What is the state of my cluster?
To check the current state of your cluster, use the Cluster Summary page or the Cluster Dashboard page of the ClearPath Forward Fabric Management Platform web-based graphical user interface (also called the FMP Manager user interface). Both pages display information on the node, resource and replication states.
Why can several nodes of my cluster not see each other?
Check the following items:
Verify the Firewall settings.
Make sure the switch supports multicast addresses.
Make sure the connection between your nodes is not broken. Most often this is the result of a badly configured firewall. This also may be the reason for a split brain situation where the cluster is partitioned.
How can I create a report with an analysis of all my cluster nodes?
Use the Fabric Manager to generate a dump on the running node. Then go to the other node and run “usysreport” from a command prompt.
Use the hb_report tool to create a high availability specific report. The tool is used to compile:
Cluster-wide log files
Package states
System information
CIB history
After hb_report analyzed all the relevant log files and created the directory (or archive), check the logs for an uppercase ERROR string. The following files are the most important in the top-level directory:
analysis.txt
Compares files that should be identical on all nodes.
crm_mon.txt
Contains the output of the crm_mon command.
corosync.txt
Contains a copy of the Corosync configuration file.
description.txt
Contains all cluster package versions on your nodes. There is also the sysinfo.txt file which is node specific. It is linked to the top directory.
Node-specific files are stored in a subdirectory with the node's name.
