CUCM upgrade from 11.5 SU3a to 11.5 SU11 Failed

[Ivandy Muchlis]

Currently we have issued when upgrade CUCM to 11.5 SU11. Sometimes the GUI process Install freezes, we try to refresh and the process is running again, but when the install process running for 3 hours and freezes again, suddenly when we refresh the install process cancels itself. The ISO unmounted from CD and we check CPU from RTMT is 99%. But the latest version has appeared in inactive version. I attached log install 

Please Advice for me

Have you tried to run the upgrade from CLI?

[Ivandy Muchlis]

I tried to upgrade again but there was a different error I attached the log and display error 

Error encountered: An unknown error occurred while accessing the upgrade file. Warning: A system reboot is required when the upgrade process completes or is canceled. This will ensure services affected by the upgrade process are functioning properly.

can anyone explain? Please Advice for me

What is the SFTP/FTP software that you use to provide the file to your CM for the upgrade process? There has been many previous posts in the community about issues during upgrades and for the most it drills down to issues with the software used to provide the files.

We have since long selected to go for the option to use FTP as the protocol and have a FileZilla server to provide the file to the upgrade process in CM. This has worked well for us.

I believe you need this cop applied before Upgrade to SU8

https://www.cisco.com/web/software/282204704/18582/ciscocm.CSCvv21530-upgrade-fix_C0074-v1.cop-Readme.pdf

This COP file provides a fix to address the following issue:
CSCvv21530: Onmode Utility gets stucked due to stale references present for .infos shared memory file in
/partB
The 11.5.1SU8 release of the above Cisco products has a new version of Informix. An intermittent issue has
been discovered where the upgrade may get stuck due to a configuration file that already exists on the inactive
partition when the upgrade is attempted. When this issue is hit, the following will be seen in file view install
cancel.log:
07/22/2020 13:37:01 sd_cancelInstall.sh|This is not a COP, so will do IDS shared memory clean up if needed
on inactive partition
07/22/2020 13:37:01 sd_cancelInstall.sh|Stopping Partition B IDS
Installing the above COP file will allow the next upgrade attempt to succeed without issue

I don't think there are readiness COP files available for 11.5, but have you checked that the servers have enough available space? There are COP files to free up space from the common partition if you are low there.

Hi, 

Are you using local ELM server on CUCM or another instance?

Try to stop these services and install again 

Cisco ELM Admin
Cisco ELM DB
Cisco ELM Server
