News - HSI 6.0.0.p3

Annoucing HSI/HTAR 6.0.0.p3

(03/22/2016)



HSI Version 6.0.0.p3 is now available for HPSS Release 7.5.1 sites. This versions primarily contains internal changes to support new or changed HPSS 7.5 features,  but also adds support for some new/changed features in HSI and HTAR. 

NOTE: HSI and HTAR support is no longer provided directly by Gleicher Enterprises.  
As of March 8 2017, HSI/HTAR support for HPSS sites is transitioning to the National Energy Research Scientific Computing Center (NERSC).  See the support page for more information.

NOTE: HSI 5 is now in maintenance mode, and will only receive bugfixes (no new features) going forward.  Sites are highly encouraged to upgrade to HPSS 7.5.1 and HSI/HTAR Version 6 as soon as possible.


New Features in 6.0.0.p3

New features in this release include:

HSI Major Changes in 6.0.0.p3:
■ Support for PPC Little Endian machines was added

■ User Defined Attribute (UDA) checksums were replaced with End-to-End Data Integrity (E2EDI) checksums.  Existing hashxxx commands continue to work as before, but now use internal HPSS API calls instead of making entries in the userattrs database table.

■ removed obsolete hashconvert command

■ Added initial (minimal) support for HPSS trashcans - added new command trashls 

■ Add new option "-W" to "ls" command to list volume information for disk levels of the hierarchy, similar to the existing "-V" option for tape levels.

■ added ability to temporarily disable HSI puts or gets via the global hsirc


HTAR Major Changes in 6.0.0.p3:
■ GNUTAR-style "exclude" options (--exclude=pattern, --exclude-from=file, ...)  were added for the "create" action.
■ added ability to temporarily disable HSI puts or gets via the global htarrc

■ HTAR code was reformatted for consistency/maintainability
■ added non-HPSS feature to HTAR


HSI Libraries Major Changes in 6.0.0.p3:

■ For kerberos authentication, by default the server now opens a socket for the client to connect to for kerberos protocol.

In previous versions, the client opened a socket for the server to connect to.  The change removes the requirement for client to open firewall port(s) for the kerberos protocol authentication.  The old behavior can continue to be forced for HSI/HTAR clients by setting the environment variable "HSI_KRB_PASSIVE=1"
