Hi,

Does anyone know why I am unable to write new files to the NVRAM?

R7/FR_SWITCH#sh ver | i IOS
IOS (tm) 2500 Software (C2500-I-L), Version 12.1(3)T, RELEASE SOFTWARE
(fc1)

R7/FR_SWITCH#dir nvram:
Directory of nvram:/

1 -rw- 1923 <no date> startup-config
2 ---- 5 <no date> private-config

32762 bytes total (30839 bytes free)

R7/FR_SWITCH#copy start nvram:test
Destination filename [test]?
%Error opening nvram:test (No such file or directory)
R7/FR_SWITCH#

I have 2610XM's and 2611XM's that have no issue, its only my 2522 for
some reason and I can't figure out why.

Regards

Peter

I guess it's a limitation of the 2500 nvram: filesystem; my 2511 running
12.0(28) behaves
identically.

Ahh, that's a bit disappointing. I wonder if an IOS upgrade will help..
Hmm..

Remember that the 2500 series are run from flash routers - thus you
cannot copy a file to flash unless you boot down to boot loader

I would be very surprised if the nvram or flash filesystem behaviour
changes with newer images

Yeah but nvram (on the 2500) is separate from flash, and is of course writeable
(else how would "write mem" work?)

(But anyway, I did a quick case search now, and does turn out that you can
create a new file in nvram only if you aren't running from flash. Still can't
think quite why.)

Cheers,

Aaron
