This is my favorite new Cisco "feature". All the 14.x platforms have this. I
think they implemented in 12.5(su4 or 5), but if the system goes down dirty,
the official Cisco policy is to do a restore from backup. So far, I haven't
had any actual issues after this happens, but if your system is in this state,
TAC won't help you until you've rebuilt. There are a few options for graceful
shutdown in VMWare, but your server needs to be on a UPS for them to work.

I need to find it, but of course can’t right now, but I swear this is in the ER

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.
https://www.cisco.com/web/software/286319173/139477/ciscocm.add_utils_ungraceful_warn_disable_v1.0.cop-README.pdf
>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.

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.
