Troubleshooting Cluster Problems

A multi-node vRealize Operations cluster does not behave as expected.

Problem

A multi-node vRealize Operations cluster does not behave as expected because of general problems within the cluster or because of suspected firewall concerns.

The problems might occur because of multiple reasons:

• You may be unable to install or uninstall management packs.
• The node shows as offline in the user interface even though it is online.
• You might face problems with new nodes joining the cluster.

Solution

Login to each vRealize Operations node in the cluster and run the following script: $VMWARE_PYTHON_3_BIN /usr/lib/vmware-casa/bin/Netcheck.py

On each node, you are presented with a list of attempted connections. If a node cannot connect to the required port, it is reported in the list. Ports that do not connect must be investigated.

Note: Only one port is required within the range of 10002-10010 and 20002-20010.
