A random inspiration for turning off the firewall solved the issue where I could not connect with the MDSM, and it is working now.
I have a MD3200i that is being repurposed from one server to another, a PowerEdge 410. The old server was running RHEL5 and the setup was straightforward and worked well for years. Setting up the new server is not so straightforward. I've tried the DELL_MDSS_Consolidated_RDVD_6_5_0_1.iso on the new server, a CentOS 7 box, and it's been nothing but weird. When the server reboots after the installation, the server can ping the array's iSCSI port (I only have a single path setup on this, and am trying to manage it on the in-band connection), but it cannot either manage or mount the array. When it gets weird is when I run a Windows 2012 R2 VM via KVM with bridged networking on the server, and put the MDSS software on the VM, I have complete control of the array, and can mount it in the VM. This means the hardware is working, but the configuration is not.I backed out the mapping and the host definitions, and remade them to point to the PE410 server, and this is what I get: [truncated as this goes on for minutes, Ctl-C out of it] So it looks like it is logging in and trying to make a session, but it isn't attaching right, because it never shows up as a drive in either the logs or in fdisk. I've been trying a million things, but at this point I'm just confused, and am hoping someone here has a clue they can loan me on how to troubleshoot this further.
