I was wondering if anyone could help me. When i Look at a host on our 3par, i can see it has 8 paths but we seem to have duplicates on each port. So i would expect to see 4 paths not 8.

The question is can this cause issues have duplicates as we've been having issues with this host. I'm also not saying all our hosts have this issue, just a few.

You have 4 nodes with 2 Ethernet ports each, so each host has 8 paths.

I understand the 4 nodes. but the 2 connections on each node are on the same port on each, i can understand 2 connections to a node but on different ports on those nodes.

or am i missing something?

Maybe your host got 2 IPs and each of these IP sees 4 ports ?

at the end of the day, if you look at the screenshot, it says "host ports: 1" and "storage system ports: 8"

so 1 host port talking to 8 storage system ports equals 8 paths.

1 host port, ok. I would say 1 IQN.
On ESX you can set an iqn for each ethernet adapter connected to storage or one iqn for the host.

I'm wrong ?
