Hello,
Thank you for the work. This is my 1st post here.
Under a Debian OS, i try to acces by two different paths an Equallogic
PS 6000.
On the server i configured two NICs
eth1 Link encap:Ethernet HWaddr b8:ac:6f:12:38:c9
inet adr:192.168.15.11 Bcast:192.168.15.255 Masque:
255.255.255.0
eth2 Link encap:Ethernet HWaddr b8:ac:6f:12:38:cb
inet adr:192.168.15.12 Bcast:192.168.15.255 Masque:
255.255.255.0
On the same vlan than the SAN
First, the discovery works fine:
iscsiadm -m discovery -t st -I eth1 -I eth2 -p 192.168.15.1 -P 1 -o
delete -o new
Target: iqn.2001-05.com.equallogic:
0-8a0906-0dd652407-00e000e7b254c345-testdeb
Portal: 192.168.15.1:3260,1
Iface Name: eth2
Iface Name: eth1
With EQL, there is only one IP address for the portal, regardless of
how many times i have to access it.
I try to connect via the two nics:
First one:
#iscsiadm -m node --targetname iqn.2001-05.com.equallogic:
0-8a0906-0dd652407-00e000e7b254c345-testdeb -I eth1 --portal
192.168.15.1:3260,13 --login

All is fine with the first one.

With eth2,, nothing happens.

I don't have any log line
Is anyone an idea of what could happen ?
Thank you very much, i am stuck
Can you try changing the following /etc/sysctl.conf parameter
net.ipv4.conf.default.rp_filter = 0
To be more clear you would need to change the rp_filter value to 0
Run "sysctl -p" after changing this to have the change reflected in
the kernel.
Mike Christie elucidated in an earlier post that the strict source
routing requirement that some distributions impose can cause the login
through multiple ifaces to fail.
