My Dell PE 1950 Server have 2 NICs and two is currently connected.
All have bnx2 dirvers. While checking with ifconfig -a, shows eth2 with following out put
However, if I set an IPADDRESS and related parameters in the ifcfg-eth2 and do "ifup eth2"; the system returns
[root@web1 network-scripts]# ifup eth2
SIOCSIFFLAGS: Device or resource busy
Failed to bring up eth2.
(dmesg shows the following output)
[root@web1 network-scripts]# dmesg | grep eth2
eth2: Broadcom NetXtreme II BCM5708 1000Base-T (B2) PCI-X 64-bit 133MHz found at mem d0000000, IRQ 169, node addr 001018393be6
bnx2: eth2: using MSI
ADDRCONF(NETDEV_UP): eth2: link is not ready
How can I debug this issue?. Any pointers are appreciated.
It's telling you link is not ready meaning you don't have a cable plugged into it or the cable is not connected to anything live (e.g. a switch).
You can run ethtool eth2 to get more information on it.
I'm a bit confused though. You say you only have two interfaces - those would typically be eth0 and eth1. Where is eth2 coming from?
If you have a live connection on one interface then moving the cable to the other interface should help you verify whether the cable is the issue or the interface itself.
