Environment

Novell ZENworks Configuration Management 11.2.2 Imaging
Novell ZENworks Configuration Management 11.2.3 Imaging

Situation

When attempting to image a device using multicast, the device PXE boots loading the imaging environment and then errors out with "Could not get local MAC address".

ifconfig shows the NIC as being named em1 or pxpx instead of eth0 as expected.

hwinfo shows the NIC as being there but the Device File or name is not eth0 as expected.

Examples from hwinfo output:

Resolution

This is fixed in version 11.2.4 - see KB 7012027 "ZENworks Configuration Management 11.2.4 - update information and list of fixes" which can be found at https://support.microfocus.com/kb/doc.php?id=7012027

Cause

In Linux kernel updates to the imaging environment, NICs can be named differently than eth0.
