Upgrading Or Restoring Express Builder - NEC Express5800/ftServer Administrator's Manual

Upgrading or Restoring Express Builder

If the operating system reinstallation failed or you want to return the system to the
previous operating system version, see
on page 4-8.
Your system should now have the same version of operating system software installed
as it had previously. But since it has no Express Builder software, its fault-tolerant
features are not operational, so you must upgrade or restore Express Builder on your
system. See ''Upgrading or Restoring Express Builder'' on page
Upgrading or Restoring Express Builder
Prepare for the Express Builder upgrade using this checklist:
Before performing an upgrade to a system in use, perform a complete file system
backup.
Stop ftlSNMP services before upgrading the Express Builder.
If you upgrade the firmware to support the new Express Builder version, backup the
BIOS and BMC firmware files on your system. If the upgrade fails or if you chose to
return to the previous Express Builder version after the upgrade, you will need these
files to return the firmware to its earlier versions.
If you must restore an installation whose system files are corrupt, this upgrade may
fail. To ensure that Express Builder is performing correctly, you should either perform
a complete Express Builder reinstallation or restore the system from backups.
Carefully read the current Release Notes: Express5800/ftServer for the Linux
Operating System document on http://support.necam.com. Distribution
Release Notes may have been updated with information about restrictions or
problems and workarounds, software updates, and document corrections that
Release Notes from earlier distribution CDs do not have.
