Step 1:
On the system that you are removing from the network, issue the following command:
WRKPCYBRM TYPE(*SYS)
and select option 4 to Change network group.
This will bring up the Change Network Group panel. Select option 4 (Remove) for all network entries at the same time on the Change Network Group panel.
When selecting option 4 (Remove), you are transferred to the Confirm Remove of Network Systems panel. You should select *YES for the Remove media field if you do not want the rest of the systems to have any information about media owned by the system being removed. If you plan on this system being added to a different BRMS network or to be a stand alone system, then use the *YES option. this will remove all media owned by the other systems in the BRMS network.
Step 2:
On one of the systems remaining in the network group, issue the following command:
WRKPCYBRM TYPE(*SYS)
and select option 4 to Change network group.
Select option 4 (Remove) for the system name being removed from the network group on the Change Network Group panel. This removes the system name from all systems remaining in the network group.
When selecting option 4 (Remove), you are transferred to the Confirm Remove of Network Systems panel. You should select *YES for the Remove media field if you do not want the rest of the systems to have any information about media owned by the system being removed. If you want one of the remaining systems to assume ownership of these volumes, you need to run this step on this system and use the *RENAME option.
