Upgrading or Restoring the Linux Operating SystemUpdating the Operating System and Express5800/ftServer System Software 4-3• To preserve your changes, incorporate the updates into the files you have modified.Compare files in the /etc/OPT/ft/network-scripts/ARCHIVE directory thathave a .rpmnew extension to your modified files, and copy the updates from the.rpmnew file to your modified file.For example, if you added a port to the bond defined in the/etc/sysconfig/network-scripts/ifcfg-bond0 file and if the RPM file for theupgrade contains an update to the ifcfg-bond0 file from the earlier RPM file, theupgrade process copies the updated ifcfg-bond0 file from the new RPM as/etc/OPT/ft/network-scripts/ARCHIVE/ifcfg-bond0.rpmnew. After theupgrade, modify your /etc/sysconfig/network-scripts/ifcfg-bond0 filewith any differences you note in the/etc/OPT/ft/network-scripts/ARCHIVE/ifcfg-bond0.rpmnew file.N O T E S1. Resolve the differences in these files immediately, orback up the rpmsave or .rpmnew files to anotherlocation. If the same .rpmsave or .rpmnew files aregenerated by uninstalling Express Builder, or by anupgrade or reinstallation, the previous archived versionscould be overwritten.2. If you uninstall Express5800/ftServer system software,any of these network files that you modified are savedto the/etc/OPT/ft/network-scripts/ARCHIVEdirectory and given a .rpmsave extension.Upgrading or Restoring the Linux Operating SystemUse this checklist to prepare for the Linux operating system upgrade or reinstallation:❏ Before performing an upgrade to a system in use, perform a complete file systembackup.❏ Carefully read the current Release Notes: Express5800/ftServer for the LinuxOperating System document at http://support.necam.com for this release.Distribution Release Notes may have been updated with information aboutrestrictions or problems and workarounds, software updates, and documentcorrections not found in the Release Notes from earlier distribution CDs. Verifythat the new Linux operating system version you are about to install isintended for installation on your ftServer system.❏ The system that you wish to upgrade must be configured to load from a bootablesystem disk that is in the ftServer system’s boot path.
