Add/Remove/Rename servers

• Add new server
  Suppose you connect a new server to the HMC which is already under LPAR2RRD
  Only the thing you need to do is allow utilization data collection for that server
  Log on to the HMC and set sample rate to 60secs globally, then check whether it is ok

  hscroot@hmc1:~> chlparutil -r config -s 60  
  hscroot@hmc1:~> lslparutil -r config  -F name,sample_rate  
  PWR6A-9117-MMA-SN103A4B0,60 
  

• Remove old server
  • There is a functionality which should stop the server appearing in the WEB when it has not been updated for more than 10 days.
    It only stops the server from appearing on the web page, the data still persists there.
  • You might only exclude the server from procesing & displaing via directive MANAGED_SYSTEMS_EXCLUDE in etc/lpar2rrd.cfg.
  • complete removing jnclude data:
    (there is one dir and one sym link to that, delete both)

    $ rm -rf  /home/lpa2rrd/lpar2rrd/data/__managed_system__
    

    then remove server web data:

    $ rm -rf /home/lpar2rrd/lpar2rrd/www/__HMC__/__server__ 
    

• Rename the server
  You can rename the server whenever, LPAR2RRD recognizes the change automatically and updates the web page during next run. Nothing will be lost.
