Introduction This document covers the Procedure for Dumping CUCM Fresh Install Logs - Virtualization   Problem Description In order to dump install logs on a virtual UC installation, it is necessary to use a virtual serial port on the virtual machine. By default, a serial port is not present when deploying from the Cisco provided OVA. Thus it will often be the case that the first time you hit an installation problem and need to dump the logs, the serial port will not be available. Use this procedure to add a serial port to the virtual machine and dump the logs.   Procedure Follow this procedure to dump install logs to the serial port on the VM. 1. When the VM is powered off, edit settings and add a serial port to the VM. Note: You cannot add one while the VM is running. 2. You will be required at this time to attach the serial port to a file. Just attach to any temp/junk file, as this file will NOT be used to dump the logs. 3. Power on the VM and start your installation. At boot up, linux will dump some garbage characters (escape sequence characters) into the temp file you attached to the serial port. 4. When you're ready to actually dump the log files, attach a new, empty file to the serial port by editing settings of the VM while the machine is running. You do not have to power down the VM to change the file attached to the serial port. 5. After the file is saved, you can open it using 7-zip ( http://www.7-zip.org/download.html ) 6. After you have a successful install in the VM, power off the VM, edit settings and remove the serial port from the VM. Note Leaving the serial port (or any other unnecessary virtual hardware) can negatively impact performance of the VM. There is no other use of the serial port in a Unified CM VM other than dumping the install logs, so you will not need it again unless you do a fresh install. ... View more

    Introduction This document covers the Procedure for capturing the logs   Problem Description Fresh install failed.  Need to access the install logs in order to debug.   Resolution If the Installation Wizard presents the option to dump diagnostic info, select to do so that the install logs and a variety of other logs will be bundled and written to a USB Key. If the fresh install has failed, try hitting Alt + F2 on the console.  If that gets you to a responding command prompt, you can access the install.log in /tmp/.  You can get back to the installation wizard by hitting Alt + F1. If neither of the above methods works, you can use the appropriate recovery cd as follows: Insert the recovery CD. Reboot the system. Once the recovery CD menu comes up, hit Alt + F2 to get to a command prompt. Then find the largest partition by doing a "df -h"  (It will be something like /mnt/part6) The install log will be located in /mnt/part6/log/install/ directory. You can return to the recovery CD menu by hitting Alt + F1. ... View more
