I have two asa5520s and they are configured as active/active failover and multi-contents.
Now, I need upgrade their images. But, I find:
1. On the asa5520 which content admin is active, I can go to system by (changeto system) and I can upgrade the asa image and adsm image.
2. On the asa5520 which content admin is standby, I can not go to the system side,
Command not valid in current execution space.
Could anyone advice me:
how can I upgrade the image for second box?
is my configuration of failover/multi-contents wrong? If so, how to configure the failover/multicontents to allow me able to go to system space on second box?
Any comments will be appreciated
Thanks in advance
There is no shutdown command available on ASA. We would need to walkup to the device and manually power it off.
On step7, "can I first power on ASA1 and after ASA1 take control, than shutdown ASA2?"
This will not work, because when ASA1 comes up, there would be a conflict as both are running on different version. It may cause other issues in the network thus I would not recommend doing so.
Hope that helps.
