Catalyst 3550 refuses to reload!
 

Hello,

i get the following message if i type "reload" :

----
SIGNATURE-3-NOT_ABLE_TO_PROCESS: %ERROR: Not able to process Signature
in flash:.
%SIGNATURE-3-ABORT_OPER: %ERROR: Aborting reload.
----

ios is :c3550-ipservices-mz.122-25.SEC2

Furthermore there seems to be a problem with the nvram "dir nvram" shows:

----
Directory of nvram:/

%Error opening nvram:/ (Function not implemented)

----

Any suggestions?

I think the only way to solve this issue is to manually power-cycle the
switch!?


Thanks,

Karsten

%SIGNATURE-3-NOT_ABLE_TO_PROCESS : %ERROR: Not able to process
Signature in [chars].

Hello, i saw this documentation page too. But what does it mean??
I originally posted:

SIGNATURE-3-NOT_ABLE_TO_PROCESS: %ERROR: Not able to process Signature
in flash:.
^^
The error wasn't linked to a specific file.

I also checked the ios image located on the flash with the "verify"
command, it was o.k.

Furthermore i formatted the whole flash and downloaded a fresh image
from cisco.com and copied it to the flash.

But all there things didn't solv the problem: The above error-message
occured each time i typed in the "reload" command.

Perhaps there was a problem with the process handling the filesystems on
the switch. As stated before, i could't access the nvram: filesystem
properly.

Perhaps you can provide some additional background info.

Is this the first time you have trued to reload this switch with this
IOS image

Has the image been changed recently, etc

Re: Catalyst 3550 refuses to reload!
 

dir nvram: may not be a valid command on a 3550

what does dir flash: show ?

Unfortunately I don't believe power-cycling the switch will fix the
problem.
If the IOS you are running has the capability to "format nvram", you
should try that.
If it doesn't, you'll need to replace the switch. It doesn't happen
often, but sometimes the NVRAM does go bad.


Good Luck

The image was changed and rebooted 1 week ago. There was no reboot after
this change.

i think, it`s a valid command:

----
Switch#dir nvram:
Directory of nvram:/

382 -rw- 0 <no date> startup-config
383 ---- 0 <no date> private-config

393216 bytes total (393164 bytes free)

The output of the flash filesystems looked good, no problem, some space
free...

The ios didn't allow me to format the nvram. Because

SIGNATURE-3-NOT_ABLE_TO_PROCESS: %ERROR: Not able to process Signature
in flash:.

referenced to the flash filesystem, i formatted the flash and copied a
new Image on it. But the above message appeared after each reload-try!

Now, i drove to the rack and power-cycled the switch. Now everything is
fine again! But i think, it was a very strange error and luckily no
customers were affected...

After you power-cycled the switch you could issue the reload command
without getting the error message?

I would open a case with the Cisco TAC and find out if this is a known
problem.

I would also determine if their is a newer IOS image for the switch.
