Great post! As a smallish shop we can't afford a lab unit, so we end up testing on the least critical DM of our production NS704G. With the simulator, we'll at least be able to do some basic feature testing. I'm really looking forward to setting up SRM using the simulator...



Loved the post. Wished I had something like this for the centera I was fiddling with.

Any shot you can do the AVE one next? I have to get 1.1 live ASAP.

Alan Warwick

Thanks Chad. I've been trying to setup up an SRM lab here at the office and this modified Sim will make it happen.

Two ESX servers on a real NS22, running one of the simulators, going to to another ESX server attached to an NS601G/CX400 running the other simulator. Each simulator will present iSCSI LUNs to the host they are running on. Looks a bit like Perpetual Motion or Renewable Energy!

Mike Cu

Fantastic Fantastic follow up post!!!

Finally something for us small IT shop personnel to get our hands on to see how the big boys do it.

A community blog site needs setting up ASAP.

However my children and wife would officially like to complain.
The summer vacation is now going out of the window!

any idea how till 202? I wondering on the ways to add storage to the Celerra. I know I have the 5GB and 15GB built in and I can add storage with NFS (Looks difficult). Can I add vmdks to the VM and make it see them as Clariion LUNs?

Chad Sakac

Alan - just for you, I'm going to try to pop out the 201 tomorrow am. It's easy, you can just present more VMDK volumes to the VM, and with a little config jiggery-pokery, get more storage. Only thing easier would be a real Celerra :-)

Chad Sakac

John - I'm going to try to get AVE 1.1 ASAP. Do me a favor and if you've got some pull with the AVE team, remind them they have a great product, and should let me go hog-wild :-)

Attila Bognar

Hi Chad,

first: thank you for your blog.

I installed/configured the sim following your post, I have two questions:

- /etc/hosts seems to be incorrect (hostname -f does not work correctly). You type: csprod csprod.esxdomain.local csprod
Shouldn't it be: csprod.esxdomain.local csprod
(the localhost line has the same problem)

- why are you setting and exporting NAS_DB=/nas just before rebooting?

And a tip: you can easily and quickly logout with CTRL-D.


ps: the sound card support is funny :-)

Stan Dorsett

Great tutorial Chad. Any idea when you'll release the next in this series? Specifically I'm looking for the "config jiggery-pokery" to allow my simulator to see added vmdk files.

Earl Hinkle

This is great, especially creating all the other products in VM's for test dev environments. This will definitely give EMC a leg up in the storage area.

Earl Hinkle

Are they going to come up with a sim for the CX line of products? ie cx3 and cx4?

Doug Baer

Great stuff. I've got replication setup and it seems to work, however, the nas_replicate command hangs and trying to list the replications in the GUI does the same.

I'm replicating to a real NS20 and the commands work from that side. Any ideas about where I can look to get more information on what nas_replicate is trying to do so I can try to trace the problem? CPU isn't spiking, Memory use is minimal... I can't find a bottleneck.

Incidentally, this command is used by the Celerra SRA, so testing with SRM doesn't work for me, either.

Mike Kolcun

Thanks very much for this post. Very very helpful!

Mike Kolcun


I was wondering about monitoring the Celerra (simulator) via SNMP. I've been able to use the RFC1213 MIB to get some basic data, but haven't been able to find another mib which might provide more.

I found a MIB at http://www.oidview.com/mibs/1139/EMC-CELERRA.html but it did not seem to work.

Any suggestions? Thanks a lot

Murali Raju

Hi Chad,
Thanks for this great appliance! I thought I'd address a small issue in regards to VMware Tools. I had a little bit of trouble upgrading VMware Tools on the Celerra VSA and ran into some issues with building vmxnet.

I put up a new blog and my first crack on a video upgrading VMware Tools on the Celerra VSA or Linux in general :)



Murali Raju


Hi again

I was wondering if this it is normal that this the workstation template iéported as Version 4 i have only eth0 and eth1, no matter what in tried
If I enter ifconfig eth2, it shows that the card is here but as down. Bring it to UP do not change anything : No IP even thought eth0 and eth1 work like a charm. More over at start eth0 and eth1 are seen to be brought on line but not eth2

Tried it as bridged and host only : same result

Tried on workstation 6, 6.5 and player very exact same result

Not tried on ESX Thought

Any thought and idea ?

Best regards, Marin


Hold On

Putting Eth2 UP dans using netconfig -d strait afterwards seems to do the trick... Weird
Any way iany idea or comment on this behaviors is welcomed :-)



Hi (again)
Just one question : is the celerra in a VM is supposed to work with other iSCSI initiator than the ESX one ? The installation goes without a glitsh following the very efficient vids... But a the very last moment using the MS initiator as "quick test" it fails.
No matter the the config (bridget, host only.. ) when I try to connect to the portal (step one of the MS client) I get the message : "Add Target : Target Error".One more thing : so far i don't have any problem with other ISCSI Target Ie : Free NAS, Open filer....)
The strange thing is the ISCSI IP port is reachable from the iscsi initiator so there is no firewall problem there. I Just did the very precise installation a iscsi target creation, ie no chap or ip sec (nothing more, nothing less). Any thought or did this already happen to someone ?
Net step i will try on the ESXi server.. .and keep you informed

Best regards


How to install the Celerra simulator on a linux machine..?

Paul Wegiel

WOW - this stuff is amazing.
I finally managed to install and configure the Celerra simulator in my SRM lab in the basement. I replaced the SAN I have been using so far with Celerra and it works great.

Chad, I want to thank you for providing this awesome learning resource!!!


Just curious..do you all use VSA for production or just demo purpose. the lowend storage is like 5000 and this vsa cost 4000..what is the selling point?


Thanks for all you do Chad! I'm looking for the procedure to delete an iSCSI LUN. Using the SIM I created 2 iSCSI LUNs backed by 1 target. Connected two ESX hosts to them. Now I'm trying to delete 1 of the LUNs but I'm getting complaints that the 2 ESX IQN's are still connected to the LUN/Target. I don't want to delete the other target because the other LUN has data on it. I registered with the EMC forums yesterday to look for an answer but haven't received my login credentials yet possibly due to registering with a new company name. The EMC forums appear to be not browsable without an active account.

Thanks, Jas


I did entire configuration as per steps but I am getting error while creating NFS in step 8
NFS Does not support MOUNT version 3 over TCP

Any help in this matter will get me closer to resolution.
Any other way to configure this?

I just need to use shares as test.
Thanks in advance.


anyone able to sucessfully start the OneDM Simulator from Powerlink with Workstation 7 ?

I keep getting coredumps with NOT_IMPLMENTED pollVMX.c errors


Eric Moore

Thanks so much for the wonderful work.

Have you details/instructions on setting this up for a single NIC? I have the EMC Celerra Simulator Guide however, it still isn't quite clear how to use this with one NIC.

All the best,

Phil Lawrence

I'm going to probably not be that popular on this one but this does seem to be a whole load of work to get a simulator working to test an interface and capabilities of a storage appliance. Is there not an easier way to get it working???

I've downloaded and played with the Sun S7000 simulator and it took me a few minutes to download 500MB and NOT 1.5GB); I can run it in VMware player or Virtual Box and it took me about 5 minutes to get it up and running.

I get iSCSI, CIFS, NFS, HTTP, WebDAV and a whole bunch of other stuff in the S7000 simulator, I can update to the latest firmware and can do a whole bunch of things with it (just like the real version) like snapshots, replication, shares, alerts, analytics (you have to see what this can do for you...) etc., etc.



TBone A

ESXi 4 and the lastest VSA. I do not have an ETH2 in the VSA? Can someone help me out here? I'm a bit lost.

Philip Leighton


I have the same issue - no ETH2 - I have also posted oon Celerra forums about this and in the other blog post. You are not alone !! :)

(And I also agree somewhat with Phil above - getting this up and running is a bit cumbersome)




Where you able to get pass the NFS Does not support MOUNT version 3 over TCP error? I'm encountering the same issue.


I found a little mistake in the init_storageID script.
In the lower bit there is a while loop and it increases WAIT instead of WAITS.

I was discovering this as the script took very long to complete.
Stopping it with CTRL-C missed a needed step in the script and I was not able to create a file system.


thanks for the info on celerra.
I would like to ask is there a way i can get CISCO MDS fabric manager simulator???
It would be a great help if anybody can mail me or provide me with the link to download one.

Hi Chad,
Thanks for all the information here. I was wondering when we could get 201 and 301 series to get our hands even more dirtier.

Brad Brunner

Having issues getting it to boot past blackbird, on Workstation 7. Do we need to run converter on it, so it works with later version of VMWorkstation?


Hi Chad, Your information has been priceless in setting up my Celerra VM SIM (I am/was purely a Windows Guy). The only problem I have run into is after creating a CIFS server, I cannot get it to join to the Domain. I have set the date and time manually for the Server_2 DM and when I run server_date server_2 from the GUI CLI it returns the proper date/time now but the GUI (which for some reason does not allow the option to change it(its fixed)) does not show the correct time (4 hours off). I am not sure if that is the problem as the logs state " SMB: 3: dns_DCLookup::process:: Unable to get any DC from DNS for domain op.corp.lab
2010-08-24 13:23:44: DNS: 3: 1: Unable to connect to name server 172.xx.xxx.64 : Protocol not available

DNS is configured properly and I am able to ping from my DM IP to the DC (and vice versa)so I am not sure if it is the Clock skew in the GUI or the something else? Is there a reason the date and time is fixed for the DM but not for the Control Station Properties?

Andy Lawrence

Can you show how to get iSCSI working in the EMC Unisphere with the version 6 of the simulator?


Hi Chad,

I cannot figure out how to download Celerra Virtual appliance.
Can you let me know how to download the file?

Thank You,


hi can you help me with the celera simulator download

Chad Sakac

@Robert, @BHA - it's pretty straightforward (unless a link is busted). If you look at the top, this post fans out from a "master link". Follow that master link, and you'll find the latest Celerra download.


Google "UBER Celerra VSA"....



How to solve the error after a fresh setup saying "Box Monitor Recover slot 3 failed."

Thanks in advance,


Hi Bah,

You can download the latest simulator from nick's website.



Cheap Chanel Bags

frustration and regret that I didn't pay closer attention in geometry class.
It appears that she's only made thirteen movie and/or television appearances during her career, the last one something called Buddy Boy in 1999. My exhaustive internet research turned up little more than squat.


I am using latest simulator with two data movers - downloaded from power link. I am able to bind CGE0 & CGE1 to eth0 & eth1 respectively. I can create a data mover interface using CGE0. I can ping from this interface to outside server like NTP, my test servers and vice versa. Not a showstopper issue but a wired message is scrolling in my vm console. Specially whenever any traffic is hitting this interface. "Protocol 0000 is buggy, dev eth0"


Just got to this article by google after the "MOUNT version 3 over TCP error".

I found the problem: This error message appears if you try to connect to the managment interface of the VNX. After you create (or before) a share / mount etc. you need to create a new interface (Settings -> Network -> Interface -> Create).

After i created the interface it worked directly for me.



I had the same problem; "Protocol 0000 is buggy, dev eth0".

Cause: Appears when there is a conflict.

Here is the fix:

create an interface on "cge1 mapped to eth1" and not "cge0 mapped to eth0". Use the interface for creating CIFS server etc.

Illustration: (interface new on cge1 mapped to eth1)

new protocol=IP device=cge1
inet= netmask= broadcast=
UP, ethernet, mtu=1500, vlan=0, macaddr=0:c:29:6f:71:98

"cge0 mapped to eth0" is used for the internal communication between control station and datamover. When we create an interface on this physical device and use it for CIFS; it creates a conflict.

illustration: (default interfaces e131 & e130 for internal comm.)

el31 protocol=IP device=el31
inet= netmask= broadcast=
UP, ethernet, mtu=1500, vlan=0, macaddr=44:41:52:54:0:6 netname=localhost

el30 protocol=IP device=el30
inet= netmask= broadcast=
UP, ethernet, mtu=1500, vlan=0, macaddr=44:41:52:54:0:5 netname=localhost

Thank you.

Virtual Pilot 3d Review

Most folks are doing well if they just RTFM, but I thought a little "hand-crafted walkthrough" might help others. The standard documentation is geared towards VMware Workstation, which is the officially supported target (BTW, you don't need to ask, we're making ESX OVF a standard package :-), so some people stumbled a bit when trying to use it with ESX.

I have problem when i want to join a domain during the creation of CIFS server. What should be done to go through.
