The user can use the MCs table to create, modify, and delete MCs. The default MC can be modified, but cannot be deleted. The default MC uses dashes ( -------- ) for the symbolic name. 

The MCs table shows the following status information: 

GLYPH<SM590000> Name: The name of the MC. Valid characters for this field are A - Z, 0 - 9, $, @, *, #, and %. The first character of this field cannot be a number. This field is the only field that cannot be modified after it is added. 

GLYPH<SM590000> Secondary Pool: The target pool in the volume duplication. If the cluster does not possess a physical library, this column is not visible and the MI categorizes newly created SGs by using pool 0. 

GLYPH<SM590000> Description: A description of the MC definition. The value in this field must be 1 - 70 characters in length. 

GLYPH<SM590000> Retain Copy Mode: Whether previous copy policy settings on private (non-scratch) logical volume mounts are retained. 

Retain Copy mode prevents the copy modes of a logical volume from being refreshed by an accessing host device if the accessing cluster is not the same cluster that created the volume. When Retain Copy mode is enabled through the MI, previously assigned copy modes are retained and subsequent read or modify access does not refresh, update, or merge copy modes. This enables the original number of copies to be maintained. 

GLYPH<SM590000> Scratch Mount Candidate: Clusters that are listed under Scratch Mount Candidate are selected first for scratch mounts of the volumes that are associated with the MC. If no cluster is displayed, the scratch mount process selects among the available clusters in a random mode.
