To rename a chunk, follow these guidelines for new chunks:
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.
Rename operations fail unless the chunks have the proper permissions. For more information, see the IBM Informix: Administrator's Guide.
