HI, How can I gracefully shut down my servers of a given pool member for maintenance without disrupting current user sessions using the F5 iControl module??...and of course, allowing for enabling and disabling of the server for a pool Has anyone done this before?

The good news is you have other options. The v11 API [1] was extended to support this functionality, but the module was written specifically for v10 [2]. I don''t know the f5-icontrol 10.2 gem compatibility with v11 API, and F5 haven''t released v11.2.1 gem yet [3]. I think setting a poolmember connection limit would simulate the behavior. The other solution is setup monitoring to watch a service availability and drain stop (not the actual service but a service availability indicator). This is actually quite helpful as it gives the server admin the ability to start maintenance, monitor user traffic drain, all without any load balancer changes [4]. If you are on v11 and willing to work with the provider, you can look at updating this section: https://github.com/puppetlabs/puppetlabs-f5/blob/master/lib/puppet/provider/f5_pool/f5_pool.rb#L66-L74 https://github.com/puppetlabs/puppetlabs-f5/blob/master/lib/puppet/provider/f5_pool/f5_pool.rb#L123-L131 Change the WSDL to LocalLB.Pool, add enabled state property, and change to the appropriate get_member_*, set_member_* methods.

Hi Nan, cool, thanks for your reply. We are running both versions of F5, so i think i will give it a try and see if this works.

Another option (I do not know if this would work), would be to "translate" this script: https://devcentral.f5.com/wiki/icontrol.pspoolmembercontrol.ashx to ruby and execute it when deploying a new application.
