I am very new to multipathing concept. I am trying to troubleshoot an issue with multipathing however, I am not sure if it's an issue with multipath configuration.
Server is connected to storage over iscsi, there are 4 different Ethernet ports which are connected to server for storage connection. Eth1 and Eth2 : 192.x.x.x (2 IP's in same subnet) Eth5 and Eth6 : 10.x.x.x (2 IP's in same subnet) these ip's are not in any vlan.
None of the Ethernet card IP config have gateway. I think it's working on broadcast.
Here is the configuration on server for multipath.
device
{
vendor "NETAPP"
product "LUN"
path_grouping_policy group_by_prio
features "0"
prio "ontap"
path_selector "round-robin 0"
failback immediate
hardware_handler "0"
rr_weight uniform
rr_min_io 128
}
Post running this command "iscsiadm --mode session" I am only able to see 2 paths i.e Eth5 and Eth6. why I am unable to see path for Eth0 and Eth1 Should be able to see 4 paths or 2 paths are correct. I have checked messages, unable to find anything.
Kindly advise, If above configuration is correct or If wrong, what things need to correct.
Thank you.
