NetApp ONTAP Simulator and ESX Server

Hi! I’m trying to get the Netapp Simulator working in a Vmware Workstation running RHEL 3 on a Windows XP host. I get a whole load of messages when executing runsim.sh :

“Disk v4.40 Shelf ? Bay ? [NETAPP VD-1000MB-FZ-520 0042] S/N [18084922] has no valid labels. It will be taken out of service to prevent possible data loss.”

Later when I try to aggregate the disks I get a message indicating that there are no disks available, so I guess this is a result of the runsim.sh failures.

Have you seen this before? I’m lost for ideas!

Thanks - Paul.

I get the same problem. I ended up rebuiling the Simulator but I again faced the same issue. Is something different needs to be done when we are installing in a VM as compared to installing on a physical workstation ?

Thanks in advance.

I’ve gotten the following to work, I’ve then zero’d the disks.

>priv set diag
*>disk unfail -s v1.19

Is there an easy way to make the promiscuous mode setting permanent other than tweaking with init scripts on the vmware host?

Have you tried installing the Netapp Simulator onto your macbook pro
1) native osx +simulator
2) vmware +linux +simulator
3) Parallels +linuix +simulator

I’d love to know as the vmware simulator for mac is still in beta and runs slow because its also debugging so was wondering if you’d tried it with parallels at all?

cheers

TIP!
After you create extra disks for your simulator.
execuute these steps to get rid of disk fail messages:
>priv set diag
*>disk unfail -s v4.19 (where v4.19 is your disk)
Repeat for each disk to recover it. When they are all unfailed, follow with:
*>disk zero spares

FYI - in ESX server 3.0 you can just enable promiscous mode in the Virtual Infrastructure Client, under the vswitch properties,security. This is handy, because I’m sure folks use the ONTAP sim and the Celerra simulators the way I do, with vswitches with no NICs (internal only).

I have been building this on a host-only network under Workstation 6.02 for Linux, so it’ll be completely portable. So far, I have an AD 2003 DC (vm) serving up all the centralized services on the host-only network, a Centos 5.1 VM running the NetApp OnTap Simulator v7.23 providing multiprotocol CIFS/NFS for unified home directories while using AD/Kerberos for authentication and LDAP for user/group storage, and a couple of client VM’s (WinXP and Centos 5.1). Can’t get write permissions on the home export using autofs, so the users get “/” as home. Anyone have any ideas how I might implement this? I’d be thankful…

Hi,

I am Newbie for ESX serevr. I have a 7.2.3 netapp simulator. I created a iSCSI lun on the netapp. I then detect it from the ESX server and created the VM on the LUN. I then try to suspend the VM on the LUN . It fails with an error saying “General system error occured Can not suspend the VM” I then copy the VM to local disk on the ESX server and suspend happens succesfully. Am I doing some wrong setting on the LUN ? LUN protocol is set to “VMWARE”
I wouldbe thankful if you can help me on the same.

Regards,

Athreya

am running Unbutu Linux. Here is the output from ifconfig -a

Every time I try to run runsim.sh the error is

PANIC: pf: write error

This failure was probably caused by having your network interface down or an invalid interface. Re-run setup.sh and choose a different interface or fix the one you have chosen.
root@simulator-host1:/# /sim/runsim.sh

Please help here.

Just a follow up question.
Do you need to have 2 physical nic cards in order to run the simulator. I have on my ESX server 1 nic and 1 vswitch with multiple Virtual Machine groups. I assume that should be fine. Let me know what am i missing

Hi,

Is there a way to increase the size of the disks on the ontap simulator?

Thanks

can anyone of expert here share the simulator with me please…. i’m not d netapp customer or partner. Thanks in advanced.

Hi

I get this problem almost everytime when i run the simulator. The simuator starts up fine but then after running for 3 -5 minutes it crashes giving the below error message.

I am running simulator on FC4 machine and i have tried it on virtual machines with Rhel3 / 4 but it gives the same proble,

Oct 16 22:28:34 ukadmserv01 kernel: maytag.L[7079]: segfault at 1071 ip 09448f30 sp 9946bd98 error 4 in maytag.L[8048000+1b03000]

Can someone please point me how to fix this one.

Hi, we used to be a NetApp partner, but due to cost we no longer have a NetApp filer, this may change in the near future, i am pro NetApp and if I can demonstrate to our Directors that we could make money with a NetApp and my current Vmware project then they may invest again.

I would like to use the NetApp simulator for a vmware development project i am working on. Can anyone confirm if it has the same API as the official hardware?

And could anyone provide me with a copy of the simulator for development purposes?

Many thanks

Kevin Walker

I do not know esx that well (yet) but thanks for your tip regarding the Ontap connectivity.

THANKS!

for the guy that wants a copy of the simulator:

(Note from Scott: I removed the URL because I can’t sanction the distribution of software in violation of the guidelines set forth by the vendor. Sorry!)

I am almost ready setting up a SRM in a Box configuration with the netapp simulator and esx. You can read about it on http://www.tendam.info. Within a few days i will publish a complete step by step document. stay tuned

Hi ted, feel free to email if you can offer any advice about ontap development.
