Is there a failsafe way of installing 24.11 remotely (on 2100)?
-
I fundamentally know the answer is "NO" to the question, but....
As I understand it 24.11 will just clone the existing boot environment and upgrade the new clone while the firewall is still running from the original boot environment.
So doing the upgrade itself should never cause disconnection or the dreaded reboot while upgrading right?Is there a way to setup a One time reboot into the newly upgraded environment, and have it return to the original image at next power off/unplug event - regardless of a successful boot or not on 24.11?
I dread a few possible outcomes of a remote upgrade:
1: in case it does not correctly register it failed to boot the newly upgraded boot environment and keeps trying at every reboot.
2: My special WAN DHCP Client config does not work on 24.11 but It will boot successfully and thus not return to the old environment - but also not come online for remote access/config again.Since I have people onsite @ my remote box, it would allow me to have them remove the power plug - which should make it reboot successfully into the old environment again.

By default it will still reboot into the new BE during the upgrade it just does so after the new BE has been upgraded which means far less downtime.
But there are options. In the Update Settings you can set 'Defer Automatic Reboot' so it will not reboot until you do so manually. You can set one-time reboot in the BE settings.
I could easily imagine getting confused there though! Let me run a test....

Yup that works. So set reboot to defer. Then go to Boot Environments, you will see the temporary BE setup during upgrade. Choose to reboot into that one time.
It will boot to that and remove the temp tags but leave the 'next boot' marker against the old BE so power cycling will restore it.

Excellent little "workaround" :-)
Thanks, I'll give it a spin, but I already upgraded my local 2100, so even though I'll use this trick on the remote box, I don't assume there will be issues upgrading it to 24.11

Yup I wouldn't expect any issues on a 2100. But you can roll back and test it locally.
Of course custom options are always a risk to some degree.
