Express5800/ftServer: System Administrator’s Guide for the Linux Operating System
If the operating system reinstallation failed or you want to return the system to the
previous operating system version, see ‘‘
Recovering from a Failed Software Upgrade’’
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 4-6
.
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.
