I upgraded the IOS today (uBR7100) to ubr7100-boot-mz.123-21a.BC3.bin. Everything seemed to perform fine, I changed the boot system line in the config, it restarted, and now when the reload command is issued the following was noted:
Warning: Attempting to overwrite an NVRAM configuration written
by a full system image. This bootstrap software does not support
the full configuration command set. If you perform this command now,
some configuration commands may be lost.
Overwrite the previous NVRAM configuration?[confirm]n
No action taken because command was not confirmed
Proceed with reload? [confirm]
Also a strange thing is that the hostname should show LAB>
but it shows LAB(boot)>
and no matter what we change the hostname too the (boot) stays. So if we changed it to dude...the screen would say dude(boot)>
I have attached a sh ver, sh run, and the restart.
