Hello,
Is there a way to disable an "offload iface" ?
On my Centos 5.7 serveur (ProLiant DL380 G7) + EMC VNX 5300
I have 4 build-in NIC :
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit
Ethernet (rev 20)
03:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit
Ethernet (rev 20)
04:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit
Ethernet (rev 20)
04:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit
Ethernet (rev 20)
The first 2 ones are bonded and connected to the regular network (eth0, eth1)
ip addr sh eth0
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
master bond0 qlen 1000
link/ether d4:85:64:75:d9:d4 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
master bond0 qlen 1000
link/ether d4:85:64:75:d9:d6 brd ff:ff:ff:ff:ff:ff
The other 2 are on 2 ISCSI network (for failover)
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc pfifo_fast qlen 1000
link/ether d4:85:64:75:d9:d8 brd ff:ff:ff:ff:ff:ff
inet 10.0.0.237/24 brd 10.0.0.255 scope global eth2
inet6 fe80::d685:64ff:fe75:d9d8/64 scope link
valid_lft forever preferred_lft forever
5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc pfifo_fast qlen 1000
link/ether d4:85:64:75:d9:da brd ff:ff:ff:ff:ff:ff
inet 10.0.1.237/24 brd 10.0.1.255 scope global eth3
inet6 fe80::d685:64ff:fe75:d9da/64 scope link
valid_lft forever preferred_lft forever
For each of them I create another IP for the iscsi layer :
[root@lucca ifaces]# iscsiadm -m iface
default tcp,<empty>,<empty>,<empty>,<empty>
iser iser,<empty>,<empty>,<empty>,<empty>
bnx2i.d4:85:64:75:d9:db bnx2i,d4:85:64:75:d9:db,10.0.1.37,<empty>,<empty>
bnx2i.d4:85:64:75:d9:d9 bnx2i,d4:85:64:75:d9:d9,10.0.0.37,<empty>,<empty>
bnx2i.d4:85:64:75:d9:d7 bnx2i,d4:85:64:75:d9:d7,<empty>,<empty>,<empty>
bnx2i.d4:85:64:75:d9:d5 bnx2i,d4:85:64:75:d9:d5,<empty>,<empty>,<empty>
As we can see, we see all 4 NIC, is there a way to disable the ones used for
regular network ?
