Introduction
This post covers setting up the aggregates, volumes,
qtrees, LUNs, igroups, post migration snapshots… all NetApp FAS controller steps
involved when migrating an FC SAN to NetApp. The script outlined here is written
with a specific scenario in mind, and here we are starting from a newly
installed NetApp FAS2240-4 HA pair after the initial setup script has been run.
This is Data ONTAP 7-Mode.

Beginnings
Firstly: if
you’ve run the NetApp DataCollector from http://synergy.netapp.com/disclaimer.htm,
imported the information into Synergy, and completed the design, much of this
script can be obtained as an output from Synergy.
Secondly:
copying and pasting commands into PuTTY doesn’t always go smoothly, a much
better method is to download/copy the script to your controller, and with CIFS
this is very easy:
FAS1&2> cifs shares
-add tmp /etc/tmp
FAS1&2> cifs access tmp root “Full Control”
FAS1&2> wrfile -a
/etc/usermap.cfg DOMAIN\USER1 => root
Then simply map a drive to tmp, copy the script over and
run with:
FAS1&2> source /etc/tmp/the_script
Note: From this
point, all the commands below will need to be run on both heads (with
modification for controller2)
