NimbostratusCreating an iRule Data Group via bigpipe?
Is there a way to create a Data Group for an iRule via a bigpipe command like I can for pools?
Maybe something like: bigpipe datagroup Name {members 1.2.3.4 2.3.4.5 3.4.5.6}
I need to update an existing one to replace the current IP list with a new list. I don't know if I can delete the group first if it's accessed in a working iRule or not as well.
Thanks.

A while ago I was struggeling with creating a new datagroup via bigpipe.
There is a man page about it. But didnt work for me.
I would recommend to get an excerpt of your current datagroup stored in /config/bigip.conf and to create an adjusted version with a new name in a file to be stored in /var/tmp/my_new_data_group.
You can merge it into your running configuration with:
bigpipe merge /var/tmp/my_new_data_groupSave the configuration:
bigpipe saveNow you can replace the referenced data group in your iRule. New connections should be handled by the iRule according to the updated datagroup.

Here are a couple of articles from Jason Rahm on data group formatting for v10 and v11:

The bigpipe guide should have more info as well.

kelemvor_50002So I got it to work on one of our F5s since it's older and supports Bigpipe. However our newer one doesn't support bigpipe any more. :(
I guess I have to go read up on tmsh...
