in a volume or its underlying devices. Because no switchover or failover occurs, the device service remains online on this node despite the fact that storage has been rendered inaccessible.
If this problem occurs, restart the application resource group on the correct nodes by using the standard Oracle Solaris Cluster procedures. Refer to Clearing the STOP_FAILED Error Flag on Resources in Oracle Solaris Cluster Data Services Planning and Administration Guide about recovering from the ERROR_STOP_FAILED state and restarting the application.
The Geographic Edition software detects state changes in the application resource group and displays the states in the output of the geoadm status command. For more information about using this command, see Monitoring the Runtime Status of the Geographic Edition Software.
