(un)packems#
The packems package was originally designed to simplify the storage of
small files on tape. In the past, small files were not automatically
packed by our software prior to being written to tape. Therefore, users
had to pack their data manually before their archival. The original
version of packems packed sets of small files into tar balls of a
defined size and archived them. The information on which files are
stored in which tar ball is stored in INDEX.txt files archived next
to the tar balls. Tools to list an retrieved data which were archived by
packems were also created. In total, the packems package consisted of
these tools:
packems: pack & archive data
listems: list archived packed data
unpackems: retrieved packed data from tape and unpack them
Since the new Versity HSM software packs small files automatically, packems is not required anymore in most use cases. However, it is still available as packing tool on Levante.

The archival feature of packems has been removed. It can be still used for packing data.

listems#
not available yet
listems will be re-written after the HSM migration has been finished
and the new software is up and running. Until then, please search your
INDEX.txt files manually. They should all be cached and available
via the tape archive mount point /arch on Levante.
unpackems#
not available yet
unpackems will be re-written after the HSM migration has been
finished and the new software is up and running. Until then, please
search your INDEX.txt files manually. They should all be cached and
available via the tape archive mount point /arch on Levante. After
that, please retrieve your tar balls manually via ATLAS (see the Getting
Started pages for details).
