Because EVSs and secure EVSs inherit many of their settings from the cluster’s global context, when configuring name services, you must specify if you want to change the global context or the individual context.

For example, on the NIS/LDAP Configuration page or the EVS Details page, the current security context displayed as follows.


The EVS security context can be any of the following:

  • Global Configuration, which indicates that the current security context is the global context.
  • Inherits Global Configuration, which indicates that the EVS is a regular EVS (not a secure EVS), and it uses the security context settings defined in the global security context.
  • Individual Configuration, which indicates that the current security context is an individual context that has individually specified settings.

On the Name Services and NIS/LDAP Configuration pages, click change to switch the current context between an individual context for a particular secure EVS and the global context.

If you make changes that affect:

  • The global context, those changes apply to all EVSs that have security context settings set to Inherits Global Configuration.
  • An individual context, those changes apply only to the currently selected EVS.

On the EVS Details page, click change to switch the context used by the EVS:

  • If an individual context is being used, you can change the EVS to use the global context, removing the individual security context and changing the secure EVS into a regular EVS.
  • If the global context is being used, you can change the EVS to use an individual context (creating a secure EVS).
