Physical NIC vmnic0 is up
To ensure the NIC's stay up even after the host reboots for Qlogic FastLinq QL41xxxx 10/25/40/50 GBE ethernet adapters
Rebooting the esxi host causes the Ethernet adapters to go down every time and we had to run the command esxcli network nic up -n vmnicX to get the interface up. This behavior is observed on the qedentv drivers running with lower qedentv driver < 3.0.x
Make sure the host is placed into maintenance mode and you do the firmware upgrade first before upgrading the driver.
To solve the issue schedule a maintenance activity and ensure to upgrade the firmware of the NIC adapters and driver version to latest version. Please refer the VMware HCL link to know the appropriate driver's and firmware's required for qedentv driverhttps://www.vmware.com/resources/compatibility/detail.php?deviceCategory=io&productid=45643&deviceCategory=io&details=1&partner=73&VID=1077&DID=8070&page=1&display_interval=10&sortColumn=Partner&sortOrder=AscAfter updating the driver to 3.10.23.1 and firmware to 8.37, please reboot the host.
