Hello friends,
I need some support urgently. I have called F5 and the operator has told me that the engineers are out.
Please, I follow the steps to upgrade a HA pair and I re-activated the lice...
I carefully performed the upgrade again in a Standalone BIGIP 4000s box. I applied your suggestions and everything worked, except that the configuration could not be loaded, so I issued the "tmsh load sys config" command and it displayed one error about some pool which did not find a corrsponding node. I modified the bigip.conf by using the vi tool. Finally the configuration was loaded and the standalone BIGIP had the 11.5.1 version.
Sincerely, I am afraid of getting an issue related to a fail in the loading of the configuration when I upgrade the HA system. I think the configuration loading must be smooth.
Moreover, I realized that the virtual servers are not attached to a link after the upgrade. I must tell that I do not have an active link in such data center. Maybe, do you have any comment about? Please, find below the images related:
