Network Interface Card

Issue

  • Network port is showing as down on adapter. Example:
slot 3: Dual 40/100G Ethernet T62100-CR
    e3a MAC Address:    00:07:43:62:dc:30 (auto-100g_sr4-fd-up)
        QSFP Vendor:         FINISAR CORP
        QSFP Part Number:    332-00440
        QSFP Serial Number:  X5PBM36
    e3b MAC Address:    00:07:43:62:dc:38 (auto-unknown-fd-down)
        QSFP Vendor:
        QSFP Part Number:
        QSFP Serial Number:
  • The issue remains with an -up-admin false/true, port toggle.
  • The issue remains with a known working SFP.
    • But the same SFP in the "failed port" works in another network card port.
  • In case the port is for cluster connectivity, it fail to connect to up node making StorageFailOver giveback fail
