Firewall yes, more likely a routing problem with the network.Rob: Do make sure the cables are plugged in where you expect them to be. More than once I've had customers tell me they plugged into #1 Ethernet (ETH0 on the HMC) only to find out they really put it into #3 (Eth2) since the layout of the ports on the back of the newer HMCs are not always intuitive, and of course they don't read the label.--Jim OberholtzerAgile Technology ArchitectsOn 8/1/2017 8:50 AM, Tsvetan Marinov wrote:> Hi,>> It looks like a firewall issue, can you check the following requirements in> the document:> http://www-01.ibm.com/support/docview.wss?uid=nas8N1019111>> You can try to remove the server from connections and try to add it again,> sometimes it takes a while in order for the HMC to discover the server.
