HP Scalable Visualization Array New Features and Release Notes Version 2.1.2

10. Job Launch: Scripts Fail in Directories with Spaces in Names
• Impact
Low.
• Summary
Scripts do not work if executed within directories containing spaces in their names.
• Solution
Change to a directory which does not have a space in its name.
11. Job Launch: EnSight Script Requires Previous ssh Login
• Impact
Low.
• Summary
Before using the sva_ensight82.sh script for the first time, you must ssh to all the
nodes in the cluster, or the script fails.
• Solution
Use ssh to access all the nodes in the cluster before using the script. When you access
each node with ssh, you must do so twice by using each of the two names used by the
nodes for each network. That is, the Administration network uses the base node name,
for example, viz6; the System Interconnect uses the base node name with the ic-
prefix, for example, ic-viz6. To avoid problems, ssh to all the visualization nodes in
the cluster, including the head node, then run the script. You only need to ssh to the
nodes this way one time.
Note that this login step is also needed for the sva_paraview.sh script. Its manpage
documents this requirement.
12. Job Termination: Spurious scancel Warnings
• Impact
Low.
• Summary
Occasionally, jobs end with a warning similar to the following:
scancel: error: Kill job error on job id 431.17: Invalid job id specified
• Solution
This message is harmless and you can ignore it.
The message is an artifact of how job cleanup is done. The cleanup script occasionally
tries to clean parts of the job that didn't start.
13. Environment Variables: path/ld_library_path Conflicts
• Impact
Low.
• Summary
The SVA software adds items to PATH and LD_LIBRARY_PATH environment variables
when you log in or start a shell. If these values are overwritten, the SVA tools will be
unable to start.
• Solution
Instead of replacing a PATH/LD_LIBRARY_PATH, append any new values to existing
values in the environment variables.
