How to Create a Model to Install Comparison

This procedure describes creating a comparison by using the browser interface. You can also create comparisons by using the following command.

• cmp.ds.add – Creates a new comparison.

For a detailed description of this command, see Chapter 5, cmp: CLI Commands for Running Comparisons, in Sun N1 Service Provisioning System 5.1 Command-Line Interface Reference Manual.

Before You Begin

The Remote Agents from each host must be set to use the same locale for Install to Install comparisons to function properly.

To create a new comparison, you must belong to a user group that has Create, Edit, Delete permission on comparisons.

Steps

1. In the navigation menu, click Comparisons.

   The Comparisons page is displayed.

2. Type the name and description of the comparison you want to create and click Create.

   The comparison's Details page is displayed.

3. In the Style of Comparison area, click Model to Install.

4. Select the level of detail that the comparison will use.

   • Directory and File properties. Confirms that both hosts have the same files and directories and that the files and directories are the same sizes.

   • File Contents. Compares the contents of files on both hosts.

     ---

     Note –

     If the component you are using in a comparison includes its own rules about files to ignore, those rules are used in addition to any ignore rules you define for this comparison.

5. Select the scope of the comparison.

   • Host Set. Compares the last known state of the specified host set to its current state.

     1. Select Host Set from the Scope menu.
