Solved: unable to discover external relationships - NetApp Community
Unfortunately, I dont think you can get the constraint name out of the database unless you created it SQL as well: ALTER TABLE M_Employees ADD. DFM keeps insisting that there is a deleted SnapVault relationship that it tries to recreate when I want to get . IIRC (can't access dfm right now.). The backup jobs need to be deleted to remove the snapshots. there is only one option and that's to break the relationships in DFM and clean up the volume manually. . The software can be access here with a NetApp login.
In this example we need to check for the correct volume that relates to the vault copy that needs to be removed from the dataset in DFM. We have 2 lore volumes so we need to be careful which one we manually modify and clear. Click on each of the datasets looking for the volume name on the backup controller.
Delete a relationship
In this example ID: Now we need to get the vault relationships. Right click and Edit the dataset: The screenshots below only show the primary data being cleared. Do the same for Backup and Mirror. In this case I have two controllers, one that is handling snapvaults and one that is handling snapmirrors.
Please note that if you only have a snapvault or a snapmirror then just follow those steps as the other ones will not be relevant. On the snapvault controller run the following: This will help to confirm which snapshot volume you are working with. Any volumes that are still locked by either snapmirror or snapvault will need to have the process disabled.
Copy the full name of the qtree path so you can run the snapvault stop command. On the snapmirror controller you need to break the snapmirror relationship. First you can run the command: Back on the snapmirror controller you will need to edit the snapmirror. To do this run: This will save the file. Run the rdfile command again to ensure that everything looks correct.
The new version of the file should have no reference to the volume you want to remove.

Next you need to remove the snapshots on the volume here also. The common fields must have the same data type. If the primary key field is an AutoNumber field, however, the foreign key field can also be a Number field if the FieldSize property of both fields is the same. When both common fields are Number fields, they must have the same FieldSize property setting.
Create a table relationship by using the Relationships window On the Database Tools tab, in the Relationships group, click Relationships. The Relationships window is not available in an Access web app. To create a relationship in an Access web app, see the steps in Create a relationship. If you have not yet defined any relationships, the Show Table dialog box automatically appears.
If it does not appear, on the Design tab, in the Relationships group, click Show Table. The Show Table dialog box displays all of the tables and queries in the database. To see only tables, click Tables. To see only queries, click Queries. To see both, click Both. Select one or more tables or queries and then click Add. After you have finished adding tables and queries to the Relationships document tab, click Close. Drag a field typically the primary key from one table to the common field the foreign key in the other table.
To drag multiple fields, press the CTRL key, click each field, and then drag them. The Edit Relationships dialog box appears.

Verify that the field names shown are the common fields for the relationship. If a field name is incorrect, click on the field name and select the appropriate field from the list. To enforce referential integrity for this relationship, select the Enforce Referential Integrity check box. For more information about referential integrity, see the section Enforce Referential Integrity. Access draws a relationship line between the two tables.
If you selected the Enforce Referential Integrity check box, the line appears thicker at each end. This means that the Indexed property for these fields should be set to Yes No Duplicates. If both fields have a unique index, Access creates a one-to-one relationship.
This means that the Indexed property for this field should be set to Yes No Duplicates. The field on the many side should not have a unique index. It can have an index, but it must allow duplicates. When one field has a unique index, and the other does not, Access creates a one-to-many relationship.
Top of Page Create a table relationship by using the Field List pane to add a field You can add a field to an existing table that is open in Datasheet view by dragging it from the Field List pane. The Field List pane shows fields available in related tables and also fields available in other tables in the database. When you drag a field from an "other" unrelated table and then complete the Lookup Wizard, a new one-to-many relationship is automatically created between the table in the Field List pane and the table to which you dragged the field.
This relationship, created by Access, does not enforce referential integrity by default. To enforce referential integrity, you must edit the relationship. See the section Edit a relationship for more information.

When you work with a table in Datasheet view, Access displays fields in either of two categories in the Field List pane: Fields available in related tables and Fields available in other tables. The first category lists all of the tables that have a relationship with the table with which you are currently working.
The second category lists all of the tables with which your table does not have a relationship. To add a field to your table, drag the field that you want from the Field List pane to the table in Datasheet view. Drag the field that you want from the Field List pane to the table that is open in Datasheet view. When the insertion line appears, drop the field into position. The Lookup Wizard starts.
