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 utilit y 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 addresse s 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 Ut ilities
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 U tilities

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
5.1 conversion 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
