UNIX for Dummies Questions & Answers

hi guys

This is suse 11 sp1

I have a Server that has 4 NICs, I've created 2 bonds
bond0(eth0-eth1) - 10.10.10.2
bond1(eth2-eth3) - 10.10.10.3

Each bound goes to a Storage Device which is directly connected
so bond0 goes to Storage_Controller_1 and 2 like this

Server_bond0 <--------> Storage_Controller_1 (10.10.10.4)

Server_bond1 <--------> Storage_Controller_2 (10.10.10.5)

The problem is when I ping from server to Storage it looks like only bond0 is active and since bond0 is direclty connected to Storage_Controller_1 it will only ping 10.10.10.4

is there a way to make both bonds independent so
communication between bonds and storage 1 and 2 are separate?

also I attached a computer to this server and that hub (just for testing) and found this is from a windows box an arp command

Code:

C:\Documents and Settings\admin>arp -a
Interface: 10.10.10.100 --- 0x2
  Internet Address      Physical Address      Type
  10.10.10.2            00-0c-29-dc-10-ca     dynamic
  10.10.10.3            00-0c-29-dc-10-ca     dynamic

if fact If I disconnect cables from bond1 ip 10.10.10.3 this IP will be still pingable

any idea how to seperate this so
bond1 will respond to the IP is belongs to and the same for bond0

thanks a lot

Tried this not working

Code:

net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2

net.ipv4.conf.default.arp_filter=1
net.ipv4.conf.all.arp_filter=1

any other idea?

any guidance

thanks

guys

I am getting there

this does what I want

iproute2

Code:

echo 200 storage_table >> /etc/iproute2/rt_tables
ip rule add from 10.10.10.3 table storage_table
ip route add 10.10.10.0/24 via 10.10.10.3 dev eth1 table storage_table

sysctl parameters

Code:

net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2

but I need to make this changes permanent after reboot
where I should add them?
I already tried /etc/init.d/boot.local but no luck

Code:

echo 200 storage_table >> /etc/iproute2/rt_tables
ip rule add from 10.10.10.3 table storage_table
ip route add 10.10.10.0/24 via 10.10.10.3 dev eth1 table storage_table

any idea?
thanks

Not sure how this works in SUSE, but could you add the commands in a post-up statement in the interface conf file?
