INTRODUCTION

I have created this document as it has been a great experience to me working with the Data Ontap

simulator. It is very real, building the simulator as it is explained on this guide, will let you practice

exporting LUN via iSCSI, creating shares, working with snapshots, it is almost an all functional virtualized

storage.

If you want to learn some storage fundamentals or NetApp fundamentals, gain some practice on the

Data OnTap CLI or FilerView, this will help you to set up a very real, working, and all functional lab.

So, let’s cook….

CONCEPTS

Some stuff you need to get familiar to understand this guide if you have never worked with storage

solutions. If you are already familiar with Storage concepts or with NetApp technologies don’t bother

reading this section.

Storage fundamentals, it would be great first you to have some idea of what a storage box is, different

vendors, such as EMC, Hitachi and IBM, NetApp is just one more of them. And what is a SAN, and SAN

Connectivity, for real storage environments this is the cornerstone, it is a physical layer composed by FC

cables, FC switches and directors, even we are not going to virtualize a SAN (since it is not possible), and

we are going to use iSCSI instead, it would be great you to read some about other Storage Vendors and

most of all about SAN and SAN Connectivity, so you can get an idea the way it is in the real world, and

get a better understanding on the gaps between the real world and this simulator.

Filer, is the way NetApp call’s their storage boxes, doesn’t care if they are used only NAS (CIFS and NFS)

or only for LUN Mapping, or both, they call their boxes, filers.

FilerView, is the admin portal for the storage, an alternative for the CLI.

Aggregate, Volume, qtree, LUN, Snapshots, this is what you can do with the disks inside your storage,

how to arrange them to reach a technical objective. For example, you arrange your physical disks into

Aggregates, but the aggregates are composed by raid groups and these ones by physical disks,

understand the loop? Of course, an Aggregate can have more than one raid group. Once your aggregate

is created, you can create volumes inside of it, and inside these volumes you can create shares, qtrees,

luns or snapshots.

But as this is not a NetApp administration guide, I’m going to stop here talking about this, and just say

these are key concepts to understand in order to be able to operate you NetApp simulated Filer, if you

want to read more you can do it at NetApp’s NOW site, http://now.netapp.com.

Finally, I’ve mentioned this couple of times at this point, synthetic hardware, this nothing else but the

hardware you add to your VM.

INGREDIENTS

What you will need for your recipe and where to get it.

VMWARE SERVER 2



Virtualization software, this is my choice, you can change it for any other that supports a Linux operating

system, mounting ISO images in synthetic CD hardware of your VM and more than one Ethernet

synthetic interface in your VM. VMWare Server 2 it is free, and you can get it from:

http://downloads.vmware.com/d/info/datacenter_downloads/vmware_server/2_0 just register and

download.

UBUNTU SERVER 10.04

This was also my choice, even it is documented by NetApp that is fully supported by their simulator, I

guess you can run another Linux flavor you like. It is also free, at the moment this document was written

10.04 was the latest version available. Download from: http://www.ubuntu.com/server/get-

ubuntu/download no need registering, just select 32 bits Server ISO and download it.

UBUNTU ADDITIONAL PACKAGES

Some packages you will need, as I choose Ubuntu as the base system I used apt in order to get the

packages, but if you choose another Linux flavor you might have to download the sources or

precompiled binaries and make them on you system.

• open-iscsi (necessary for mounting iSCSI exported LUNs from your virtualized storage)

• lsscsi (just to check when an iSCSI LUN has been mapped to the system)

• expect (necessary only for running the simulator in background)

• vim (just because I like it more than vim-tiny)

For Ubuntu choosers, all of them available from the Lucid repository.

DATA ONTAP SIMULATOR 7.3.4

The master piece, the simulator itself, you can get it from http://now.netapp.com (for this you must be

a NetApp’s member, partner or customer, as the company I work for is, I’ve been able to download it,

anyway there is a registration form available on the site, I haven’t tried if registering on through that

form makes also the download available).

You will get an ISO image file from where you will get all you need for your simulator. At the time this

document was written, Data Ontap 8 version had already been released but as it is for 64 bits I preferred

to keep working on 7.3.4. Also this new version seems is does not need to run on top a VM, of course

the ISO for this version is much bigger than for 7.3.4.

NETAPP LICENSES

Data Ontap simulator includes all the licenses or the products and features available in your filer, such as

Flex Clone, Snapmirror, Syncmirror, iSCSI, CIFs, NFS, and so on. You can find them inside the ISO image,

under ./docs/license_keys.htm

MODEL

First of all, let’s take a quick view of what we are going to build and its layers (on the following diagram

I’m going to include only the relevant layers).



lun snaps

vol0 Volume (vol1)

aggr0 Aggregate (aggr1)

Data Ontap ns0

iSCSI

Ubuntu

VM

eth0 eth1

Data Ontap root Aggregate and Volume

Starting from bottom to top, our VM, a common VM configured to run a Linux OS with 2 virtual NICs.

We will need 2 because by definition, the Data Ontap simulator, binds its network interface/s to physical

interfaces (actually this is a synthetic NIC but the simulator doesn’t know that). And once the ns0

interface from the storage is attached to the physical one, the server where the simulator is running it

won’t be able to access the storage through that interface, and as we are going to map luns though iSCSI

a second interface will help us to do so.

The VM NICs can be bridged, NAT, or host only connections to your hosting machine, that’s your call,

and also based on what your Virtualization software allows you. As we are going to download some

packages with apt, I recommend you to set at least one of them as bridged or NAT.

Moving forward, the OS, Ubuntu is this case, we will install Ubuntu Server with the Virtual Machine

mode, so a minimal system is installed, no graphical interface, no unneeded packages, no wasted space.

Finally the Data Ontap simulator and the open-iSCSI package for LUN Mappings. We are talking about

this much in depth in the following sections.

RECIPE

Here you will find the steps for the implementation of the VM and the Simulator, on some parts I’ll show

a high level description on what should be done, such as in the OS installation process, the guide is

meant to let you setup your lab to learn some storage and NetApp not Linux, internet is plenty of

documents to answer your questions and I’ll be pleased to answer any consult.

Also the storage once installed will be simple configured, no clustering, no virtual interfaces, you can

play with that if you want, but I’m not going to show that here.

1. Create your VM with 2 NICs, 1 configured as NAT or bridged at least. I recommend you to use

between 256 and 512 MB for RAM and 8 GB for disks will be ok.

2. Install Ubuntu server as minimal virtual machine mode, during the first screen, ater selecting

language, press F4 and select the installation mode.

3. Follow the installation steps for the OS.

4. Take note of which network interface will you select as primary when the installation prompts.

5. When prompted about server functions to install, select openSSH and Samba, for remote

administration and filesharing with your desktop, these functions are not required pieces for

the puzzle but might make your life easy working with the simulator.



6. Once Ubuntu is installed I recommend you to take a snapshot of the VM, just in case something

goes wrong you do not have to run the installation all over again.

7. If installed openSSH configure it to accept connections over any of the network interfaces.

8. Edit /etc/network/interfaces to include your second interface. And if you want fix IPs for both

interfaces.

9. Restart networking daemon.

10. Install the following packages:

a. vim ; Run: apt-get install vim

b. open-iscsi ; Run: apt-get install open-iscsi

c. expect ; Run: apt-get install expect

d. lsscsi ; Run: apt-get install lsscsi

11. Configure iSCSI daemon to start automatically. Edit /etc/iscsi/iscsid.conf under Startup Settings,

change the startup mode to automatic.

12. Mount the Data Ontap simulator CD and run the installation script ./setup.sh. Following steps

(13 to 26 ) show the options given during the setup.sh script execution. Text between brackets

shows the default option, if you press return without entering any character this will be the

configured option. For these steps, comments will be in bold to make difference between

installation prompts and comments.

50. Once loged in as root you will be taken to the Data Ontap prompt “your storage name”> in my

case Ontap01>. Now you can start playing with your storage!

INSTALLING LICENSES

For most things we want to do here, we need to install some licenses, from your linux machine mount

the CD image and browse to ./doc and open the file named license_keys.htm. To install the licenses it is

really simple, we can do it through CLI or via FilerView. For our next objective we will need to install

iSCSI license, so go to the file, grab the code and run the following command in the Data Ontap CLI:

license add <code>

Repeat the procedure for every product or feature you want to enable. To get a summary on the

licenses installed just run the license command.

PROVISIONING A LUN THROUGH ISCSI

At this point your simulator should be up and running and you should have all disks as spares, to

accomplish this objective what we need to now is:

• Create a new Aggregate.

• Create a volume inside the Aggregate.

• Create a LUN inside the volume.

• Create an Initiator group and add our iSCSI address.

• Map the lun and the initiator group.

• Log in from the OS to the storage over iSCSI and discover the LUN.

• Make a FS inside the new disk and mount it.



• Keep playing with your storage!

I’m going to describe how to do this through the CLI, but you might want to do it through the FilerView

all options are available from any of these interfaces.

So, as we already cooked, let’s decorate the plate…

Creating a new aggregate

First of all, as I mentioned in the concepts section, we know disks are arranged into raid groups, and

aggregates are composed by raid groups. First of all, lets check the status of our disks.

Ontap01>sysconfig –r

You will get an output with the details on the physical disks and how are they arranged in through the

different aggregates. (If no aggregate was created only aggr0, the root aggregate will be shown an all

the other disks will be shown as spares).

Ontap01>aggr create aggr_tst -r 8 -t raid4 16@16m

This command will create an aggregate called aggr_tst with a raid group size of 8 with only 1 disk of

parity per raid group (raid 4) and will include 16 disks of 16 MBs each. (So it will create 2 raid groups

with 8 disks each, but only 7 will be usable since each raid group has 1 disk or parity).

Creating a volume inside the aggregate

Now the aggregate is created, check the space on it:

ontap01> df -h -A aggr_tst

Aggregate total used avail capacity

aggr_tst 191MB 80KB 191MB 0%

aggr_tst/.snapshot 10MB 0MB 10MB 0%

There are 10MB (5%) reserved for aggregate snapshots as we won’t take any snapshot from the

aggregate let’s claim that space:

ontap01> snap reserve -A aggr_tst 0

ontap01> df -h -A aggr_tst

Aggregate total used avail capacity

aggr_tst 201MB 80KB 201MB 0%

aggr_tst/.snapshot 0TB 0TB 0TB ---%

Now we’ve got all the space for us, let’s create a 100MB volume inside this aggregate:

ontap01> vol create vol_tst aggr_tst 100m

This command will create a 100MB volume named vol_tst inside the aggregate aggr_tst. So, the volume

is created, let’s check the space on it:

ontap01> df -h vol_tst

Filesystem total used avail capacity Mounted on

/vol/vol_tst/ 80MB 88KB 79MB 0% /vol/vol_tst/

/vol/vol_tst/.snapshot 20MB 0MB 20MB 0% /vol/vol_tst/.snapshot



Again we see space reserved for snapshots, we might want to take snapshots of this volume, so let’s

keep it, and create a LUN inside this volume.

Creating the LUN

Just run the following command:

ontap01> lun create -s 50m -t linux /vol/vol_tst/lun_tst

ontap01> lun show

/vol/vol_tst/lun_tst 50m (52428800) (r/w, online)

And the LUN is created. The lun create command includes the size of the lun (of course it can’t be bigger

than the volume where it is located), the type o OS which will access that LUN and finally the path

where you want to store it inside your filer.

Creating the iSCSI initiator group

First of all, on the storage side, check the iSCSI service is running:

ontap01> iscsi status

iSCSI service is running

In order to create the initiator group, you first must know the initiator’s iSCSI node name, go to the

Linux machine and read the content of /etc/iscsi/initiatorname.iscsi file:

InitiatorName=iqn.1993-08.org.debian:01:58cad98ae9c6

Then, create the initiator group with the igroup command:

ontap01> igroup create -i -t linux Initiators_tst

ontap01> igroup show

Initiators_tst (iSCSI) (ostype: linux):

About the create parameter or igoup command, you must specify it is an iScsi initiator goup type (-i

option) and the the host type and the group name. As you can see, it has been created but it’s empty,

let’s add the node name of the server.

ontap01> igroup add Initiators_tst iqn.1993-08.org.debian:01:58cad98ae9c6

ontap01> igroup show

Initiators_tst (iSCSI) (ostype: linux):

iqn.1993-08.org.debian:01:58cad98ae9c6 (not logged in)

Now, we need to map the LUN to the initiator group.

Mapping the LUN to the initiator group

Run the following command:

ontap01> lun map /vol/vol_tst/lun_tst Initiators_tst 1

and the mapping is done. You indicate which LUN to which group and which id will be set to the LUN

being mapped.

Discovering the LUN on the server’s side



At this point our storage is presenting the LUN via iSCSI to the server, now the server must run the

necessary steps in order to discover the LUN.

simulator:/$ lsscsi

[1:0:0:0] cd/dvd NECVMWar VMware IDE CDR10 1.00 /dev/sr0

[2:0:0:0] disk VMware, VMware Virtual S 1.0 /dev/sda

As you see, we only have the cdrom device and the disk where the OS is installed. Let’s discover the

iSCSI target:

simulator:/# iscsiadm -m discovery -t st -p 192.168.233.131

192.168.233.131:3260,1000 iqn.1992-08.com.netapp:sn.99923498

Now check or SCSI devices, just to keep a pre discovery view

simulator:/# lsscsi



Now restart the iSCSI service:

simulator:/# /etc/init.d/open-iscsi restart

* Disconnecting iSCSI targets [ OK ]

* Stopping iSCSI initiator service [ OK ]

* Starting iSCSI initiator service iscsid [ OK ]

ln: target `/lib/init/rw/sendsigs.omit.d/' is not a directory: No such file or directory

* Setting up iSCSI targets [ OK ]

Finally, list SCSI devices again:

root@simulator:/# lsscsi



[3:0:0:1] disk NETAPP LUN 7340 /dev/sdb

Creating an FS inside the LUN

Run fdisk and create a new partition inside the LUN and then format the partition.

Run: fdisk /dev/sdb, create the partition and write the partition table to the disk.

Then run mkfs.ext4 (this is just another one of my choices), Run: mkfs.ext4 /dev/sdb1

Finally mount the partition, Run: mount /dev/sdb1 /mnt.



APENDIX A: INSTALLING A CLUSTERED SIMULATOR

This document originally described how to build the simulator as a single node, but the simulator also

support’s clustered mode. This appendix describes how to install the Data Ontap simulator in cluster

mode.

When you run setup.sh script it is not much different from installing the simulator in single mode. Using

as reference the step numbers from the ‘Recipe’ section:

• Step 13: Would you like to install as a cluster? [no]: yes

After setup completes, and if you decided to install under standard directory /sim, you will have two

directories within /sim, node1 and node2, and inside of these directories, you will find the same scripts

and files you would find over /sim one a single node installation. Browse down to /sim/node1 and

execute runsim.sh, there are some key configurations, let’s review all the inputs required, and include

some comments on the relevant ones when talking about clustering:

Selection (1-2)? [1]: 1


The default name for this CIFS server is 'NODE1'.

Would you like to change this name? [n]:

Data ONTAP CIFS services support four styles of user

authentication.

Choose the one from the list below that best suits your

situation.

user accounts

(4) /etc/passwd and/or NIS/LDAP authentication

Selection (1-4)? [1]: 4

What is the name of the Workgroup? [WORKGROUP]:

Once it is operational, open a second ssh session to the server hosting the simulator, and browse down

to /sim/node2 and execute runsim.sh script, same configuration sequence as in node1 will be executed:

Please enter the new hostname []: node2

Do you want to enable IPv6? [n]:

Do you want to configure virtual network interfaces? [n]:

(2) Windows NT 4 domain authentication (Windows NT

or Active Directory domains)

(3) Windows Workgroup authentication using the filer's

local user accounts

(4) /etc/passwd and/or NIS/LDAP authentication

Selection (1-4)? [1]: 4

What is the name of the Workgroup? [WORKGROUP]:

At this point you should have both nodes running, login to both of them and add the cluster license as

indicated in section ‘Installing Licenses’ of this document.

After installing the license in both nodes, reboot them using reboot command. Once they have closed,

run again the runsim.sh script to start both nodes.

Once both nodes are up, in any of them run the cf status command to ensure clustering is enabled. If it

is disabled run cf enable command, running it on any of the nodes will enable it for the cluster, voila!

You have a clustered simulator.

Let’s take a look to the simulated physical configuration, node1 will be the owner of the shelves, they

will be connected under the adapter you selected during installation, in my case, v0. Partner will access

these shelves via v4 adapter. Then node2 has 1 shelf with 2 disks (mailbox) in v0 which will be accessible

via v4 port in in node1.

I’m Hernán J. Larrea, an IT engineer with 8 years of experience in the field. I decided to address my

career in Wintel technologies, specially Active Directory, Backup and Recovery environments, Storage

solutions and a little programming in .NET.

Most of the times when I write I try to write things I believe will become useful to others going through

the same or similar path I’ve traveled and I would have liked to find a document like this one.

If you want to know more about me, I invite you to visit my personal website

http://www.hernanjlarrea.com.ar or my blog at http://blog.hernanjlarrea.com.ar and if you want to

email me, you can do it at [email protected]
