Today we upgraded a XG450 HA Cluster from 18.0.3 to 18.5.1
Everything seemed to work fined, both appliances showed 18.5.1 on the display.
after we reloaded the cluster, both appliances reverted back to 18.0.3.
from the GUI i could see that 18.5.1 was installed in the 2nd partition but was not booted.
then I tried to boot it manually, by hitting the boot firmware button, which caused the cluster to relead with 18.5.1 but after a few minutes reload again with 18.0.3
same result when hitting the "download&install" button.
which logs to check?
