OnTap Simulator 8.1.1 no longer running on ESXi 5.1 free

rkeu — Mon, 29 Sep 2014 18:30:47 GMT

I'm the only one with this issue? After upgrade of my ESXi host to 5.1 the OnTap Simulator 8.1.1 no longer work. I only get the follwoing error:

Cannot open the disk '/vmfs/volumes/<id>/vsim-DOT811-7m/DataONTAP-sim.vmdk' or one of the snapshot disks it depends on.

The system cannot find the file specified

VMware ESX cannot find the virtual disk "/vmfs/volumes/<id>/vsim-DOT811-7m/DataONTAP-sim.vmdk". Verify the path is valid and try again.

Before the Update everything worked without any issue. The vmdk Files are there, it also not works if i manually assign those disk files. I have also never made any snapshots, this cannot be the problem.

A re-download of the Simulator files and add to the Host, get the same issue.

Same problem here. I also tried upgrading VM hardware but no success.

Ok, then let's hope NetApp is working on this issue.

Hi Roland,

I got it working! The trick is in the name of the disk itself. Here's how I got it working. I think step 4, 5 and 6 is more relevant. Thanks.

1. Install vmware-workstation on my desktop (version 9)

2. add netapp 8.1.1 ESX version (vsim-DOT811-7m-esx) as VM to my vmware-workstation

3. right click manage and change hardware compatibility to workstation 9,,,

4. right click settings -> select harddisk 4 -> click utitlies -> compact

5. export as OVF template

6. import this OVF template to ESX5.1 (from web client) giving it a new name ie. test1

7. power on!

Regards,

Chakrit

Hi Chakrit

Can you perhaps place the vmx file here, especially the Disk Part? And how are the Disk named now?

Hi Roland,

Sure thing,, but sadly to say it boots up and let me do the config but then kernel panic out. I'm out of ideas, sorry.

Ok, thanks for the Info. So we have to see how we can fix this issue.

stephent — Tue, 02 Oct 2012 19:30:46 GMT

I can confirm this behaviour. I just put esx 5.1 on my server at home and tried to get the 8.1.1 simulator working. It came back with exactly the error you are reporting.

Looks like a 5.1 compatible release is needed.

CCIE17603 — Fri, 05 Oct 2012 16:06:28 GMT

Everyone I have the fix. It's a VMWare issue. By default ESXi 5.1 does not load the the vmkernel multiextent module. See the KB Below.

http://kb.vmware.com/selfservice/search.do?cmd=displayKC&docType=kc&externalId=2036572&sliceId=1&docTypeID=DT_KB_1_1&dialogID=448358018&stateId=1%200%20448356307

The Fix: all you have to do is ssh into your host and run this command from the cli:

# vmkload_mod multiextent

The other stuff in this article didn't apply to me. All I had to do was run this command and my ONTAP Sims booted like usual, no issues. Unfortunately after a ESXi host reboot the multiextent module unloads and you have to perform this again to get your Sims to boot. If anyone can find a way to make this persistent with a switch or write a script that makes it load upon host reboot. I'm sure everyone would be very thankful.

This has certainly resolved the issue for me. Thank you.

Brilliant! Thank you! I'll give it a try.

Great. Thanks.

I had the same issue and it worked instantly after giving the

# vmkload_mod multiextent

command

To ensure that the "multiextent" module is present on every boot, you need to edit /etc/rc.local.d/local.sh and add a single line "vmkload_mod multiextent".

Re: OnTap Simulator 8.1.1 no longer running on ESXi 5.1 free

ckeith — Thu, 06 Dec 2012 20:30:04 GMT

Hmm, I'm having a problem getting ESXi 5.0.0 to even register the simulator. From vSphere pointing to vCenter I get the following error after trying to add the simulator to the inventory:

A general system error occurred:

The system returned an error.

Communication with the virtual machine might have been interrupted.

If I point the vSphere client to the actual ESX host it is able to add it to its inventory, but if I try and power it on the "action get canceled by a user" (or something like that) and it stops trying to power it on. Basically, I think it is vCenter trying to register it but fails so it stopped the ESX host from powering it on.

Any ideas?

Hello,

i had the same issue. What i did to fix it was to load vmkload_mod multiextent

and to use the Vcenter converter to convert the vsim-DOT812-7m into my vcenter.

It worked directly for me.

Hi there, i am also having this issue i have downloaded the 8.1.2 sim for ESXi from my NOW site,

-i have then used the ESXi shell to extract to relevant datastore on host,

-added vm to inventory

-using the # vmkload_mod multiextent in the shell i have ran this

-power on virtual machine and i then get this error...

is there a specific order i need to add the virtual machine etc? this happens on both 7mode sims and clustered ontap sims....

for info i am running vsphere esxi 5.1

Just removed sim from inventory and re added to no avail, same error around this DataONTAP-sim.vmdk file not being found when it is clearly in the datastore
