OnTAP 8.1.2 simulator with ESXi 5.1 [ Edited ]

[#1]

Hi,

I wonder if OnTAP 8.1.2 simulator is supposed to work on ESXi 5.1 hypervisor?

I downloaded vsim-DOT812-7m-esx.tgz and followed the instructions provided of how to deploy it, the VM fails to start with the following:

..

Any ideas?

Hello,

if you're looking to evaluate Data ONTAP in VMware maybe just try this,

http://www.netapp.com/us/forms/ontap-test-drive.aspx

I havn't used the simulator in a really long time, but if you right click the VM and look at the hardware, I think one of those is actually meant for VM player or something. (I think!)

Here is the guide.

Hi,

Thanks for the link, judging by *.ova file extension I'd say that VMWare Player / ESXi template file. I'm going to try it.

However it says "Data ONTAP Edge 8.1.1 Evaluation" .. I'm not sure about the "Edge" bit. Is it "normal" OnTAP or something "special"?

I'm preparing an internal training for my colleagues and ideally need to have some working VM's over here.

Cheers,

Vladimir

Hi Vladimir,

the simulator relies on the VMware module multiextent which isn't loaded by default with ESXi 5.1:

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2036572

After loading the multiextent module you should be able to import the simulator, but you have to convert the disks like mentioned in the kb article since the module-load won't be persistent across reboots of the ESXi host.

Best regards,

Bernd

Hi Bernd,

Thanks a lot! I followed the KB and converted the default VM into the VMFS format, it works now.

Some more details:

1. Convert the default images as the KB suggests.

2. Start the VM and get to the point where OnTAP automatically reboot. not being able to find disks.

3. Click "CTRL+C" to get into "Maintenance menu".

4. Choose item 4. to initialize OnTAP.

Hi,

It's similar on DOT 8.2 in Clustered Ontap:

1. type vmkload_mod multiextent in the ESXi shell
2. boot VM
3. press "ctrl-c" when option arrives
4. go for option 4 to initialize all disks

Grtz,

Christian Smet

Search for:

# vmkload_mod multiextent

Disk changes made:

/vsim_esx-7m # vmkfstools -i DataONTAP-sim.vmdk DataONTAP-new-sim.vmdk -d thin

Destination disk format: VMFS thin-provisioned Cloning disk 'DataONTAP-sim.vmdk'... Clone: 100% done.

/vsim_esx-7m # mv DataONTAP-sim.vmdk DataONTAP-sim-old.vmdk

/vsim_esx-7m # mv DataONTAP-new-sim.vmdk DataONTAP-sim.vmdk

vsim_esx-7m # vmkload_mod -u multiextent

Module multiextent successfully unloaded VM powering up!

the easy and simple way is to use converter when transferring or uploading to ESXi or another virtualization is to use vmware converter to avoid these errors.

works for me..

Thank for this information. It helped a lot

Is it correct that I can delete the following files on the ESXi after converting the DataONTAP-sim.vmdk?

- all the DataONTAP-sXXX.vmdk files

- the original DataONTAP-sim.vmdk
