Error connecting vnxe to VSI

I installed the Unisphere and Navisphere CLI packages as well as the plugin, all seems to go well until i tried to add my vnxe to the unified storage management. 

Error:  Unable to connect to the UEM CLI, check the IP address (which has been verified as the management IP)

Did I need to do something on the vnx side to make this work?

TIA

Re: Error connecting vnxe to VSI

Is there firewall blocking IP package between your vCentre and storage SP?

Or you could attach your log message of this error, will try to find someone to look at it.

Re: Error connecting vnxe to VSI

This error is thrown because vnxe is not responding. So typically it should be a network issue.

Please double confirm that the management ip is accessible.

Meanwhile, could you please try to use uemcli directly following the steps outlined below to see if it gets a response:

1. Open cmd prompt window.

2. In cmd window, cd to the directory where your uemcli is installed (you can skip this step if you already set the windows PATH variable properly).

3. Input the following cmd :

      uemcli -d {mgmt_ip}  -u {username} -p {pwd} -sslPolicy accept /sys/soft/ver -type installed show

    In this command, please replace {mgmt_ip}/{username}/{pwd} with the corresponding info shown below:

         {mgmt_ip} - the management ip of your VNXe

         {username} - the name of the user for your VNXe system

         {pwd} - the password of the user

  Please paste the response of the command you get, then we can do further analysis based on your input, thanks!

Re: Error connecting vnxe to VSI

i have verified that there is no network routing or firewall issue preventing the vcenter from communicating with the management IP of the vnxe.  I ran the following cmd:     uemcli -d {mgmt_ip}  -u {username} -p {pwd} -sslPolicy accept /sys/soft/ver -type installed show and the result was:

Storage system address: 10.x.x.x
Storage system port: 443
HTTPS connection

Operation failed. Error code: 0x100000a
The system was unable to connect to the storage server. (Error Code:0x100000a)

I am able to establish a connection to the storage system address over port 443 however.

Re: Error connecting vnxe to VSI

This is odd, as the error you're recieving is designed to be returned when the ip is not connectable.

I have personally encountered the exact same problem, for my case it eventually turned out that the management ip for the vnxe has been changed.

So are you able to log on to unisphere GUI by typing the management ip into the address bar of your browser? Can you see the following GUI:

Re: Error connecting vnxe to VSI

Yes,  I can get to the GUI and am able to assign storage to hosts etc.  You mention that in your case the management IP had been changed.  That is the case here as well, durin the initial install the management IP was input incorrectly so it had to be changed.  Is there more than one reference to the old IP in the system configuration somewhere that may be the issue?

Re: Error connecting vnxe to VSI

As you guys talked so far, it seems that possibility of issues in VSI is cleared. Since the vnxe management ip is not connectable when directly using uemcli. We maybe need more help from uemcli/vxne team to assist on it.

Re: Error connecting vnxe to VSI

Did anyone here eventually find a fix for this?

I can't seem to get any historical performance metrics on the following queries:

"/metrics/value/hist -path sp.*.net.device.*.bytesInRate show -interval 60 -count 1",

"/metrics/value/hist -path sp.*.net.device.*.bytesOutRate show -interval 60 -count 1",

"/metrics/value/hist -path sp.*.net.device.*.pktsInRate show -interval 60 -count 1",

"/metrics/value/hist -path sp.*.net.device.*.pktsOutRate show -interval 60 -count 1"

Experiencing same error code:

Timestamp           |SP        |device          |Network  

                    |          |                |Out      

                    |          |                |Pkts/s

Operation failed. Error code: 0x100000a

The system was unable to connect to the storage server. (Error Code:0x100000a)
