Problem to create Centralized Monitors in VNX5200

After import Call_Home_Template_7.33.0.11 to VNX, i will try create Centralized Monitors but i can´t discovered ESRS Virtual Machine in step 6 and i ping VNX with success.

My steps:

1. Launch Unisphere Client and login the portal VNX system with Administrative credentials.

2. Go to Monitoring and Alerts > Notifications > Distributed Monitors .

3. Click SP A to display templates in use. Right click the template > Click Stop Using.

4. Repeat the same steps on SPB to remove call-home templates for SP B.

5. Switch to Centralized Monitors tab. If there is a centralized monitor, go to Step 8.

6. Click Configure > Right-click Portals > Click Add Portals > Go to Subnet to Add > Enter the first three octets of the IP for the Monitor Station (for example, if the Monitor Station uses 10.32.125.100, enter 10.32.125) ->  Click Scan > The monitor station will appear in the discovered system > Click the Monitor Station > Move it to Selected System > Click OK.

7. Right-click the Portal> Select Add Centralized Event Monitor > Enter the IP address of the Monitor Station > Click OK.

8. Select the centralized monitor and click the  Monitor System.

9. Select the VNX system to be monitored by this centralized monitor from the drop-down menu.

10. Right-click the Centralized Monitor > Click Select Global Template > Select the template from drop-down menu.

In this environment i have one IP Gateway Client and three VNX5200 in three different sites.

Anyone with the same problem can help me configure Call Home template in VNX5200?

Best Regards.
