C6000 MSFC2 boot error

[jmprats]

Hi, after reloading a Catalyst  6009, MSFC2 boots in ROMmon. I've tried to boot the image from rommon  but i receive the following message:

"Environment checksum in NVRAM failed.

Bus Error exception"

What does it mean?

What can i do?

does it look a hardware or software error?

Thanks

I've tried to reset the BOOT and BOOTLDR variables from rommon:

>BOOT=

>BOOTLDR=

>confreg 0x0

>sync

Then it warns "Environment checksum in NVRAM failed"

>reset

The MSFC restart with the error:

"ROMMon NVRAM area is corrupted. Initialize the area to default values"

I think it looks a hardware error, true?

or  can i format nvram, or copy the ios image or something like that?

Hi,

This could be a hardware issue. I tracked a few cases and it all led to the replacement of the SUP/MSFC. However,

you can use " priv " command in the rommon mode to enter the "priviledge" mode and you should be able to delete the

the whole NVRAM config/files. Once done try booting it again and see if it can load with the image.

HTH,

In the MSFC2 rommon priv mode i don't have option to delete or format NVRAM.

Which command can i use?
