System Administrator Guide
See Procedure 8-24 for information about performing an ISSU on an OS 6400, OS 6850E,
or OS 6855. You can perform the following types of software upgrades:
• Image file
• Boot files
• CPLD/FPGA files (OS 6250 and OS 6450, Release 6.6.3-453R01 and later only)
The following conditions must be present before you can perform a device software
upgrade on an OmniSwitch:
• You have a 5620 SAM user account with an administrator or network element
software management scope of command role or a scope of command role with
write access to the mediation package. See chapter 2 for more information
about scope of command roles.
• FTP is configured in the mediation policy for the NE. See the 5620 SAM User
Guide for more information.
The operational restrictions and requirements for software upgrades on OmniSwitches
are:
• Only OS 9700E, OS 9800E, and OS 10K CMM images can be upgraded.
• The following CMM images are ISSU capable:
• For OS 9700E and OS 9800E NEs, Jbase.img, Jsecu.img, Jadvrout.img and
Jos.img are supported.
• For OS 10K NEs, Ros.img, Reni.img are supported.
• The OS 9700E, OS 9800E, and OS 10K NE platforms must be fully synchronized
and certified.
• Target images must be loaded to the /flash/issu directory.
• Sufficient flash memory must be available for upgrade images.
• The CMM software build must be in the same major build tree branch, differing
only in the build number (for example, 6.4.1.*.R01)
• OS 9700E and OS 9800E NEs running an ‘R##’ build, such as 6.4.1.123.R01 do
not support ISSU patches. The NE must first be upgraded to an ‘S##’ build such
as 6.4.1.123.S01. This does not apply to OS 10K NE platforms.
Warning — An OmniSwitch may require a firmware upgrade before a
device software upgrade. To avoid a service outage, ensure that the
device firmware version supports the software upgrade. See the device
software Release Notes to obtain information about firmware and
software version compatibility.
Caution — Alcatel-Lucent recommends that you establish a physical
console session on the device that you need to upgrade. The console
session allows you to monitor the upgrade and recover the device in the
event of an upgrade failure.
