What I did was completely wipe out the netapp and reinstall 6.1.2R3. We are reracking our qa lab so I figured it would be a good time to let our Microsoft admin get to learn how to install a netapp, etc. So its a fresh install and before we put our databases back on it I did a sysstat and noticed the activity. I've let it run overnight so maybe the memory scrubs are finished and that was the activity.
I am hoping at some point we can upgrade the netapps we have to the 960's and I can maybe get to attend Netapp training to get some inside knowledge of the boxes.
We are running on a nonexistant budget and its tough supporting all this gear without maintenance contracts.

Disk Scrubs? Did you just upgrade?

Would anybody know why I have disk writes occurring on my netapp when it is completely disconnected from the network. It is doing memory scrubs, but would this cause writes to the disk?
Here is what sysstat looks like. As you can see there isn't any nfs, cifs or http activity. On my other filers that are hooked up to a network the Disk writes go to zero when there isn't any activity.
