Error opening NVRAM on Cisco 3550

On a Cisco 3550 IOS switch. When I run the show configuration command, I get "error opening nvram" Or the device hangs. Show run works ok. What could be causing that problem?

Re: Error opening NVRAM on Cisco 3550

Hi ,

Checkout below options...

1. Enable 'service compress-config' to compress the configuration before 'write memory'.

This compressed config will take less nvram space, due to which nvram geometry will be

initialized correctly.

2.

a.) erase the nvram by write erase

b.) unconfigure some configs to fit the configs into nvram.

c.) Issue write memory

Repeat steps a, b, c until this error message vanish.

3. On platforms that support it, "boot config ..." can be used to save the

configuration to another file system other than nvram.

4. If the router has already been reloaded "write erase" should reinitialise

nvram and allow "write memory".

Cheers :) MSK

Do a "dir flash" and see how much space you have left there , you may be out of space and need to delete items like unneeded images etc..
