Troubleshooting Cluster Problems

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

Problem

A multi-node VMware Aria 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 VMware Aria 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.
