Trying to fetch IP address of the data mover using SMI-S in Celerra File simulator
Hi,
I am using Celerra File simulator which I used to create an NFS volume and expose it to vmware vc to create vms on it.
I am trying to get IP address of this configured datamover (cge0 and cge1 both are assigned ip addresses from unisphere ui). I am then trying to get all entities like (volume, storage pool and data mover) by using SMI-S provider already installed on the simulator.
I get data mover instance and then I try to use two different methods (shown below) to get to EthernetPort instance of datamover to get IP property but I get this exception --> "WBEMException: CIM_ERR_FAILED (A general error occurred that is not covered by a more specific error code. (com.emc.cmp.osls.api.meta.ClassDef.getInstances():919 C:ERROR_CLASS_SOFTWARE F:ERROR_FAMILY_FAILED R:805699596 X:ERROR_FLAG_TRANSIENT L:221 Connection cannot be established to the Data Mover server_3.))"
Any idea what this exception is?
two methods of getting EthernetPort
1. Get DataMover instance -> and then get ethernet port by this relationship -> "Celerra_SystemDevice_DMCS_DMEP" (as per UML diagram of SMIS programming guide)
2. Get DataMover instance -> Get NFSServer instance -> Get NFSProtocolEndPoint instance -> Get ethernet port by relationship -> "Celerra_DeviceSAPImplementation_DMEP_NFSPE". (as per UML of SMIS diagram programming guide)
Thanks very much for help.

Hi,
I did not put this info in the above question.
I have server_2 configured to cge0 and cge1 (connecting to eth1 and eth2) from command line of file simulator and then assigning correct IP address to both cge0 and 1 from the UI.
If I go to the Network-> and Devices I see this error. May be it is related to exception I am getting above.
"Connection cannot be established to data mover Server_3"
Thanks very much.

There is a 1DM and a 2DM version of the simulator - which one did you install?

Hi,
I installed 2 DM version. It has 4 GB memory assigned to the VM from OVA itself. I can see two data movers Server_2 and Server_3 when I do ./configure_nic server_ -l. (listing them)
May be my network configuration is wrong. What I have is eth0 (connected to external network so it gets IP address). I use this IP address to open unisphere UI.
then I have 2 nics (eth1 and eth2) that are connected to our storage network which doesn't have external IP. What I did is ./configure_nic server_2 -a eth1 and ... eth2 so cge0 maps to eth1 and cge1 maps to eth2.
Did not do this above step( -a part) for server_3. Is that a problem? What eth ports and cge ports should I connect server_3 to?
Thanks for ur help with this.
Update ::
when I run command /nas/bin/nas_server -info -all I get this.
name server_2 ; type = nas ; slot = 2 ; status defined = enabled ; status actual = online, active
name server_3 ; type = standby ; slot = 3 ; status defined = enabled ; status actual = slot_empty
When I try to run this command /nas/sbin/setup_slot -init 3
CRITICAL FAULT : Slot 3 not found or invalid!

Any help on how to enable server_3 in celerra would help solve the exception I am getting.
Thanks

server_3 is standby datamover, unless you explicitly turn it into an active one. When it's in standby mode, you can't communicate with it, it takes over server_2 identity (IP, shares, disk ..etc) during datamover failover.

Thanks for ur response. The problem is, while trying to get IP that I assigned to cge0 and cge1 on server_2 from unisphere UI, I wanted to get those IPs from program. (basically need to know the path of NFS volume I created)
The program is right now throwing exception as I have shown in first post above. That is the reason I was trying to enable server_3. Which doesn't work because I get CRITICAL FAULT : Slot 3 not found or invalid! when I run /nas/sbin/setup_slot -init 3.
May be it is a problem in the API that I am using that while getting EthernetPort instance of DataMover server_2, I am getting exception for server_3 not being available.
Thanks
