How to restart processes on an Aruba controller
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.
- “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.
some license issue we got after upgrading 7030 mc,
we restarted stm process.
managed to solve the issue after that.
but one thing: the output of 'show license server-table' seems weird/doesn't tally with our purchased ap+pefng license.
actual license count=62; our total ap=37 with 1 ap down, so total ap active should be 36.
shown there usedLic=76-84, keeps fluctuating.
i dunno where the number counted from.
attached the logs.
btw, why are we not allowed to upload .7z file?
our hpe tac case # : 5339251096 & 5339398690
Thank you for that information.
Under what circumstances would a user want to or need to restart a process?
Please contact TAC and DO NOT restart any processes. We left this post up as an example of how unpredictable restarting processes are and how it should really only be a tool for engineering or TAC.
For example now in my company we use it in order to clear the station table - because the "aaa user delete all" would not do it properly and we get to max out our user license on the controllers.
We are working with Aruba support to get the issue fixed but in order for us not to restart the controller we restart the "auth" process and that clears the station-table.
Some additional thoughts for your document
I definitely concur with the comment "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." as restarting processes randomly is likely to cause some sort of outage.
