- The Client Node Name is normally identified to the Storage Manager when the TSM server connection is first opened.
- The File Space or Object Name Space is Teradata.
- The full directory path to any storage object consists of two distinct components: a hierarchical string of directory names and the actual storage object file name.
The left portion of the directory path is a hierarchical string, called the high level name in Tivoli terms. This portion of the path is user-defined, and can be up to 255 characters, including characters normally used to define conventional directory paths.
For more information, see the description of the DATASETNAME field in the section titled, Parameter Definitions below.
The right portion of the directory path is the storage object file name, or the low level name in Tivoli terms. This portion is a system-generated name for individual file segments in the form of Fnnnn, where nnnn is a four-digit integer with leading zeros. For example, a backup of 9 GB of data with the default segment size of 2 GB creates six storage objects with low-level names of F0000 through F0005.
Storage object name F0000 is reserved as a generation number placeholder by the Teradata Access Module for Tivoli. It contains no data.
In general, there is no need to know specific naming conventions because the TDDSMC utility manages storage objects at the backup image level, and because most conventional TSM tools do not display the contents of the storage file spaces created to manage Teradata backups. However, some TSM commands, such as QUERY CONTENT, display individual storage object names. Therefore, some knowledge of these naming conventions is helpful.
