Symptoms

"ib" devices are found missing when a host running Solaris 10 is rebooted.  The host has an infiniband HCA.  This HCA is linked to infiniband switch (nm2-36P or nm2-Gateway).  The host is rebooted at a time when there is no master subnet manager in the infiniband network.  The "dladm show-dev" output on the Solaris host does not show any infiniband devices after reboot when they should be there.
