Thanks for your response.

Correct me if my understanding is wrong ? You mean ,From Centralized ESRS ,it should reachable to internet ,right ?

And FYI, I tested Network from Centralized ESRS under “Configuration” and network check and then click Run test  and all test are successfully (it’s reachable to EMC ESRS gateways).As we can see these warning from Unity storage devices

Hi Shankar,

Contract refresh requires direct internet access to support.emc.com/uemconnect.emc.com. It is normal for Centralized ESRS boxes to report as "Refresh failed". Unless you are ready to open ports, you can ignore this warning.

Contract information data is direct inquiry from the array. ESRS Gateway on the Centralized config is exclusively used only for "ESRS" communication.

You could try configuring a proxy server in the Unisphere settings

Thanks for your info,As i would like to know which ports need to open in order to fix this warning /to refresh of contract data from Unity since we don't have proxy server.

Hi,

So as discussed,

ESRS and support info are completely separate things.

ESRS centralized only works for ESRS, not support.

Have a look at these KBs:

https://support.emc.com/kb/485275

https://support.emc.com/kb/487022

I also suspect you may be running old Unity OE code? If this is the case please update to latest asap.

Thanks,

You can allow uemconnect.emc.com (port 80 and 443) and support.emc.com (port 443), also a DNS Server that can resolve this.

Thanks Andre for the given KB and info.

As per KB, verified all checks and looks good, except ports issue with 80 and 443. since 80 and 443 is not allowed outwards and to uemconnect.emc.com.Will take look into these ports access.

By the way, current Unity running with 4.1.0.9058043,Is this version has bug with regards  to this issue/error

Yes, so once those ports are sorted, you should be ok.

And there is an ETA for code upgrade to 4.1.2. I would be upgrading ASAP.

Thanks

Andre @ Dell EMC
