Normally with just disk 2 it will work. (You must be sure that all objects of desired Licensed Program are in disk 2!)
As for “verify”, I wouldn’t expect it to be able to verify. You’re not running an upgrade nor PTF package. You’re simply “loading” a CD/DVD and installing from it. The RSTLICPGM command will find the product or it won’t. It will tell you if it succeeded.
IIRC, if it prompts for the ‘next’ CD, enter the reply that indicates there are no more. (That might be an ‘X’ — it’s not something I do often for single products.)
The worst that will likely happen is a message saying the product wasn’t found. Be aware that you should probably apply your last cume PTF package again after a new product is installed.
