Hi, all,

we just bought two refurbished Catalyst 6500 switches
which work fine except one minor problem.

One of the switches sticks at the rom monitor, when
powered on or reloaded. The error message is

Autoboot: failed, BOOT string is empty

Now I know that I could point the switch to boot from
a particular image like this

boot system flash <name of image>

But I'd rather have these rom mon environment variables
removed completely, instead of set to a specific value,
so the switch will always boot the first image it finds.

I didn't find a way to clear these variables - neither
from IOS (tried no boot system ...) nor from rom mon.

Shortly, what I want is this:

core2#show bootvar
BOOT variable does not exist
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102

instead of this:

core1#sh bootvar
BOOT variable =
CONFIG_FILE variable =
BOOTLDR variable =
Configuration register is 0x2102


Any hints on how to achieve this? The first output is from
the switch that boots just fine without an explicit image
specification.


Thanks,
Patrick

Thanks. Obviously I threw the wrong keywords at the search box.
Of course I know that everything is on CCO

Kind regards,
Patrick

That one is for CatOS - I run IOS.

Still searching ...

no boot system flashxxxx.bin worked on my 2950,s (in my lab) which also
run ios,then reload. I was upgrading to an ios that supported rspt pvst and
mst .Make sure there is only one ios on the switch though.
