How to install RHEL 6.10 currently asking for second disc

Good afternoon everyone. I am a LINUX newbie. Currently I am trying to install the RHEL 6.10 version on our virtual machine. For background we are running Vsphere 7.0 as the environment. The install was running I chose "DESKTOP" as the instance the system then ejected the DVD and asked for DISK 2 to complete the install. Our configuration manager had stated that he downloaded the "binary" version of the ISO to DVD (not sure what that means). Is this a issue of formatting prior to downloading and burning to the DVD or is this something that needs to be fixed and pointed to within the DVD prior to attempting the install not sure where the issue lies to complete the install. Also can someone explain what/how to properly split the install into 2 parts if that is the fix- Thanks in advance
