[c-nsp] Adventures while upgrading a dual sup-8 WS-C4510R+E

[Sebastian Beutel]

Dear List,

    i don't want to hold back the experience i made today while trying to
upgrade a 4510 shelf. Clearly the jump from 03.03.02 to 03.06.05 was too
far. What i didn't expected was this message that showed up on the console
of the second sup when the new ios booted there:

----<snip>---------------------------------------------------------------

#    #    ##    #####   #    #    #    #    #   ####
#    #   #  #   #    #  ##   #    #    ##   #  #    #
#    #  #    #  #    #  # #  #    #    # #  #  #
# ## #  ######  #####   #  # #    #    #  # #  #  ###
##  ##  #    #  #   #   #   ##    #    #   ##  #    #
#    #  #    #  #    #  #    #    #    #    #   ####

The following environment variable(s) are set.  Setting these
environment variables may cause the system to behave unpredictably.
        "DontShipDisableThermalShutdown"
Use 'clear platform environment variable unsupported' to clear these
variables.

Never heard of such a thing. And I definitely don't want my chassis to melt
should our air condition refuse to work some day. So when i finaly finished
the update i tried the suggested command and guess what:

----<snip>---------------------------------------------------------------

dno19-y1-s1#clear platform environment variable unsupported
No unsupported environment variables found

----<snap>---------------------------------------------------------------

Even though i like beautifull ascii art and also variable names that start
with "DontShip" i feel slightly scared having such a thing running on our
production Switches. Has anyone ever seen something like that and knows how
that is to be appraised?

Best,
   Sebastian.
