Updating DATA ONTAP Version

You need to have a Administrator access to the filer,

Before upgrading Data ONTAP, monitor CPU and disk utilization for 30 seconds by entering
the following command at the console of each storage controller:
sysstat -c 10 -x 3

The values in the CPU and Disk Utilization columns are strongly recommended not to exceed 50%
for all ten measurements reported. Ensure that no additional load is added to the storage
system until the upgrade completes.

Ensure all SnapDrive for Windows clients are running one of the supported versions.

Download the DATA ONTAP version from http://mysupport.netapp.com/NOW/cgi-bin/software/ and select your Netapp filer Model click on Go!

 NOTE : If you are performing a Data ONTAP NDU (or backout), you must perform this
step on both nodes before performing the takeover and giveback steps.
