Upgrading or Restoring the Linux Operating System
Updating the Operating System and Express5800/
ftServer
System Software

•
To preserve your changes, incorporate the updates into the files you have modified.
Compare files in the
/etc/OPT/ft/network-scripts/ARCHIVE
directory that
have 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 the
upgrade contains an update to the
ifcfg-bond0
file from the earlier RPM file, the
upgrade process copies the updated
ifcfg-bond0
file from the new RPM as
/etc/OPT/ft/network-scripts/ARCHIVE/ifcfg-bond0.rpmnew
. After the
upgrade, modify your
/etc/sysconfig/network-scripts/ifcfg-bond0
file
with any differences you note in the
/etc/OPT/ft/network-scripts/ARCHIVE/ifcfg-bond0.rpmnew
file.
N O T E S
1. Resolve the differences in these files immediately, or
back up the
rpmsave
or
.rpmnew
files to another
location. If the same
.rpmsave
or
.rpmnew
files are
generated by uninstalling
Express Builder
, or by an
upgrade or
reinstallation, the previous archived versions
could be
overwritten.
2. If you uninstall Express5800/
ftServer
system software,
any of these network files that
you
modified are saved
to the
/etc/OPT/ft/network-scripts/ARCHIVE
directory and given a
.rpmsave
extension.
Upgrading or Restoring the Linux Operating System
Use 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 system
backup.
❏
Carefully read the current
Release Notes: Express5800/
ftServer
for the Linux
Operating System
document at http://support.necam.com for this
release.
Distribution Release Notes may have been updated with information about
restrictions or problems and workarounds, software updates, and document
corrections not found in the Release Notes from earlier distribution CDs.
Verify
that the new Linux operating system version you are about to install is
intended for installation on
your
ftServer system
.
❏
The system that you wish to upgrade
must
be configured to load from a bootable
system disk that is in the ftServer system’s boot path.
