Troubleshooting


Problem

/etc/resolv.conf file gets replaced at every boot due to RHEL Network Manager.

Resolving The Problem

1.Can you change the network manager to not do that or to disable it? 

Yes

2. Is network manager requires for PowerVC to work?

No

3. Is it going to effect PowerVC?

No

 To make sure that Network Manager will no longer modify your DNS configuration, you could simply stop using it and revert to the original networking manager.  To make changes to the active, running system, only effective from now until next reboot:

 

systemctl stop NetworkManager

systemctl start network

To make the changes permanent, effective at the next reboot and all future reboots, issue the following commands: 

systemctl disable NetworkManager

systemctl enable network
