f5 enterprise manager fails to connect to LTMS

Hello,

I have a handful of ltms that cant communicate with EM. There is about half that can talk to the the EM and half that cant. The LTMS are 11.4.1 and EM is 3.1.0. The EM talks to the LTMs fine with iquery communication in the dump logs being ok.

On of one of the LTMs in question it was discovered by an engineer who is still working on the case that I have already open, he found these errors on one of the LTM's a couple of days ago:

67  May 21 14:44:18 aprcorpextltm1 err eventd[8174]: 012d0012:3: Notification attempt to consumer id D6E738E8-   1974-626A-2E52-EF1569494AD FAILED with error Failed to connect to host 10.58.1.124, port 443: Operation already in    progress.

Anyone run into this before ?

Thanks

    I am actually dealing with the same thing right now. The problem is probably a firewall blocking the communication that the LTM initiates with the EM. The real question is though, is it initiating the connection through the management interface or one of the traffic interfaces/IP's? Then if you have a self IP configured on the EM as well, which IP on the EM is the LTM trying to communicate with? Once you figure that out, you should be able to open up your firewalls appropriately.

    Come to find out (as it was my suspicion before) is that there was missing a management route on the ltms in question. I tried iptables but wouldn't work properly to add it. Had to add the routes in tmos.

     

    few things to verify/check:

     

    -issue ip route view output on the ltm shell cmd -netstat -nr - view routing tables -issue tmsh cmds tmsh list /sys management-route, and tmsh show /net route view output

     

    This solution article guided me that helped resolved my issue.
