The System status field on the Change Network Group display should provide you with an easy means of determining whether the current system is communicating with the other networked systems. A status of Online indicates that synchronization is running between the two systems. A status of Offline may be an indication of a problem.
You can take the following steps to run a daily check of media synchronization:
RMVMEDBRM VOL(SYSxx) MEDCLS(NETCHK)
Delay Job (DLYJOB) DLY(300)
ADDMEDBRM VOL(SYSxx) MEDCLS(NETCHK).
Assuming that the current date is July 6, 2005, the WRKMEDBRM command for each system should display the following information:
Work with Media SYSTEM01 Position to . . . . . . Starting characters Type options, press Enter. 1=Add 2=Change 4=Remove 5=Display 6=Work with media set 7=Expire 8=Move 10=Reinitialize ...

Parameters or command: ===> _________________________________________________________________________ F3=Exit F4=Prompt F5=Refresh F11=Volume system F12=Cancel F17=Top F18=Bottom F23=More options
Press F11 to view the owning system. Reviewing the following display, you might conclude that SYSTEM01 did not receive the SYSTEM04 media update.
Work with Media SYSTEM01 Position to . . . . . . ______ Starting characters Type options, press Enter. 1=Add 2=Change 4=Remove 5=Display 6=Work with media set 7=Expire 8=Move 10=Reinitialize ...

Parameters or command: ===> __________________________________________________________________________ F3=Exit F4=Prompt F5=Refresh F11=Volume system F12=Cancel F17=Top F18=Bottom F23=More options
In this case, it could be that a communications problem occurred subsequent to July 4th.
