F5 Load balancer not working, but all the configurations are successful

Hi,

I checked bigip_error_maps.dat (in /var/run/ folder) looking for both 01200004 code as well as "rejected" word and nothing was returned matching posted entry, I was pretty sure that everything that is placed in ltm log should have entry in this file - am I wrong?

Considering problems with this VS - what version of LTM are you running? Can you ping selfIP of this LTM on the VLAN you have your VS defined? Actually Virtual IP used by VS should reply to ping even if VS is disabled or pool is down. This can be turned of in "Local Traffic ›› Virtual Servers : Virtual Address List ›› your VIP name" by setting ICMP Echo to disabled (this option is available with new versions, I thing 11.5+). You can as well disable icmp using Packet Filter. Still both those options are not creating any entries similar to posted in my ltm log.
