There are two ways to do this.
1. Initialize all disk and using the 4a options
To get the 4a option do the following
a) Connect to console of the filer and Halt the system using halt command
b) Now say bye from CFE prompt
c) During the booting time you find the availability of Click Ctrl+C to get the Special boot menu
d) Now press Crtl+C (may be one or two times)
4) Select 4(a) options this will initialize all the disks ( Zero fill) and create an aggregate and root flexible volume for you
5) Once the initialization is done you will ask for the Setup
2.
a) Destroy all the aggregates and add the disks to the existing aggr0 (Root)
b) Now if you want to reset the configuration in priv set advanced (halt -c factory)
Method 1 will clean everything in the filer.You need to configure/setup everything from scratch. Also re-installation of Data ONTAP release
will be required to launch Filerview.
Method 2 Will clean configuration and keep the filer in Factory default mode. You can configure the filer using setup command. Less painful
compare with the method 1.
