Description

Context
  • A server with 44 NICs fails to make available more than 8 of them running SmartOS.
  • Running a different OS (linux) makes all NICs available.
  • the box is a dual Xeon E5-2630L

Diagnosis
  • `prtconf -d` shows the 44 interfaces
  • `dladm show-phys `only shows 8 of them
  • `modinfo | grep apix` say apix MPv1.4 compatible
  • /var/adm/messages has no error/failure messages
  • For mdb -k -e '::interrupts' please see attached images
