    New iSER Driver installation on ESXi 6.5-U1




      We have tried to install the new iSER driver (MLNX-NATIVE-ESX-ISER_1.0.0.1-10EM-650.0.0.4598673.zip) on ESXi 6.5 U1.

      But only the software iSCSI shows up in the storage adapter list. The iSER adapter is not visible.


      The configuration is as follows:


      • - Servers: PowerEdge R720, Cisco C-240 M3 and Lenovo RD650 128 to 192GB RAM.
      • - Dual Xeon
      • - Mellanox ConnectX-3 MCX354A-FCBT adapters

      • iSER Module.PNG


      • - ESXi 6.5-U1 Build 5969303
      • - Mellanox Drivers native drivers

      The installation of the new iSER drivers is successful and we have issued the following command to ensure that the driver is loaded on boot:

      # esxcli system module set --enabled=true --module=iser

      All the hosts boot normally and

      # esxcfg-module -g iser


      iser enabled = 1 options = ''

      However just to check, after booting if we issue the following command the first time:

      # vmkload_mod iser

      We get:

      Module iser loaded successfully

      Which leads to believe that the module was not loaded automatically

      Launching the same command a second time leads to:

      vmkload_mod: Can not load module iser: module is already loaded

      On all 5 hosts we are not able to see the iSER adapter even after several reboots.

      The network adapters are connected to a vDS:

      Any clue or procedure to clean install everything in order to bring up the iSER adapter ?

      Thanks !
