[mhrahmanpt]

6450P10l switch is down and getting console of " ceritfied>kernel> " and not able to get configuration mode.. is it image issue. .how can i reimage from this mode...

You could try a USB stick (smaller than 2GB), that is recognized by ALU switches (try it on a workíng switch)
create a file (can be empty) named aossignature in /
create file system structure
/6450/working
/6450/certified

And copy the image files into both (you probably only need "/6450/certified" for that) directorys

This would enable the switch for disaster recovery, so plugin the USB stick an powercycle the switch and watch the console output

and , what's next .........

[devnull]

Just pluing the USB and powercycle the switch.
When observing the Console output you should see something like "disaster recovery in progress" and the switch should copy the files from /6450/certified to the switch.

If that does not help open a SR.

Don't do configration the switch?

?
No disaster recovery was introduced with support of USB (i think 6.4.3) on 6400/6850 and i think in some maintanace release train of 6.6.1

If the switch can not locate an image it should work with just plugging the USB in..

Why don't you just try, i don't think your switch works atm, so why wait?

I did it again and again and this is my console output

Hello,

you have to update the switch. This version is buggy. I had the same probelm. I think, its fixed since version 6.6.3 438 R01.

If you have problems to update the switch (can't write on flash), format the flash and make a usb disaster recovery.

I don't know if you have already solved your problem, but what you should do is:

Step 1)Prepare the an USB Pendisk (2GB or less) to recover your switch. Use the following steps
Step 1.1) Format an USB Pendrive (2GB or less) with FAT16 filesystem in your computer
Step 1.2) Create directories in USB Pen's filesystem
/6450
/6450/working
/6450/certified
Step 1.3) Download the switch firmware archive from Alcatel and extract all files, especially the *.img files, and copy them to /6450/certified directory in USB Pen's filesystem

Step 2) Boot the Switch and wait until reaches the fallback prompt with mentioned earlier, which is "Certified: [Kernel]->"
Step 3) Format the switch's flash executing
Certified: [Kernel]-> sysNewfs "/flash"

Step 4) Insert the USB Pen in the switch's USB port
Step 5) Power cycle the Switch and allow it to automatically copy the firmware from the USB Pendisk.

You can read more information from "OmniSwitch 6250/6450 Switch Management Guide", Chapter 5, in topic "Disaster Recovery Using USB".
