We have SAP HANA Database installed on Lenovo Servers, with Mellanox 10G Cards. We want to upgrade current 1G copper link to 10G mellanox. We got Fiber ran to ports on servers, but server is showing “No Link Detected”. Mellanox drivers are showing loaded. Could someone please advise why it’s showing like that? and if we can fix it?
eth102 is mellanox, and connected to 10G switch port via Fiber:
