ISE Patching

[erajca]

Experts,

We have a scenario where we have installed patch 3 on an ISE 2.0 distributed deployment where most nodes were successful however 2 PSNs were not online during the patch install.

Now that the 2 PSNs are back online, can we still invoke patch 3 install for the remaining 2 PSNs through the GUI without affecting the already installed nodes or do we need to perform this install through CLI for these 2 remaining nodes ?

Thanks,

Ed

It seems the two nodes were offline for some significant amount of time. I would suggest to install the patch from ISE admin CLI and perform manual sync-up.
