[cisco-voip] Fun message on CER after power outage...

[Adam Pawlowski]

I need to find it, but of course can't right now, but I swear this is in the ER documentation somewhere, some version, that the system must be re-installed if it shuts down unexpectedly. Outside of this message.

I got called out on it by TAC, and they have documentation way preceding that message appearing visibly to point out where unexpected shutdowns have occurred.

There was a back and forth in the community on this, with a lot of people more interesting in making the message go away than trying to figure out if the system was okay or rebuild it.
I guess in some places it is normal to operate the infrastructure on car batteries or what have you. I really must be missing something as this feels like the old "put tape over the check engine light" .

Same thing I said there - personally, rebuild the thing when you can on your time table, instead of having it fail later, or during an upgrade.
CER seems to be the easiest thing to re-install - if you have exports you can replace the system functionality rather quickly even when DRF backups are no good.

Yes - those warnings were making their way around another forum. It all has to do with reviewing the log files for a corresponding manual shutdown for any bootup sequences.

There is a fix (?) for the core apps found here. Normally these should work on CER but it's not listed. Not sure why.

>From the readme (above):

The fix is included natively in 12.5.1SU6 (12.5.1.16900-x) and higher and 14SU2 (14.0.1.12900-x) and higher.

Note: I don't think this fixes the issue, just removes the warning. If TAC reviews the logs and finds an ungraceful shutdown, they can start asking you to rebuild.

PS I don't see why a system can't recover without a rebuild either.

Only on the CLI...

WARNING: Ungraceful shutdown detected - A rebuild of this node is highly recommended to ensure no negative impact(such as configuration or file system corruption). For rebuild instructions, see the installation guide.

The bugs suggest it should only be on 12.5 and early... this is on CER 14...

Any recommendations? This seems a bit extreme...

The system appears to be working normally.
