Creating a new core group

A default core group, called DefaultCoreGroup, is created for each cell. This default core group is sufficient in most configurations. However there are some circumstances under which you need to create additional core groups for a cell.

Before you begin

Determine how to segment your existing cell into multiple core groups. Use the following rules as guidelines:

Why and when to perform this task

You might want to add another core group to a cell under the following circumstances:

To create a new core group:

Steps for this task

  1. In the administrative console, click Servers > Core groups > Core group settings > New .
  2. In the Name field, specify a unique name for the new core group. The name can contain alpha and numeric characters, but not the following special characters:
    #  \  /  ,  :  ;  "  *  ?  <  >  |  =  +  &  %  ' 
    The name also cannot begin with a period (.) or a blank space. A blank space does not generate an error. However, leading and trailing blank spaces are automatically deleted from the name.
  3. Add a description of this core group that helps other administrators understand the purpose of this core group.
  4. Click OK and Save to save your changes.
  5. Select Synchronize changes with nodes, and click Save again.

Result

The cell contains another core group.
