Changing the System Name of a BRMS System

Learn how to change a BRMS system's name

Inherent in a system name change is a change in the default local location name, and hence, a change for BRMS. When this happens, BRMS does the following:

Updates the network to remove the old system name and add the new system name.
Transfers all of the media previously owned by the old system name to the new system name.

If system is not in a BRMS network

To change your system name, take the following steps:

Change the system name , Default local location name and IPL.
Ensure no BRMS activity occurs on the system between the IPL and adding your system name to the BRMS network. Also ensure that you have a copy of the latest save of the BRMS QUSRBRM library.
Enter GO BRMSYSPCY on the system for which you have just changed the name.
Select option 4 (Change network group) from the System Policy menu. On the top right corner of the display, you can see your new system name.
Select option 4 (Remove) to remove the old name. Press Enter to confirm the name you want to remove.
On the Confirm Remove of Network Systems display, specify *RENAME on the Remove media field so that BRMS can transfer ownership of the media inventory from the old system to the new one.

NOTE: If you did not specify *RENAME on step 6 and left the default *NO, you can use INZBRM OPTION(*CHGSYSNAM) to change the ownership of the media.

NOTE: After you change the system name and perform the IPL, you must change the BRMS network immediately. BRMS did not yet update the media inventory to reflect the name change. This means that the old system name still owns the media volumes. Additionally, the other systems in the network will continue to attempt to contact the old system name because they are not aware of the name change. To avoid missing any information in the shared media inventory data, you must change the BRMS network immediately after the IPL.
