How to restart processes on an Aruba controller

 Tutorial by: Constantin

Here is a list of commands that we will use and what we can look for:

-          “show processes” – if you used linux then you will love the output. Please check the other parameters of the command in order to see the process that uses more CPU or Memory.

• PROCESS STATE CODES
  • R  running or runnable (on run queue)
  • D  incorruptible sleep (usually IO)
  • S  interruptible sleep (waiting for an event to complete)
  • Z  defunct/zombie, terminated but not reaped by its parent
  • T  stopped, either by a job control signal or because it is being traced

-          “show process monitor statistics” – will display a list of current processes running under watchdog.

-          “process restart <process name>” – will restart the process and in order to see if it has re-initialized you would need to use one of the previous commands.

I would recommend to have an Aruba support engineer with you on the phone when doing this on production and only if the engineer requests you to do so.
