machine to enable the HPSS 6.2 system to work properly. On several test machines, we had
to open world access to the devices used by the HPSS Core Server and PVL in order for them
to initialize properly.
6.3.14. Verify HPSS 4.5 Conversion Results
•
Prior to running the verification utilities, we recommend that running the DB2 utility
RUNSTATS on each table in every database. This will enable the verification utilities to
run quicker than if RUNSTATS is not used. For example: “
db2 runstats on
table hpss.bitfile and indexes all allow write access
”.
•
Prior to running the verification utilities, set the environment variables
HPSS_PRINCIPAL_SSM and HPSS_KEYTAB_FILE_SERVER back to their HPSS 4.5
values as the verification programs need to authenticate with SFS with the proper user
credentials. For example, at most sites the HPSS_PRINCIPAL_SSM should be hpss_ssm
and the HPSS_KEYTAB_FILE_SERVER should be /krb5/hpss.keytabs. After completing
the verifications, these environment variables should be returned to their HPSS 6.2
values.
There are three utilities provided to verify the correctness of the HPSS 4.5 to 6.2 converted metadata.
They are located under $HPSS_ROOT/convert62/bin.
•
db_convert_size_check
•
db_convert_ns_check
•
db_convert_address_check
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.
Simply executing the verification programs will run them with the recommended or default option.
See the utility's usage for additional options which are available. Perform the following steps for
each root and non-root subsystem:
6.3.14.1. Capture Session Output
Set up a scripting session to capture the verification output.
% script verify.output
6.3.14.2. Run db_convert_size_check
Run the db_convert_size_check script.
% db_convert_size_check -g /.:/encina/sfs/hpss/globalconfig
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 checks that all of the expected tables exist and
checks the number of records in each table against the number of records in the corresponding SFS
metadata file(s). This utility runs quickly and should be run at every site. The default behavior of this
utility is to check all metadata tables. If the “-t” option is specified, the utility will only check the
given table. If the “-m” option is specified, the utility will perform a metadata consistency check to
