WARNING: Ungraceful shutdown detected >>CUCM v12.5 SU4

I have a CUCM cluster with IMP and CUC, the site had a power outage.

 

and then all server nodes have shown these alerts

"

 

 

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.

 Do I need to rebuild all nodes again, or is there a workaround to eliminate these alerts?

Thanks all of you for your answers,

 

I have opened a case with Cisco TAC and I will share his answers with you:

 

 

Q:But if the servers were working fine, could I continue with same installation without doing the process of rebuilding new servers?

A: No, you can not continue, by TAC it will be considered as unsupported.

 

 

Q:Also, can I clear these alerts that comes to GUI ?

A:no, not possible

 

Q:Last question, can I take a copy for the VMs and used them to be restored if the servers hit the ungraceful shutdown again ?

A: It is possible to take cold snapshot via vmware (after shutting down the system).

We used to have Ungraceful shutdown  in our data centers, But never seen such a warning on our CUCM  12.5 SU1.

 

I Would recommend to contact TAC to verify your system and confirm everything is good.

This is something new which is added in new versions. Recently I had unity connection publisher go down unexpectedly. After I powered it on, GUI didn't show this warning message but CLI did. I performed system verification and tests to make sure all the features that are configured working or not. All the database replication, diagnose test, cluster status etc. looked good and so far I did not hear any issues from users. In your case, make sure all the features and functionalities are working or not. And as @Nithin Eluvathingal mentioned, open Cisco TAC case if you want more clarification or recommendation from TAC Team.

I have been noticing this with 3 of my customers now that have had un graceful shutdowns and I have to rebuild everything.  Pushed them into finally replacing their UPS systems we have been recommending...

I wish this wasn't added, as I agree, everything is working as normal, but that message will never go away and then TAC won't support.

 

Good to read in other comments that this was new with the latest updates.

We have the same issue but TAC did NOT say it would not support us if we didn't rebuild the servers.  We were told it is a message that was newly introduced in 12.5.1 SU4. Since rebuilding a system after a power outage has never been indicated previously and is a significant action to take when no problems appear to be present, we are not rebuilding our servers.  We have an open enhancement request with Cisco TAC to provide a way to clear this alert and are living with the notice in the meantime.

There is a bug for a tool which would check the system and might provide the ability to remove the message

Checked that link and it says a Tool is needed.  The link above goes to a request to create a tool and says that currently there is no work around.

FYI: I got the same error on our lab server running 14.0.1.10000-20. I just upgraded it to the latest beta, 14.0.1.11900-57 and the error message went a way.

@jeremy.worden  are we entitled to share such information on a public forum ? Hope you signed  NDA when you applied for beta program.
