CDE Does Not Work with HACMP

Problem

CDE is not working with HACMP.

Solution

The reason that CDE is not functioning is that in HACMP rotating mode, the IP addresses of the HACMP cluster are "rotated." This causes problems with CDE because CDE is very network dependent and needs to resolve the hostname and IP address of the system.

Some possible solutions follow:

• You cannot use HACMP in rotating mode. You must be in concurrent or on the master in a cascading mode system.
• Also ensure that dtlogin is being started after HACMP and that HACMP has not been stopped since dtlogin was started.
• Assigning a network interface that is NOT part of the HACMP cluster as the primary interface to the machine will enable CDE to function properly.
• If you need to run a GUI interface, and you are unable to change from rotating mode and unable to assign a interface that is not part of the HACMP cluster, you can run XDM instead of CDE.
