Hey Mate ,
The info that you provided is not enough to help you OUT . Can you access the F5 Node through CLI ?
or BOTH CLI and GUI page not accessible ? Can you ping the mgmt interface IP ?
Please provide as much detail as you can . Also , i assume you have a proactive TAC open with F5 for support ?
thank you Deepak!
the problem is fixed. But I have one question to you! : is it true that there is known bug on 13.1.x (that F5 is actually working with, now) regarding the muti-partition BigIP (several config file on several local partitions locally) : when you upgrade from a version to another you should not need to export the file as well, although the versions are on different partitions (which I did). But actually you have to select your config as well.
