DNS TimeOut in ICW for 2x PS 500T

Hello,

I am configuring 2 Powerstore 500T for a customer, in 2 different sites.
During ICW I set all required details, and when validating, I get this message

"Issue: Specified dns server does not pass pro

tocol level validation checks (status is timeout). (0xE0E700400001)."
The thing is I am also configuring servers(ESXis) and I plugged the mgmt of esxi on the Powerstore cluster ports and the resolve fine to their gateway and DNS/NTP servers.
VLAN is the same, gateway is the same, Any idea what could be the problem?
There is no firewalling/ACL in the interVLAN networks...


Thanks... :-/

Hello @DELL-Sam L​ 

I have solved this issue by switching to access/untagged on all cluster ports on our switch config.
I have deployed other Powerstore appliances with tagged cluster ports and cluster validation went fine...
Anyway, both appliances are now up & running.

Hello Julien A.

Are the physical systems at the site that they will be living at or are they currently at a different location?

@DELL-Sam L​ Hello,
Yes the appliances are at their final location.
I have tried with 2 DNS Servers, 1 DNS Server, also about the syntax for mask, I tried both '24' and '255.255.255.0' but none of them has helped...

Hello Julien A.

Which ports on your PS 500T are you using, as it seems like their might be a cabling issue?
