Christian, The ifcfg-eth0 already had BOOTPROTO=static, and NetworkManager is not installed.

We use xCAT and the associated DHCP functionality for system provisioning and upgrades, but all of our nodes normally have static IP addresses.

At the same time, for example, ifcfg-eth*.xcat files are created. I suspect that dhcp is doing this, but would like to confirm before I try to remediate.

You should be using the current 2.8 release - 2.8.3. Even using 2.7 you should be at 2.7.8 by now. Lissa K.

To: "xCAT Users Mailing list" <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Rod, You need to make sure your ifcfg-eth* files have BOOTPROTO=static before you restart the interface. Also make sure you have the NetworkManager package uninstalled and/or NM_CONTROLLED=no in the ifcfg-eth files.
