Dell PowerVault 3000 / iSCSI virtual disks won't initialize due to "incorrect function"

I just loaded my Dell PowerVault 3000i with 7000 more GB of space and would like to use it.  I can create virtual disks and link them to a disk group, but ONLY ONE virtual disk will initialize.

I keep getting a dialog pop-up from Logical Disk Manager that says, "Incorrect function."

It doesn't matter whether I make 2, 3, or 4 virtual disks, I can only initialize one or two the virtual disks.

LUN numbers are assigned started at 0 and are assigned 0 and 1 for two disks.  0, 1, and 2 for three disks and so on.  There doesn't seem to be any rhyme or reason as to which one or two volumes work.  I just did a test of 4 volumes and the 2 and 4th virtual disks were okay, but the 1st and 3rd gave the "Incorrect function" error when I attempted to put them Online or Initialize them.

Restarting the VM doesn't help me at all.

did you load the dell mpio?

in MDSM check and ensure that the ownership/prefered path slots are the same as in the Microsoft iScsi initiator.

I've only done this one other time, so I'm not sure what the Dell MPIO is.  Is that the Dell version of iSCSI initiator?

In any case, it does look like it's an ownership issue.  It seems like it switched to the other controller (controller 1) for each virtual disk I made.  Is it doing it that way to be more fault tolerant or something or do I have things setup incorrectly?

I had to switch them all to controller 0 to get them to work.

Each LUN has to be on its own subnet (this is a powervault item).. http://www.cns-service.com/equallogic/pdfs/TR1036-MPIO_EQLX-DSM.pdf
