resolved – bnx2i dev eth0 does not support iscsi
There's a weird incident occurred on a linux box. The linux box turned not responsible to ping or ssh, although from ifconfig and /proc/net/bonding/bond0 file, the system said it's running ok. After some google work, I found that the issue may related to the NIC driver. I tried bring down/bring up NICs one by one, but got error:
Bringing up loopback interface bond0: bnx2i: dev eth0 does not support iscsi
bnx2i: iSCSI not supported, dev=eth0
bonding: no command found in slaves file for bond bond0. Use +ifname or -ifname
At last, I tried restart the whole network i.e. /etc/init.d/network restart. And that did the trick, the networking was then running ok and can ping/ssh to it without problem.
