Managed to resolve this eventually. Was unable initially to configure the storage array due to the age of the SC version installed.  The Enterprise Management software available for download was too new to support the age of the installation. Dell Support were able to provide me with an earlier version and advise that the client alone was not able to create the server to array mappings on  its own.  It was required to install the data collector software on a server, log into the collector with the client and then configure the collector to log into the storage. All up and running now.
Hi, I have two Dell R630 servers attached to a SCv 2020 storage array. The servers each have a single 12Gbps SAS HBA external with two ports.  The storage has dual, four port controllers. Server 1 HBA is connected to port 1 on each controller.  Server 2 is connected to port 2 on each controller.   I have tried with several Dell EMC customized versions of ESXi and in each case the first server works fine.  It sees the storage, datastores etc. with no issues. The second server, when attached to the storage, takes forever both to install ESXi and also to boot when eventually installed. It does see the storage and datastores in a limited fashion but shows zero capacity, provisioned and free space.   Could someone please advise on how a system comprising of these components should be configured? Thank you
