I have two HP servers which have a total of 10 Ethernet ports each, both running RHEL 5.7. I need to make sure that Ethernet ports are mapped to the same devices in Linux on both systems (see below) because these servers must be identical (the second box is a drop-in replacement in case the first system fails).
The ethernet ports on the first system are mapped as follows:
Device Port eth0 Intel Dual Port Card, Port 1 (Rightmost Port) eth1 Dual, Port 2 eth2 Intel Quad Port Card, Port 1 (Leftmost Port) eth3 Quad, Port 2 eth4 Quad, Port 3 eth5 Quad, Port 4 eth6 Onboard, Port 1 (Network is connected here) eth7 Onboard, Port 2 eth8 Onboard, Port 3 eth9 Onboard, Port 4
But after installing RHEL on the 2nd system I have:
Device Port eth0 Onboard, Port 1 eth1 Onboard, Port 2 eth2 Onboard, Port 3 eth3 Onboard, Port 4 eth4 Intel Dual Port Card, Port 1 (Rightmost Port) eth5 Dual, Port 2 eth6 Intel Quad Port Card, Port 1 (Leftmost Port) eth7 Quad, Port 2 eth8 Quad, Port 3 eth9 Quad, Port 4
