Environment

Novell Open Enterprise Server 2 (OES 2) Linux
Novell Open Enterprise Server 11 (OES 11) Linux
Novell DHCP Service

Situation

The DHCP server fails to load and you see the following errors in the dhcpd.log file:

dhcpd: Error: Cannot find dhcpService DN  '<a_DHCP_service_and_context>' with server reference. Please update the LDAP server entry '<a_DHCP_server_and_context>'
dhcpd: Error: Confiruation file errors encountered -- exiting


This error is letting you know that there is a disconnect between a service and a DHCP server.

Resolution

Depending on the cause, there are a few ways to resolve this situation.

Cause: The dhcpService does not exist.
Resolution:
  • Launch iManager
  • Click the DHCP (OES Linux)->Service role (left pane)
  • select "Create Service"
  • Create the dhcp service that matches with the error -- '<a_DHCP_service_and_context>'
  • Restart the dhcp daemon.  The DHCP server should now load.
Cause: The dhcpService ('<a_DHCP_service_and_context>') does exist but is not associated to the dhcpServer ('<a_DHCP_server_and_context>')
Resolution:
  • Launch iManager
  • Click the DHCP (OES Linux)->Service role (left pane)
  • select "View/Modify Service"
  • Select the service in question
  • Select the proper server in the "Select the Server:" drop down box
  • Click "Apply" and then "OK"
  • Restart the dhcp daemon.  The DHCP server should now load.
Cause: There are multiple dhcpServices associated to the dhcpServer that will not start (per iManager or dhcp/dns console) -- and at least one of them should not be.
    Also, at least one of the dhcpServices does not show the problemsome dhcpServer as associated.
Resolution:
  • Launch iManager
  • Click the "View Objects" icon (aka Magnifying Glass) in the top row of icons
  • Click the "Browse" tab (between Tree & Search tabs)
  • Browse down to the problem server
  • Right click the problem server and select "Modify Object"
  • Click the "General" tab
  • Click "dhcpServiceDn" in the "Valued Attributes" box, and select "Edit..."
  • Click the double down arrow icon to display all of the values.
  • Select one of the servers that shouldn't be there and press the delete key.  Repeat this step if there are more than one incorrect dhcpService associated.
  • Click the double uparrow icon (used to be the double down arrow) to close the pull-down box.
  • Click "OK" to save the values and return to the previous screen.
  • Click "Apply" and then "OK
  • Restart the dhcp daemon.  The DHCP server should now load.
