article /var/adm/messages kernel: cdrom: open failed

On some agent server configurations, the following types of log messages may appear whenever the up.time monitoring station attempts to contact the agent:

Jun 25 19:19:20 server1 kernel: cdrom: open failed.
Jun 25 19:24:19 server1 last message repeated 2 times
Jun 25 19:29:31 server1 last message repeated 2 times

This issue is a symptom of potential configuration changes required on the agent server and not an up.time agent problem.

The most likely configuration change required is to filter cdrom devices from the /etc/lvm/lvm.conf file on the agent server.

For example, change:

  • From: filter = [ "a/.*/" ]
  • To: filter = [ "r|/dev/cd.*|", "r|/dev/dvd.*|", "a/.*/" ].

Only port 443 (SSL) is required to be open for communication between up.time and the ESX v3 server you want to add to up.time. All SOAP API calls are done through this port.
