      - Types of physical restore
      - Cold, warm, or mixed restores
      - ontape utility syntax: Perform a restore
        Use the -r option to perform a full physical and logical restore of the database server data with ontape. Use the -D option to restore selected storage spaces. Use the -rename option to rename chunks during the restore.

  The HCL® Informix® Enterprise Replication Guide describes the concepts of data replication using Informix Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.

New chunk requirements

To rename a chunk, follow these guidelines for new chunks:

The new chunk does not need to exist
You can install the new chunk later and perform a warm restore of a storage space containing it. If you specify a nonexistent chunk, ontape records the rename information in the chunk reserved pages, but does not restore the data. The renamed (but not restored) chunks have a status of offline, designated by D, in the onstat -d chunk status command output.
New chunks must have the proper permissions.
Rename operations fail unless the chunks have the proper permissions. For more information, see the Informix® Administrator's Guide.
