Steps to setup MPIO round robin and DSM with P4000 / Lefthand nodes

This example is windows 2008 with 2 x 1gbit nics

Install HP DSM driver onto windows 2008 (this should also install MPIO feature on windows 2008)
Setup 2 x IP’s on windows host - storage subnet (used with MPIO)
1. Confirm you can ping target from both (enable one at a time - ensure there is no routing on your other nics)
Provision storage and allow server read / write access to windows server (via initiator name)
Open iSCSI on windows 2008
Put in IP of target in discovery tab
On first tab confirm that iSCSI drive is presented to host
Click “connect” - check both auto-connect and use MPIO
1. click advanced - chose MS iSCSI initiator, choose first IP and target IP. Click o.k. / o.k
2. click advanced - chose MS iSCSI initiator, choose second IP and target IP. Click o.k. / o.k
3. Repeat above per additional Nic
Confirm via “devices” that there is x (as many targets as nics) targets per disk
1. Within devices choose MPIO - change from vendor specific to “round robin”
  1. Note : read / write access to LUN is required when using “round robin” MPIO opposed to the default “vendor specific” which works with read only access. Else you will get an error - “not supported”
2. Repeat above per “device”
Confirm on Lefthand / P4000 CMC that the LUN has one connection per initiator Nic, and that each connection also has its DSM children (visible in CMC if working).

Confirm that the connection are as expected…
