Re-edit the /etc/dhcpd.conf File Any Time cluster

This task applies only to systems using a Myricom interconnect or QsNet^II interconnect with DHCP.

Any time the cluster_config utility and discover commands are rerun, the contents of the /etc/dhcpd.conf file are overwritten. If your system is using a Myricom or QsNet^II interconnect, you customized this file to configure the interconnect switch line monitoring cards, and therefore, your customizations are lost.

“Save the Contents of the /etc/dhcpd.conf File” in this document instructed you to save a backup copy of the /etc/dhcpd.conf file, so you should have a backup copy available.

Follow this procedure to restore the contents of the file:

Use the text editor of you choice to open the /etc/dhcpd.conf file.
Use the text editor of your choice to open the /etc/dhcpd.conf.ORIG file.

Merge the customizations you made to the backup copy of the file when you configured the switch monitoring line cards into the /etc/dhcpd.conf file.




	Important: Do not replace the newly-created `/etc/dhcpd.conf` file with the entire contents of the `.ORIG` backup copy because the new version of the `/etc/dhcpd.conf` file may contain new or additional information that is not present in the backup copy.

Save your changes to the /etc/dhcpd.conf file.
Restart the dhcpd service:
# service dhcpd restart

Re-edit the /etc/dhcpd.conf File Any Time cluster_config or discover is Rerun
