25 Nov 2019 Change of Access Policy for the tape archive

Due to changed technical specifications for the IBM Spectrum Protect software, we have to change the access policy for the tape archive on SuperMUC-NG.
This will also affect data from SuperMUC, which have already put into the tape archive.

• Permissions to access the data will now be granted to all users of a project i.e., all users in a project group can retrieve data from other users in this project group.
• The previous policy was that only the users who wrote the data into the archive could access it.
• If your project is ‘pr12ab’, you can see the members of this group by
  getent group pr12ab-d
• You have to add the project in the dsmc commands  i.e.
  dsmc q ar “/gpfs/work/p12ab/us12ab5/*“ –se=p12ab
• Please note the difference between the project (“pr12ab”) and the permission group for data (”pr12ab-d”)

27 Nov 2019: HOME directory path will change

You will find all HOME data in the new DSS HOME area, data migration will be performed by LRZ (unless you are specifically notified that you need to perform HOME data migration yourself). For emergency recoveries, the legacy NAS area (pointed to by the HOME_LEGACY variable) will remain available in read-only mode until the end of the year.

Following action is required on your part:  Make necessary adjustments to (job) scripts and configuration data to account for the changes in path names. LRZ strongly recommends using relative path names because this minimizes the required work. 

Examples: 

• Running serial jobs on the Linux-Cluster
• Running parallel jobs on the Linux-Cluster

01 Jan 2020 End of service for NAS systems

NAS paths will be taken offline at the beginning of January, 2020. Please contact the Service Desk for outstanding data migration issues.

NAS PROJECT path is mounted read-only

between 30 Sep 2019 and 31 Dez 2019 

DSS PROJECT now available on HPC systems:

Following action is required on your part:

Migrate data from the legacy NAS area (pointed to by the PROJECT_LEGACY variable) to the new DSS area. LRZ strongly advises to get rid of unneeded data sets, and/or archive data sets to tape.

Step-by-step procedure for migration:

1. On any cluster login node, issue the command
   dssusrinfo all
   This will list paths to accessible containers, as well as quota information etc.
2. Edit your shell profile and set the PROJECT and/or WORK variable to a
   suitable path value based on the above output, typically one of the DSS
   paths with your account name appended to it.
3. Use the cp or rsync or tar command to migrate your data from
   PROJECT_LEGACY to the new storage area.
4. If your scripts use absolute path names instead of the PROJECT or
   WORK variable, they need appropriate updates
