2)Create the remote controller manually .

Method 1

Ensure sysval Qautormt =1 on wrksysval Qautormt ,change the system value
The AS/400 will autoconfig and restore the entire configuration.

Method 2

* If the attached devices (work stations) were auto-configured and renamed ,and you do not want the AS/400 to auto-configure.
Before deleting any descriptions check system value (Qautormt) 0= disables auto configuration
