We have a problem on upgrading CUCM 6.0.1(b) to 6.1.2.
Since 6.1.2 can be directly upgraded from 6.0, downloaded ISO image and completed the upgrade installation.
After the upgrade when restarting with the newer version the system not booting. Seems the raid configuration got erased? No Hard disk detecting.
Server is IBM, MCS 7825I2-K9-CMA2. Do anyone met with this issue?
