6880 booting issue

Hi
I ran into some issues with a pair of 6880s booting. I racked up 2 c6880-X-LE switches and done the following:

 

  •  powered on both switches
  •  copied latest ios c6880x-ipservicesk9-mz.SPA.152-1.SY6.bin to both switches (verified md5 of ios before copying)
  • changed bootvar and reloaded ok with new ios on both switches
  •  deleted old ios and reload again ok to confirm new ios boot
  •  done a wr erase and reloaded
  •  both switches then booted "Governator Boot Rom :Upgradable Region"

 

I logged the switch booting into "Governator Boot Rom :Upgradable Region" - see attached. Once booted, the console had an "SP5>" prompt. When I typed ? for help the console displayed a number of TAC looking commands (also in attached output).

 

I reloaded a switch and broke into ROMMOM. Before making any changes, the output of "set" in ROMMOM looked like:


RJ45_CONSOLE=0

TFTP_MACADDR=0:2A:10:60:CE:80?=0

LOG_PREFIX_VERSION=1

BSI=0

RANDOM_NUM=1057632312

BOOT=

RET_2_RTS=11:02:40 UTC Fri Apr 13 2018

RET_2_RCALTS=1523617360


The output of confreg showed:

 

Configuration Summary
   (Virtual Configuration Register: 0x2102)

enabled are:
 [ 0 ] load rom after netboot fails
 [ 1 ] console baud: 9600
 boot: ...... image specified by the boot system commands or default to: cisco2-Governator


When I tried to view the contents of the bootdisk I got the following:

rommon 2 > dev
Devices in device table:
        id  name
 bootdisk:  Internal flash drive
    disk0:  External USB drive 0
rommon 3 > dir bootdisk:
Please reset before continuing

 

When I tried to boot from tftp image I got the following (I could ping ok between the switch and tftp server after using the set commands):

rommon 5 > boot tftp://10.1.1.100/c6880x-ipservicesk9-mz.SPA.152-1.SY6.bin
Please reset before booting

 

I then tried the following:

BOOT=bootdisk:c6880x-ipservicesk9-mz.SPA.152-1.SY6.bin
confreg 0x2102
sync
reset

 

Now the switches boot up ok. I've set up a few 6880s before with no issue. I'm assuming this was user error on my part. Can anyone tell me why the switches booted they way they did and why ROMMON wouldn't let me view bootdisk:?

 

I'm working on getting these switches on contract so that I can contact TAC but was hoping someone could throw some light on this.

 

Thanks
Andy

Post the complete output to the command "dir".

The box does not go into Rommon mode, in no way gives code 0x4unnamed.png

During the boot-up cycle, smash Ctrl + Break keys.
