The service manual includes a task for hotplugging PCIe cards from a server running Oracle Solaris 10 or 11 OS.
Workaround
The commands in this procedure temporarily disable the network. Before starting this procedure, you must be connected to the system using either a serial connection, a terminal or emulator connected directly to the host, or using Oracle ILOM RKVM.
Check if Automatic NCP is enabled.
Enter the command:
netadm list | grep Automatic
If it is enabled, you should see:
ncp Automatic online
If Automatic NCP is enabled, switch to manual mode. Enter the command:
netadm enable —p ncp DefaultFixed
