NexentaStor in front of a NetApp FC LUN using MPxIO

leave a comment

  1. Create a Fibre Channel LUN on your NetApp and map it to your NexentaStor machine (I’m using version 3.0.2 in this example). For this example, I’ve created a 10GB LUN on a filer running ONTAP 7.2: 
    netapp01> lun show /vol/nexenta01/lun01/lun
        /vol/nexenta01/lun01/lun      10g (10737418240)   (r/w, online, mapped)

    There are eight paths from our NetApp to our NexentaStor appliance, so the LUN appears eight times on the “qlc” adapter (lines 9-16 below):

    nmc@nexenta01:/$ lunsync
Cleanup obsolete (dangling) device links?  Yes
Re-enumerating LUNs... done.

nmc@nexenta01:/$ show lun
