cisco 7k - unable to load the image

[rss01]

Hi All,

I have 2 N7k (C7702) to set up .
After getting console access to them ,I found out that both are stucked in the switch(boot)# prompt.
Probably they had PowerOn Auto Provisioning (POAP),don't remember if skip it or selecting something else.

Anyway ,here is the problem:

switch(boot)# load bootflash:n7700-s3-dk9.8.4.2.bin
switch is not yet ready to load the system sw
Unable to mount /mnt/pss, entering vshboot

So the next step was to try a different kickstart image to begin with.
Assigned an IP address and GW for mgmt0 and copying a new version to bootflash  - then,reboot,CTRL-C and from the loader> ,boot the new kickstart.
In the end,it didn't fix the problem,

switch(boot)# load bootflash:n7700-s3-dk9.8.4.7.bin
switch is not yet ready to load the system sw
Unable to mount /mnt/pss, entering vshboot

So for the 2nd switch ,I've decided to give it a try and remove everything.

switch(boot)# clear nvram
switch(boot)# init system 
switch(boot)# format bootflash:

Assigned an IP address and GW for mgmt0 (this time under the "loader>" prompt) and booting its kickstart directly from a server.

loader> boot tftp://x.x.x.x/n7700-s3-kickstart.8.4.7.bin,
ending up with:

Filesystem type is tftp, using whole disk
Boot failed

Error 9: Unknown boot failure

Any idea what the problem is in both of those cases?

Thanks,

you can find more details here https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/nx-os-software/216547-nxos-securely-erase-the-contents-of-th.html

1. Reload or power cycle the switch while connected via console.
   
   
2. While the switch is booting, use CTRL-C to break the switch into loader> prompt.
   
   
3. From the loader> prompt, enter cmdline recoverymode=1.  This stops the switch booting at the switch(boot)# prompt:
   
   

   loader > cmdline recoverymode=1 

4. Begin the boot procedure with boot bootflash:<nxos_filename.bin>.
   
   

   loader > boot bootflash:nxos.7.0.3.I7.8.bin

5. The switch boots to the switch(boot)# prompt.  At this prompt write, 0's to all blocks in nvram, except the license blocks, using clear nvram CLI as well as init system CLI.

   switch(boot)# clear nvram
   switch(boot)# init system 
   This command is going to erase your startup-config, licenses as well as the contents of your bootflash:.
   Do you want to continue? (y/n)  [n] y

6. Once step 5 is complete, reload the switch:
   
   

   switch(boot)# reload
   This command will reboot this supervisor module. (y/n) ? y

Thanks for feedback,

Actually by following this procedure I’m now here.

So after,

switch(boot)# clear nvram
switch(boot)# init system

and format bootflash: , I no longer have anything on bootflash anymore ,so when I’m trying to boot the kickstart image in loader> from a remote server ,I’m getting that error
