General System Administration

HP Partitioning

Chapter 5

• New variables in /etc/rc.config.d/wlm file to support new communications

daemon, wlmcomd

• New example configurations for transient groups and for vPar and nPar

management in /opt/wlm/examples/wlmconf

• Passive mode now supports auditing

Impact

WLM A.02.02 includes the following impacts:

• Enhanced Wizard and new GUI simplify configuring WLM

• nPar resizing opens new possibilities in partition management

• PSET-based groups with no active SLOs now get 0 CPUs, allowing CPUs to be used

elsewhere

• With the new cntl_smooth keyword, you are advised to transition away from the

smooth and expsmooth utilities

• WLM scripts that use perl now require perl to be in /opt/perl/bin/ instead of

/usr/contrib/bin/

• If you have modified /etc/rc.config.d/wlm, you should merge the new file

(/opt/wlm/newconfig/etc/rc.config.d/wlm) with your /etc/rc.config.d/wlm

file

Compatibility

• WLM scripts that use perl now require perl to be in /opt/perl/bin/ instead of

/usr/contrib/bin/

• If you have modified /etc/rc.config.d/wlm, you should merge the new file

(/opt/wlm/newconfig/etc/rc.config.d/wlm) with your /etc/rc.config.d/wlm

file

Performance

Performance is improved when WLM is used properly, but can degrade when WLM is not

configured appropriately.
