What version is it? As far as I know from version above 6.0, you have to install the CUCM software in a virtual machine(for educational purposes). The software MUST be installed in a MCS server for production purposes.
Thanks a lot for respond carlitos. I use version 8.0 and i've installed the software in MCS server for production purposes. Yesterday, i've reinstalled back my server using installation cd given by Cisco. After one night and today i've found the error "EXT3-fs error (device sda6) in start_transaction: Journal has aborted" occurred again.
It is because of the hardware corrupted or any other reason? Because it just happen at 'device sda6' only.
