Network Errors During Installation
During the installation process, the installation program verifies that the server can successfully connect to the network by using the network configuration that you enter. If it cannot connect, a message displays, and you get prompted to select one of the following options:
-
—RETRY - The installation program tries to validate networking again. If validation fails again, the error dialog box displays again.
-
—REVIEW (Check Install) - This option allows you to review and modify the networking configuration. When detected, the installation program returns to the network configuration windows.
-
Networking gets validated after you complete each networking window, so the message might display multiple times.
-
—HALT - The installation halts. You should use the Recovery CD to recover the logs to access the diagnostic information. For more details, see Obtain and Run Recovery Software on the CUCM VM.
Note
We no longer support the collection of logs by dumping them to serial port due to CentOS limitations.
-
—IGNORE - The installation continues. The networking error gets logged. Sometimes, the installation program validates networking multiple times, so this error dialog box might display multiple times. If you choose to ignore network errors, the installation may fail.
Steps to Recover Logs using Recovery CD
You should use the Recovery CD to recover the logs to access the diagnostic information. Follow the steps mentioned:
-

Once the recovery CD menu comes up, press Alt + F2 to get to the command prompt.
