Remote Console was set up and now messages from other LPARS are not displayed properly.
In the RCS.CMDLIB you should enter the following statement:
K S,DEL=RD,SEG=16,RNUM=16,RTME=1/4,QTME=999,MFORM=(J,T,S,M)
This is documented in the Remote Console Reference Guide pages 2-59
Each Remote Console will either share the same RCS.CMDLIB or have their own. This command says to acquire all messages; MFORM=(J,T,S,M) is the important statement.
