Use this procedure to install Linux for software-only installations.
Important:
Avaya recommends installing only required RPMs to the system for security and stability. Do not install the complete Red Hat system.
Important:
Changes to the default kernel boot time parameters can result in an unstable or inoperable behavior of Avaya Aura® application. You must take care when altering the RHEL Kernel boot options. If issues arise with Avaya Aura® application where kernel boot options have been customized, Avaya recommends to restore the kernel options to the defaults to determine if the customization of kernel boot options are the cause of any undesired behavior.
Important:
Session Manager supports running with SELinux set to enforcing. SELinux can be enabled prior to installing Session Manager or after installation.
Warning:
Additional SELinux rules, besides the default one included by Red Hat, may cause Session Manager not to work properly. Avaya should be consulted prior to adding any additional SELinux rules.
