--- we could not enable a network interface 

root@server1:~# ipadm create-ip net11
ipadm: cannot create interface net11: Datalink does not exist

--- we implemented online pci card replacement procedure commands, but in fact we did not make a physical replacement.

hotplug disable PCIE5
# we did not run it
# cfgadm -c disconnect /SYS/RCSA/PCIE5

hotplug enable PCIE5
cfgadm -c connect /SYS/RCSA/PCIE5

---- then link became up
