Policies

If a cluster node is running antivirus software and behaving in an unexpected manner, Red Hat may require that you reproduce the issue with the antivirus software disabled. If disabling the antivirus software causes the issue to disappear, then you will need to do one of the following:

• Temporarily and for the purposes of troubleshooting, disable the antivirus software in current runtime and persistently ( so it does not start automatically on reboots ).
  • The intent will be to be re-enable the service upon disqualifying antivirus software as a factor in the issue ( issue re-occurs even with software not running ), or upon correcting any issues on antivirus side which may trigger the issue ( if issue does not re-occur while disabled ).
• Work with the antivirus software vendor to troubleshoot and remediate the issue within the antivirus configuration, so that it doesn't disrupt the Red Hat High Availability software.
