load into the new table.
•db_convert_nsobject - This program converts the name server object metadata from the HPSS 4.5 nsobjects SFS file to the HPSS 6.2 DB2 NSOBJECT and NSACL tables by reading records from SFS and performing DB2 loads into the new tables.
•db_convert_nstext - This program converts the name server text metadata from the HPSS 4.5 nstext SFS file to the HPSS 6.2 DB2 NSTEXT table by reading records from SFS and performing a DB2 load into the new table.
•db_convert_storagesegdisk - This program converts the disk storage segment metadata from the HPSS 4.5 storagesegmentdisk SFS file to the HPSS 6.2 DB2 STORAGESEGDISK table by reading records from SFS and performing a DB2 load into the new table.
•db_convert_storagesegtape - This program converts the tape storage segment metadata from the HPSS 4.5 storagesegmenttape SFS file to the HPSS 6.2 DB2 STORAGESEGTAPE and ABSADDR tables by reading records from SFS and performing DB2 loads into the new tables.
HPSS 4.5 to 6.2 Verification Utilities
There are three utilities provided to verify the correctness of the HPSS 4.5 to 6.2 converted metadata.
•db_convert_size_check - The utility db_convert_size_check is provided to verify the existence and size of all the expected DB2 tables following the conversion. This utility verifies that all of the expected tables exist and compares the number of records in each table against the number of records in the corresponding SFS metadata file(s)
•db_convert_ns_check - The db_convert_ns_check utility is provided to perform a field level check of the SFS Name Server metadata against the new Core Server metadata
•db_convert_address_check - The db_convert_address_check utility is provided to take HPSS bitfile descriptors and resolve them to media volume names and addresses at each level in the hierarchy in which the file resides. The utility determines these addresses using both SFS and DB2 metadata and compares the results. Options are available to check a subset of files in the system (such as the first and last 1000 files) or every file in the system
Different degrees of verification may be performed based on the amount of time an HPSS site decides to devote to this task. Verification is highly recommended immediately following the conversion before the 6.2 HPSS servers are started.
6.2.9.3. HPSS 5.1 Upgrade Utilities
The utilities listed in this section apply only to upgrades from HPSS 5.1 to HPSS 6.2.
HPSS 5.1 to 6.2 Metadata Conversion Utilities
Prior to performing the metadata conversion, become familiar with the conversion programs and their output. Detailed information for each of these utilities is located in the sections where the utility is run. See Section 6.3.15: Upgrade from HPSS 5.1 to HPSS 6.2 on page 213 for an example of the
5.1conversion utility output. If the conversion program fails, it will exit with an error. To correct the error and continue with the conversion, see Section 6.4: Metadata Conversion Troubleshooting Procedures on page 227. By running the conversion scripts successfully, a site will ensure that the DB2 database is operational and that basic database settings are correct for the configuration database.
The 5.1 to 6.2 metadata conversion is controlled by a menu driven utility called
