So I used the Web UI to upgrade the management server. During the upgrade process I created a snapshot image (as mentioned in the upgrade process window).
According to the Web UI, the upgrade was successful.
So after the management server was upgraded, I upgraded it to R71.20.
After the upgrade process I couldn't event log into the Web UI.
When going through the fwm.elg it mentioned that fwm process didn't start.
I will explain the details about this specific issue in another post. In this post I will emphasize on how to revert back the snapshot image created in the R70.30 environment, in R71 environment.
So when I tried to revert the created snapshot image (pre_upgrade_snapshot.tgz) it failed. I tried numerous times but the result was the same. This is due to the fact that the snapshot image and the current running version have dissimilar major releases (R70 and R71).
"revert"ing does not support between two major releases.
This true if you try do it on the boot-up process, with snapshot image management.
So in this kind of a situation the easiest way to revert back to the earlier snapshot is as follows.
- Uninstall all the new packages related to R71
- issue "rpm -qa | grep R71"
- this will give you all the rpms installed for R71
- using "rpm -e" uninstall all the related packages for R71 - The use the "revert" command and select the previous snapshot image
