Can't add ONTAP simulator host to DFM server

Hi all,

I have configured clustered ONTAP simulator after opening virtual machine (downloaded from NetApp site) in VMware workstation - configured Network Adapter to use NAT, created cluster and assigned 192.168.40.1 IP Address to it, created aggregate, lif and volumes.

I am trying to add host from DFM server installed on another machine using the host IP where I have the virtual machine with clustered ONTAP, but it can't recognize the IP and gives error with timeout.

Can you give me a hint what I might done wrong or incomplete?

Regards,

Hasmik

Re: Can't add ONTAP simulator host to DFM server

I have a clustered Ontap simulator running on VMware Workstation.  I've always used bridged network adapter instead of NAT, though and I've never had any problems accessing them from System Manager or DFM.  Maybe you could try that?

Re: Can't add ONTAP simulator host to DFM server

I have tried that too and that also didn't work

Could you please tell, when you used bridged network adapter, did your VM get public IP? Did you use that IP to connect from DFM?

Re: Can't add ONTAP simulator host to DFM server

The installation guide states that in c-mode (and bridged), static IP has to be used...

- Bridged and Custom: Virtual network interface vmnet0 is set to bridged and all other interfaces used by Simulate ONTAP are set to either host-only or custom.

If the virtual network interface vmnet0 is set as bridged, then you can use the physical Ethernet port of your laptop to access all volumes created and mounted by using Data ONTAP. This works only if the IP addresses and subnet are static in clustered Data ONTAP, or if 7-Mode operations support DHCP.

Make sure you assign valid IP addresses to each node and to the cluster ip address.  Here are examples from two simulated nodes:

From simulated node 1:

san-4netappsim12-clu::> network interface show

            Logical    Status     Network            Current       Current Is

Make sure you can ping the node ip addresses and the cluster ip address:

Once you are able to ping the cluster IP you should be able to add it to System Manager.  You will also be able to add the cluster ip to dfm (see below):

C:\Windows\system32>dfm cluster add -U ezamora -P xxxxxxxx 10.10.202.4

Added snmp credentials with

        addr: 10.10.202.4, prefix length: 32, prefsnmpVersion: 3, authProtocol:

MD5, hostLogin: ezamora

Added host san-4netappsim12.xxxxx.com (71927).

Hope this helps.

Re: Can't add ONTAP simulator host to DFM server

Thank you very much for your help.

I really had something mixed with IP addresses. Now it's resolved, thanks a lot.

But I still cannot add cluster in DFM server.

I am able to add cluster in the OnCommand System manager which is installed on my local machine where I have cluster node VMs, but I fail to add it on DFM server running in another machine. Here is the error log:

where 10.26.128.251 is my cluster's IP address

I guess still I have something incomplete in my setup.

I would be very grateful if you could assist here.

Regards,

Hasmik

Re: Can't add ONTAP simulator host to DFM server

It looks like you haven't enabled or set up snmp yet.  You can enable and setup snmp through the System Manager GUI or in cli, do:

options snmp.enable to see the setting and to enable/disable snmp.  You can use snmp ? to show the snmp commands to set up your snmp settings and community.

Re: Can't add ONTAP simulator host to DFM server

I have it, but maybe it's wrong?

Thanks,

Hasmik

Re: Can't add ONTAP simulator host to DFM server

And I also set snmp on in cluster :

But still getting the same error on DFM server adding cluster

Re: Can't add ONTAP simulator host to DFM server

Please attach screenshot of "snmp" command (just snmp then hit Enter) from cluster CLI.  Also, are you able to ping the cluster ip from the dfm server?

Re: Can't add ONTAP simulator host to DFM server

Here you are:

And also I am able to ping from DFM server to my cluster:

Thanks a lot for your support,
