I read this from the 'NetApp Support Owner’s Manual':
*The Storage Controller’s serial number can be found in one of two ways:
1. Using the CLI run sysconfig –a.The serial number is listed towards the top of the output. (First option is not applicable here) 2. Physically locate the serial number on the Storage Controller. Most models have a sticker on the back listing the serial number. Some models, like the FAS3000, list the serial number on the front underneath the bdiezel.
I think a KB is worth on this, some examples with pictures for locating serial number on differnet model series. This helps especially when the filer is right out of the box and not yet powered up. I could not locate any article on this.
