HotFix implementation issues. F5 fails to load config after activating patched volume.

Did you check the license date and service check date. Did you reactivated license prior upgrade.

what is the output for
tmsh load sys config 

Any errors in /var/log/ltm would be helpful

Yeah you know we did this last year and I remember on some of the devices we refreshed the license. I did not attempt this on our pre-production device and it wasn't required on our two test appliances. I did have that thought though. I will check the information you requested. Thanks!

Well nothing much error wise in the ltm file and forgive me but....I'm only familiar with using the GUI and not the command line. I guess I'll try reactivating the license before upgrading...I thought this was more geared towards an actual version upgrade and not hotfix. One would think it would say something like "License Expired....LOLOLOL" something like that when booting, but its worth a try! :)

Update on this. I tried the license reactivation before hotfix deployment and I received the same error "The configuration has not yet loaded. If this message persists, it may indicate a configuration problem. I tried rolling back to UCS archive and still received the same errorm and was unable to activate other volumes any attempt displayed the error. I tried loading the UCS through console and this revealed the underlying error which was a parser error, and the load aborted. We contacted F5 support and Tom worked his magic pinpointing the error through some F5 wizardy. The config was failing due to an iRule in the config...the iRule syntax was correct he re-arranged some things and cleaned it up a bit, and we were able to load the config. Thus saving my job. He didn't mention the exact issue just that he re-arranged it other than the entire iRule being on ONE line. Anywho......17 hours spent but in the end the appliance is breathing again.

Cheers
