Hi,
today marks a first:
Both controllers of one of our aruba mobility controller clusters crashed. Or at least i think they crashed, as i do not know what actually happened. I'm certain they rebooted though, causing a temporary outage at one of our locations.
The controllers came back on their own after about 15 minutes.
Both are 7210 Controllers, running 8.12.0.2, upgraded from 8.11.2.2 just a week ago.
They are fully clustered, but due to an unrelated VLAN messup currently only a L3 cluster.
Both controllers went offline in the span of 5 minutes.
One controller does have a crash.tar, but that has only information about two older crashes three years ago. The other controller does not have a crash.tar at all.
A "show crashinfo" shows "datapath" as process name, on both controllers. The timestamp correlates to our outage, and to where syslog messages stopped.
I checked the syslog messages, but nothing catches my eye that points to a reason for the reboot.
How would i proceed in finding the underlying issue?
