ELM may be manually disabled, but this should be done only by experts or consultants. Reasons for disabling ELM include:
rolling upgrades
testing or debugging
When you disable ELM, you must change the HV_USE_ELM variable and then start RMS with a suitable timeout:
In hvenv.local, set HV_USE_ELM=0
See "HV_USE_ELM".
Start RMS with 'hvcm -h <timeout> ...'
The recommended timeout when ELM is disabled is 45 seconds. See the hvcm man page. There is no way to specify the heartbeat timeout when you start RMS from the Cluster Admin GUI.
Point
You can also set HV_USE_ELM=1 in hvenv.local. However, if this setting is in effect when CF is not installed, you will not be able to start RMS. RMS indicates this with a message in the switchlog.
