hp bl460c g6 with two switch(GbE2c L2/L3 ethernet blade switch for hp c-class bladesystem)

os:rhel5.4_x86_64 windows2008

when take out a fc,linux can't swith the bond0 to another port but window can.

configure is not wrong because it is work on dl380 g6

netstat -i show eth1 is used,but network shutdown when i exec 'ifconfig eth0 down'

why?

Do both interfaces work fine if configured independently without bonding?

It might be useful to see your /proc/net/bonding/bond0 output, and config files.

the wondows2008 work fine with bonding,and other 7 blade with rhel(v4.8 64bit & v5.4 64bit) cant't work with bonding,

the flow is on eth1,eth0 is slave,but after i exec "ifconfig eth0 down", the network is unlink
