You should try to minimize IRQ sharing (specially between devices which should have different priority levels like an HBA and a NIC). # echo ::interrupts -d | mdb -k For more information on how to create the aggregation, check out dladm's man page (create-aggr command). > > I am familiar with ifconfig.

You should add all 3 addresses to /etc/hosts with different names. 1.2.3.4 host.domain host x.x.x.x host2.domain host2 y.y.y.y host3.domain host3 > 3.
