Best Practices and Frequently Asked Questions
Best Practices
When you create the cluster, the machine you happen to be logged into is automatically added to the 
cluster as the first machine, and also added to the Main_Group. Its machine level settings effectively get 
moved to the cluster level as much as possible. There are no settings at the group level, and the only 
settings left at the machine level are those which do not make sense at the cluster level, and cannot be 
clustered. Examples are IP addresses, featurekeys, etc.
Leave as many settings at the cluster level as possible. If only one machine in the cluster needs a different 
setting, copy that cluster setting to the machine level for that machine.  Do not move that setting. If you 
move a setting which has no factory default (e.g. HAT table, SMTPROUTES table, LDAP server profile, 
etc.), the systems inheriting the cluster settings will have blank tables and will probably not process 
email.
To have that machine re-inherit the cluster setting, manage the CM settings and delete the machine 
setting. You will only know if a machine is overriding the cluster setting when you see this display: 
Settings are defined: 
To inherit settings from a higher level: Delete Settings for this feature at this mode. 
You can also Manage Settings. 
Settings for this feature are also defined at: 
Cluster: xxx
Or this display:
Delete settings from:
Cluster: xxx 
Machine: yyyy.domain.com
