Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.

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 HCL OneDB™ Administrator's Guide.
