Purpose

After installing a new Oracle VM Server node, a number of checks are necessary to insure that it is configured properly before attempting to add it to an OVS pool. Completing the following 12 steps will insure that the node is ready to be added and become a participating member of an OVS cluster:

1. Verify that /etc/hosts is formatted correctly
2. Ping the hostname to verify that it returns the assigned IP and not 127.0.0.1
3. Test network connectivity by pinging the default gateway or a known host
4. Verify that two operational dns servers are listed in /etc/resolv.conf
5. Verify forward and reverse dns lookups on all Oracle VM pool hostnames and IPs
6. Confirm that /etc/ntp.conf contains at least 2 operational ntp servers
7. Confirm that the system time and date are correct and the ntpd service is active
8. Clean the node in preparation for cluster service with cleanup.py
9. Confirm that the root repository storage is available on the new node
10. Verify network heartbeat peers and paths
11. Update the new node from ULN
12. Reboot to apply changes and insure the node comes up fully operational

The above steps are shortcuts for experienced system administrators. If there is a problem during the step, additional detailed troubleshooting information is provided in related sections below.

An automated script called VMPInfo is also available that will perform most of the steps and display errors on the system console. The script can be downloaded, installed and run in "healthcheck mode" with the following commands:
