Supervisor Engines !!! One more question [7:50279] posted 07/31/2002
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]

Hi Group
I  have to upgrade IOS in bootflash: (for MSFC2, 6509)
But I can not erase the old version.
    - Delete bootflash:    command can apply but not take effect .
Image file still stay in bootflash (of course I didn't try to erase the boot
    - Copy tftp bootflash:  command doesn't have erase old image option.

I'm now booting the route processor from tftp server, but my customer didn't
like this solution.

The bootflash is protected from deleting ? rite ?
Anyone have experience with this situation.

Thank you in advance
