FAILURE TO RECOVERY OS6450 from procedure

[dpaiva]

Hi,

In an attempt to update the 6450 switch I mistakenly copied the 6350 image files to the certified folder of the 6450 switch.
The boot was through the miniboot, after many attempts to recover the switch via USB (which I did not recognize), ZMODEM and XMODEM without success, I did the procedure (attached) that I found here on the forum for 6350, some commands did not work others yes .
But after doing some commands and restarting the switch I can't see the boot anymore through the teraterm or putty through the console ...

Some commands was that

setenv nandWriteFlag 7
6250 uboot>>nand scrub.chip
6250 uboot>> erase.chip (work)
6250 uboot>> start (not work)
6250 uboot>> usb 0 2000000 KF3bootselector.bin (not work)
6250 uboot>> erase 0 0x130000 (work)
6250 uboot>> write 2000000 0 0x130000 (work)
6250 uboot>> erase 0x200000 0x130000 (work)
6250 uboot>> write 2000000 0x200000 0x130000 (work)
6250 uboot>> usb 0 2000000 KF3diag.bin (not work)
6250 uboot>> erase 0x800000 0x1000000 (work)
6250 uboot>> write 2000000 0x800000 0x1000000 (work)
6250 uboot>>go 0xa10000 (work)
miniboot>"/uflash/kf3miniboot.bs","/boot/" (not work)
miniboot>cp "/uflash/6350/certified/*.img","/flash/certified" (not work)

after this comands and reboot i´stoped see

Please, how do I fix this? attached the file of this procedure that I did.

Thank you
Paiva.

do the disaster recovery for with the OS6450-image files KF*.img.
USB stick with folder 6450 - within 6450 the directory certified - and within certified the image files.
Than power on the switch with this stick.
Do not use a big stick - better is to use an older with max. 4GB (and FAT or FAT32).

Hi,

What happend? Did you find a solution.
I would love to hear a followup on this one because I am in the same position that the switch is completely out of reach through console port.

Thanks in advance

where do we get the img files?
i need the arrescue.img for a os 2260
thank you

[silvio]

@slaskaridis - please open a new article in the correct folder for the 2260.
With access to the myportal you can download the rescue-file there.

Hi,
I need to reinstall OS on Switch OS6450-P48.
I cannot access via Putty and the equipment does not generate any IP
could you show me how the file tree inside the flashdrive would look please?

[silvio]

/6450/certified/KF....img

[KGEVO]

/6450/certified/KF....img

no work.

need some .ini file in the flash drive root?
it looked like this on the USB:
\6450\
certified
OS6450_imgsha2sum
software.lsm

\6450\certified\
KFbase.img
KFeni.img
KFos.img
KFsecu.img

Is it correct this way? (I didn't find any information in the PDF Manual about mounting the USB boot to recover the System)

[silvio]

Please test the stick at an other (working) 6450. Insert the stick, usb enable, show usb statistic, ls /uflash etc.
If this isn't working you need to use another stick (or format this one again with FAT).
