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?

Hi Benhanson,

7.1.5

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 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.

Thanks for both experts, in providing the relevant and best suggestions and commands. The Equallogic is working perfectly with MEM installed successfully.
