NetApp Controller Scripts Overview for a DTA2800 FC SAN Migration

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)

## SETTING UP AGGREGATES ##
###########################

# Here were have SAS and Flashpool (SATA + SSD) aggregates
# Creating SAS aggregate
aggr create aggr_cont1_450sas -B 64 -t raid_dp -T SAS -r 11 22

# Moving the root vol off SATA (root vol cannot be in a Flashpool!)
vol create newrootvol -s volume aggr_cont1_450sas 162g
ndmpd on
ndmpcopy /vol/vol0 /vol/newrootvol
vol options newrootvol root
reboot

## REBOOTS!!! ##

# Destroy old root vol and rename new
vol offline vol0
vol destroy vol0
vol rename newrootvol vol0

# Configure Flashpool
aggr rename aggr0 aggr_cont1_flashpool
aggr add aggr_cont1_flashpool 5@847
aggr options aggr_cont1_flashpool hybrid_enabled on
aggr add aggr_cont1_flashpool -T SSD 3
