•
Modification of NFS metadata. In support of new authentication mechanisms, elimination of
credential object Id. Change privileged caller principal length from 15 to 255 characters. NFS
is no longer supported. The NFS table contains converted metadata, but will be renamed to
PRE62_NFS to prevent use.
•
Modification of server metadata. In support of new HPSS RPC library, elimination of
authorization service and authentication service information. Addition of request queue size
information and RPC program and version number information. In support of new HPSS
authentication and authorization mechanisms, addition of authentication mechanism
information.
•

•
Modification of site metadata. The conversion utilities do not convert remote site metadata
because remote sites are no longer supported. The conversion will create a new empty SITE
table in DB2.
From 5.1 to 6.2:
•
New AUTHZACL table. This table contains authorized interfaces to servers. The table allows
a server to determine whether a client with a certain authorization mechanism (Unix or
LDAP) may connect to its interface. This table is populated by the hpss_init_server_acls
conversion program.
•
DISKSPACE table is no longer used in 6.2. The core server now uses in-memory disk maps
rather than the metadata in this 5.1 DB2 table.
•

eliminated; Program and Version numbers to the DMG specific configuration have been
added. The metadata is converted by the hpss_51_62_dmg conversion program.

Modification of DMGFILESET table. In support of new HPSS RPC library, elimination of
TCP port and TCP hostname and addition of RPC endpoint information. The metadata is
converted by the hpss_51_62_dmgfileset conversion program.
•

•
Modification of LSPOLICY table. In support of new HPSS RPC library, elimination of group

The metadata is converted by the hpss_51_62_lspolicy conversion program.

program.
