The operator entered a SET command with a GRSRNL keyword, but system sysname is already performing a SET GRSRNL command.
The system ignores the GRSRNL keyword of the SET command on this system.
System sysname is already performing an RNL change. If a second RNL change is desired, enter the SET GRSRNL command after system sysname completes or cancels its SET GRSRNL command.
Determine the status of that RNL change on system sysname by looking at the messages issued on that system. Enter the DISPLAY R,L,CN=(ALL) command to find outstanding prompts for the RNL change.
