How to setup Multipathing extension module in my host?

This is using Virtualization environment using DELL solution - 2 DELL PowerEdge R720 hosts, 2 DELL PowerConnect 6248 stacking switches, and 1 DELL EqualLogic PS6100E 4u SAN Storage. I just setup the hosts with VMware ESXi 6.0 with Update 01. However, I was told that for Dell solution, I need to setup the DELL Multipathing Extension Module, sort of MPIO on 2 hosts. btw, how to setup this module on both hosts? Do I have to setup this module on PS6100E? please show step-by-step.

Appreciate for your helps.

What is your PS6100E firmware version?

benhansonCommented:
There are several versions of the EQL MEM(Multipath Extension Module)  Version 1.2 is only compatible with VMWare up to 5.5.  Since you are at ESXi v6.x, you need MEM version 1.3.  Version 1.3 requires your EQL 6100E be at firmware version 7.x.  Once you have EQL at v7, the instructions for install are at the Equallogic support site, though I believe you need to register to get to them.

General instructions are that you download the MEM and upload it to an datastore local to the ESX host.  Here is the command snippet from the instructions:

esxcli --server=hostname software vib install --depot <bundlepath>

Open in new window


The --depot parameter specifies the path to the offline bundle file containing the multipathing plugin
(dell-eql-mem-esxn-version.zip).
NOTE: To install the offline bundle, first copy it to a location that is accessible from the ESXi host. The install command can then be run from any esxcli client, giving the full path to the bundle on the host.
For example, if you upload the bundle to a datastore named datastore1, you can then install it with the following command:

$ esxcli --server 192.168.XXX.XXX software vib install --depot /vmfs/volumes/
datastore1/dell-eql-mem-esx5-1.3.0_356034.zip

Open in new window

So you should be good to go with the install.  Are you already in production?  I believe it is a maintenance mode install.  It's actually pretty straightforward and there's nothing to do on the EQL side, other than having multiple network cards functioning.

Hi Benhanson,

Give me some time to read through the few articles. I will get back to you.

and make sure you have designed your iSCSI network as per my EE Article

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

also enable Jumbo Frames

HOW TO: Enable Jumbo Frames on a VMware vSphere Hypervisor (ESXi 5.0) host server using the VMware vSphere Client

Both the procedures are the same for ESXi 6.0.

and make sure you install the MEM VIB!

Hi both,

Thanks for the articles and suggestions.

All the jobs, such as, create the iSCSI multipathing network, set the jumbo frames, and MEM are done.

However, I can't verify the MEM setup. When I run the command "./setup.pl --server=192.168.1.1 --query", an error message popped up, saying "no permissions".

I copied the whole MEM folder into /vmfs/volumes/datastore1/Drivers/MEM. Any reason why?

You need to just import the VIB.

I'm not sure what setup program you are running. I don't remember using this.

you use the esxcli command to install the vib

 esxcli software vib install --depot /vmfs/volumes/vmfsvol/dell/dell-eql-mem-esx5-1.1.2.292203.zip

(this is the older version!, you need to change the filename for your version)

I've found a web page here, which shows how to do it

http://vninja.net/virtualization/installing-dell-equallogic-multipathing-extension-module-mem-vsphere-5-1/

and you use the esxcli command to verify it's installed.

First, you can run:

esxcli storage nmp psp list

Open in new window


and you should see "DELL_PSP_EQL_ROUTED" in the list of available PSP's.  Then you can verify that all of your datastores are actually using that PSP by running:

esxcli storage nmp device list

Open in new window


This will spit out a summary of all your datastores, including what PSP they use.
