MEM 1.5 and ESXI 6.5 Path Status "not used"

Hello,

I am administering a network consisting of 14 hosts and 10 EqualLogics. One of our hosts is unable to connect to our SAN. The host is a Dell r710 with ESXI 6.5 U2 and MEM 1.5 installed. The host is assigned to a distributed switch for isci traffic. The uplinks are assigned to the port groups and are compliant but the Path Status under Network Port Binding is appearing as Not Used. The 6 datastores that are available are not showing up. What can be done to correct the multipathing? 

I am able to ping the group master from each vmkernel adapter. ping -I vmk1 10.10.90.x. Below is some configurtion of the host, if anything else is needed please let me know and I can certinly add it.

Re: MEM 1.5 and ESXI 6.5 Path Status "not used"

Hello Seth, In order to do MPIO with EQL arrays, the VMKernel ports must be bound to the iSCSI adapter. EQL uses a flat IP subnet, so there should be two NICs and two VMKernel ports configured for MPIO to properly function. EQL doesn't support bonding or trunking of ports. MEM does not replace the MPIO or iSCSI initiator in ESXi. It enhances it to work more efficiently with EQL storage. The basic iSCSI setup must be working first before MEM can be used. Also the errors you included aren't related to ISCSI Wrong adapter. vmhba0:C0:T1:L0 Regards, Don
