I tested the updated anaconda.pm and it resolves the "bootnic" issue - thank you yangsong.
Unfortunately, I find myself in the same situation as before, namely the postbootscripts do not run after a reboot. The issue here is that during Anaconda run, it creates ifcfg-eth1 through ifcfg-eth4. The boot options specified on kcmdline (IP address, DNS, netmask) get baked into ifcfg-eth1. However, when the node reboots, the devices are enumerated starting with zero, ifcfg-eth0 through ifcfg-eth3. The result of this is that "eth1" doesn't start because there is no physical connection. The correct interface should be eth0. This could be a problem with Anaconda. So I have to run a custom bootscript in either case: 1) I fix “ifcfg-bootnic” and change the DEVICE line; or 2) I fix “ifcfg-eth1” and change the DEVICE line. I’m not sure why this is such a pain, other than the insistence on “old” interface names. I will look into living with the new “better” names. For reference, this is xCAT Version 2.12.2 (git commit e4a7359d31008d81c4c57e0857d5f09009a3269c, built Thu Aug 18 06:43:29 EDT 2016) site.managedaddressmode=static noderes.installnic=mac noderes.primarynic=mac in the osimage definition: addkcmdline=net.ifnames=0,biosdevname=0 Using "mac" seemed like the clean way to handle interface names in RHEL6. I tired setting the installnic to eth0 and it didn’t work. It looks like Anaconda really wants to start enumerating the interfaces with 1. FYI, I experimented with setting “ifname=eth0:<mac>” and it did not work. That explains why “bootnic” logic was added at some point. If we add ifname=eth0:<mac> to the kcmdline, Anaconda will complain: “Warning: ifname=eth0 uses the kernal namespace for interfaces. This can fail for multiple network interfaces and is discouraged! Please use a custom name like "netboot" or "bluesocket" or use biosdevname and no ifname= at all.” From: Song BJ Yang [mailto:yang...@cn.ibm.com] Sent: Wednesday, September 14, 2016 10:30 AM To: Xiao Peng Wang <w...@cn.ibm.com>; russa...@comcast.net; hille...@rhrk.uni-kl.de Cc: xcat-user@lists.sourceforge.net Subject: Re: Fw: Re: [xcat-user] SL7.2 and ifcfg-bootnic hi, This seems to be a bug, I will fix it soon.

I encountered the same problem using RHEL7.2 and I also have "managedaddressmode" set to static. Recapping, after installation, there exists an "ifcfg-bootnic" file with the IP address, DNS settings, netmask, etc configured inside of it. The problem is that the device specification in the file is also specified as "bootnic". Of course, there is no such device on the system, which means that after the first reboot, there is no network connection and the postbootscripts do not run. -----Original Message----- From: Russell Auld [mailto:russa...@comcast.net] Sent: Friday, May 20, 2016 9:04 AM To: 'xCAT Users Mailing list' <xcat-user@lists.sourceforge.net <mailto:xcat-user@lists.sourceforge.net> > Subject: Re: [xcat-user] SL7.2 and ifcfg-bootnic You could remove/unset "managedaddressmode" and use a postscript to change the nic config from dhcp to static. We used to use a combination of "confignics" and "hardeths". You would need to be running dhcpd on the master node for that to work. -----Original Message----- From: Dr. Markus Hillenbrand [mailto:hille...@rhrk.uni-kl.de] Sent: Friday, May 20, 2016 1:32 AM To: xCAT Users Mailing list <xcat-user@lists.sourceforge.net <mailto:xcat-user@lists.sourceforge.net> > Subject: Re: [xcat-user] SL7.2 and ifcfg-bootnic Hi, managedaddressmode is set to static because the default value is dhcp which we do not want to use.
