I have a 3750 stack of 4 switches that was installed about 2 years ago. Recently I was doing some work on the switch and realized that I am unable to save the config. I amobviously concerned that if the power fails or the switch reboots I will be reconfiguring it and that is not something I am interested in doing! Any help would be appreciated.
Here is the error that I am receiving:
switch#copy run startup-config
Destination filename [startup-config]?
Building configuration...
nv_done: unable to open "flash:/config.text.new"
nv_done: unable to open "flash:/private-config.text.new"
nv_done: unable to open "flash:/multiple-fs.new"[OK]

Looks like IOS version is at a later release. Is there a way to tell if it is the hardware?
Hi Brad,
It ain't hardware. It's the software you are running. 12.2(52)SE is a very, very buggy code.
One more thing, you have a sub-directory called "update". You may need to delete this otherwise you will not be able to upgrade the IOS of the switch (in the stack).

Hi,
What is you SW version? please post "sh flash:" output.
There is a similar bug fixed in 12.2(50)SE1 and later releases, so if you are on older release, I suggest to upgrade:
CSCsq24610 write memory error after power-off new member in auto-upgrading
Also, this could be caused by a flash HW issues.
Kind Regards,
Ivan

Hmm...I will investigate the code option. I have to figure out how to get it downloaded as some reason CISCO decided that I don't have privileges to the IOS anymore...Thanks for the heads up on the update folder I will give it a shot and reply about the results.
Any John, yes, I definitely have it backed up - every Monday I add it to my weekly backups - thanks for the heads up though!

Mate,
before anything goes wrong make sure you have a copy of the config.
use a tftf server.

Check which switch is the master and issue a write memory once your are working from the master of the stack.

I have done the command from the stack master and it gives me that error.
Apparently it looks like I can download the IP base images but not the Universal. What is the difference between these two and would I want to avoid one or the other?

No not really.
the universal image has al the feature in it that you need to enable with a new licensing system while a normal 12.2.44 IOS for example is just as excellent as the universal.using the 12.2.48 and 12.2.5x no universal i have built a 90+ L3 switch infrastructure with no one issues for more than 4 years... and it is still working fine....

it will be better to save the config to TFTP server , if the router will crash you loss your "backup"

As it turns out, rebooting the switch did the trick. I had to save the config to a tftp server, reload it and reconfigure. Once I did that I could save the config and edit the flash. I still need to get the code updated but it shouldn't be an issue now.
