I try upgrade ACS 184.108.40.206 to new version 220.127.116.11. Everything looks ok:
ACS-machine/acsadmin# application upgrade ACS_18.104.22.168.tar.gz rep01
Do you want to save the current configuration ? (yes/no) [yes] ?
Saved the running configuration to startup successfully
% CARS Install application required post install reboot...
Broadcast message from root (pts/0) (Thu Dec 6 23:36:41 2012):
The system is going down for reboot NOW!
Application upgrade successful
But ACS machine (vmware instance) can't boot with this result: Volume group "smosvg" not found. (for details see attachment)
