Bootvar and boot command

 

Hi all,

 

 I have recently upgrade our Failover Active/Standby ASA software. Everything works flawlessly. Except I have the following question regarding the boot and bootvar command.

 After the upgrade, both devices come with the new IOS image. However, when I issue show bootvar command, it displays the old image. I also in the running config, the command boot system dish0/.... still points to the old image. Yet show run config, and show ver  display the new image.

 

Now, concerns... If the ASA  reboots, would it come back with the new image, even though the boot system in the running config is pointed to the old config?

 

2. IS it better not taking the risk, and just update the running config with the new image?

 

Thanks,

1) If you reboot it as it is

1) If you reboot it as it is then the firewall will used the image set in the boot'system/bootvar variable.

 

Make sure you fix this before rebooting.

 

How to:

configure terminal

clear configure boot

boot system flash://new-image.bin

wr

Then 

sh run boot 

 

If it's showing the new image you are good to go.
