Hi there.
I have configured a new vSwtich on my vmserver to handle iSCSI traffic. within the vSwitch i have 4 VM kernels each with thier own active NIC and IP on the iSCSI network.
I have mounted my new vm datastore using Dell's MEM plugin and this works great.
Within my iSCSI initiator properties, taking a closer look at the VMKernel Port bindings i can see that only 2 of the NIC's are currently in use and active. The other 2 NIC's Path status is 'Not Used'.
This is the same when looking at the properties of my iSCSI vm datastore. The Paths shown are my two Active NIC's with the correct status of 'Active (I/O)', but the other 2 NIC's are not being used?
I'm not sure if vSphere is able to use 4 active NIC's for this or not? Are the other 2 NIC's used as standby automatically or do i need to select them as standy NIC's within the iSCSI vSwitch?
Thanks,
J.
Hi,
I am also facing the same issue. Please let me know if you were able to find any solution.

wht is the policy set for multipathing?
Round robin

all 4 nics connected to same physical swicth?
No.
two NICs connected through One switch(subnet 1) and another two nics connected to another switch (subnet 2).

Which are the two active paths? Are they on the same vSwitch and subnet or different?
Active paths are showing on the same subnet. (I have 3 ESXi 5.0 hosts and for all of them only one subnet is showing as the active path.)
Here is the screenshot how it is configured. I have mapped eacch vmkernel port to appropriate active NIC

What do you see on the Dynamic and Static discovery tabs? Are the iSCSI SAN visible on both subnets?
Yes, iSCSI SAN is visible on the both the subnets. All the 4 targets displayed.

This looks good. You are sure the SAN is configured correctly and also supports active-active?
Using Dell PV MD3600i- and configured by the book (as per the deployment guide). I guess it is Active/Passive SAN. But following is a statement from Deployment guide:
MEM is only for Equallogic, not for PV.
I suppose that he has Eql.
By default MEM enable only two sessions. To have 4 use this command:
esxcli equallogic param set -n=MemberSessions -v=4
It turns out to be the issue with how I arrange the NICs. It works perfect for me when I group the NICs with same subnet into a vSwitch as below:
Now, I am able to see all the 4 VMKnics active and have total 8 paths to each datastore (4 active, 4 standby) and persistent even after reboots.

Hello,
I have teh same issue, but putting the network adapters in the different switches doesn't resolve the issue 😞
any ideas?
Thanks!
