| Greetings NERSC Users,
The upgrade of the Archive or User HPSS system is now complete and the
system is available to users.
In order to access the system, you must remember to:
1. Download a new HPSS client (only for offsite access):
If you use HSI or HTAR from a non-NERSC computational system, you must
download a new client fromhttps://www.nersc.gov/projects/download/hpss/
Failure to download a new client will result in a failed authentication
request. You need a v3.4+ HSI and HTAR client to communicate with HPSS
after the upgrade.
The NERSC computational systems are updated by the Mass Storage Group
and will already have the new HSI and HTAR clients upon completion of
the upgrade.
2. Use a new HPSS authentication token:
If you have an existing $HOME/.netrc file, you should remove any entries
referring to 'machine archive' or 'machine archive.nersc.gov' before
trying to connect to the archive HPSS system.
HSI, HTAR, PFTP and FTP will use a NERSC specific 'authentication token'
when connecting to HPSS. If using a NERSC provided client (HSI, HTAR,
PFTP; or FTP on the NERSC compute platforms), the first time you connect
to the archive HPSS system, you will be prompted for your NIM password
and an authentication token will be generated and stored in
$HOME/.netrc. After completing this step, you will be able to connect
to HPSS without typing a password. The session will look like this:
jhick@davinci:/usr/common/homes/j/jhick> hsi -h archive.nersc.gov
Generating .netrc entry...
jhick@auth2.nersc.gov's password: <ENTER YOUR NIM PASSWORD>
If using an FTP client from off site, or if you wish to use an
alternative method for generating the HPSS token, please
seehttp://www.nersc.gov/nusers/systems/hpss/accounts_passwords.php
3. Note the new location of your home and project directories:
Previous to the upgrade, a user's home directory could be located
anywhere in the HPSS namespace. After the upgrade, home directories
will now be in /home/<first initial of moniker>/<moniker>. For example,
user 'franky' will be in /home/f/franky after logging into Archive HPSS.
We will move your HPSS home directory to this location and create a
symbolic link from your old homedir to this location. If you have
scripts that hardcode or reference the old path, please update them
accordingly.
HPSS project directories will also be moved to /home/projects/<project
dir>. The old project directory (/nersc/projects/<project dir>) will be
a symbolic link to the new location. Please change scripts to reflect
the new location.
4. The syntax HSI uses to specify the HPSS system to connect to has
changed. For connecting to the 'archive' HPSS system, any of the
following invocations may be used:
$ hsi
$ hsi -h archive
$ hsi -h archive.nersc.gov
The following is no longer valid syntax:
$ hsi archive
$ hsi archive.nersc.gov
You will need to update any scripts or automated processes which use the
old syntax.
