1.1.18. Mover Enhancement

Multiple Movers for one or more HPSS instances can now be configured to run on the same machine.

The -c <alternate var path> flag is added to the Mover entry in the inetd configurati on file to specify

an alternate "/var/hpss" path to be used by the Mover. In addition, the -s flag is added to enabl e

syslog logging for the Mover. This feature is intended for multiple HPSS test systems to share the

same set of Mover machines.

1.2. Retired Features

•HPSS is no longer supported fully on Solaris. HPSS Mover and HPSS clients are still being

supported on Solaris.

•The settapestats utility program is no longer supported. The 6.2 Core Server calculate s tape

volume statistics when it starts.

•STK RAIT PVR is no longer supported.

•LTO PVR is no longer supported on Linux. The SCSI PVR should be used for LTO drives on

Linux.

•Non-DCE Gateway is no longer supported.

•Federated Name Space and Remote Site Policy are not supported in 6.2.

•Mirrored Filesets are no longer supported.

•The terminology of "Non-DCE" Movers is no longer being used. It is now referred to as the

Mover.

•The terminology of "Non-DCE" Client API is no longer being used. It is now referred to as

the Client API.

•The hpss_PVrr utility is no longer supported. The source code for this utility can be found

in /opt/hpss/tools/unsupported.

•The hpss.clean command is no longer supported.

•The HPSS Metadata Backup Tools are no longer supported.

1.3. Deferred Features

XFS is not supported in HPSS 6.2. XFS references have been left in the HPSS documentation to

support the option of re-enabling XFS in future releases.

1.4. HPSS Changes

This section describes the changes made to HPSS 6.2.

1.4.1. Documentation Organ ization Changes

The SSM Guide is now merged with the Management Guide.

1.4.2. Metadata Changes

•Added the AUTHZACL table to maintain security ACLs for HPSS servers and for SSM client

access to SSM.

•Deleted the DISKSPACE table. The disk space allocation maps are now maintained in the
