Can't TFTP to Cisco 2900XL Switch Flash image is corrupt

pndoyleuk

Hi My 2900xl image is corrupt, the switch can't load a proper image so it boots to a switch: prompt
I run flash_init command
then the load_helper command
dir the flash, I have no image files,
then I try to copy tftp to flash. I all ways get the same error, please have a look....

flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 3612672
flashfs[0]: Bytes used: 1536
flashfs[0]: Bytes available: 3611136
flashfs[0]: flashfs fsck took 2 seconds.
...done Initializing Flash.
Boot Sector Filesystem (bs:) installed, fsid: 3
Parameter Block Filesystem (pb:) installed, fsid: 4
Loading "flash:new_image"...flash:new_image: no such file or directory

Error loading "flash:new_image"

Interrupt within 5 seconds to abort boot process.
Boot process failed...

The system is unable to boot automatically. The BOOT
environment variable needs to be set to a bootable
image.
when I load a new image I get the following message?

switch:
switch: BB0BB0
Unknown cmd: BB0BB0
switch: BB0BB0BB0BB0BB0


if I try to copy tftp flash
I get the following error

I think your going to have to connect via console cable and delete that flash image and replace it with another.

If it say it's corrupt there is prolly nothing you can do.

How do I delete the Flash, I do have a console cable, when I tried to delete the flash before I get permission denied:
I think thta's because I only have the (switch:
prompt?
Any other way around that.
Thanks

Loading "flash:new_image"...flash:new_image: no such file or directory

WAIT!

I know of no Cisco IOS that is called "new image". You need to specify the correct image to load.

Console connect to the switch, lets say your switch is called Switch1.

First you type 'enable' to enter the priv mode.

Then see the e.g below.

Switch1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch1(config)#boot system flash:c3620-jk9o3s-mz.122-7a.bin
Switch1(config)#boot system rom
Switch1(config)#end

Just to warn you I have no idea how your old IOS is configure, it may be passworded it may be not. If it is your going to have to reset the password which is hassle.

tbh I would google this and find a decent guide. I really have to be in front of a box to remember this correctly.

If you can get the IOS to load up, just erase the configs in the NVRAM. Reboot the Switch and it should go into auto configure mode.

when you get to the switch: prompt, type "dir" and press enter. this will give you a list of all the files on the flash filesystem. One of them should end in ".bin", and this is the file you need to boot the system up from the rom monitor. You can do this using something like the following command:

switch: boot c2900XL-hs-mz-112.8.12-SA6.bin

obviously, you need to replace the "c2900XL-hs-mz-112.8.12-SA6.bin" filename with whatever file is on your flash.

if this doesn't work, or if there is no file in the flash directory ending in ".bin", then you need to execute the recovery procedure in http://www.cisco.com/en/US/products/hw/switches/ps607/products_tech_note09186a0080094955.shtml
