Small APA configuration testing script which will automate checking and verifying your Auto Port aggregation configuration in the HPUX server.

In the past, we have seen the configuration of Auto Port Aggregation in HPUX which explains what is APA and what is the purpose of using APA in your setup. In another post, we learned how to test APA if working perfectly or not. In this post, I will be sharing a script that I coded to automate this APA test.

Do not run this script on running live production. Since testing APA involves disabling of NIC.

Also, make a note that you need to run this script in normal terminal login and not on the server console. Since if the APA test fails you will lose server connectivity on primary NIC IP address. It is recommended to keep a continuous ping session on to IP address (configured on APA) to make sure that you monitor connectivity during the whole APA test. I have also explained the use of this continuous ping in manual APA test post.

Script code :

Execute this script on your own risk!

See below the APA configuration testing script. Save the below code in apa_test.sh file on your server. Execute script with root privileges using sh apa_test.sh or ./apa_test.sh command. Make sure executable permissions are set for the file.

Sample output :

******* APA Configuration Check *******
Caution !! Do not run this script from console

APA group : 900
IP	  : 10.10.5.2
Lan PPA	  : 0

APA group : 900
IP	  : 10.10.5.2

APA is working normally!
