Encountering error in diskpart when creating EqualLogic guest attached volume

Running into something odd when doing the typical addition of a guest attached volume.  Done this several dozen times before, but am running into something odd in a different environment.  Here's the rundown.

  • vSphere 5U1 hosts
  • MEM installed and configured, so it has the typical vmkernel ports (+ heartbeat)
  • 2 additional portrgroups added in that same iSCSI vSwitch made by the MEM
  • Windows 2008R2 (x64) with 2 NICs set for iSCSI guest connections, and with HIT/ME 4.0 installed.
  • Each VM portgroup assigned to their own respective portgroups (in and active/standby arrnagement), per best practices (

    http://en.community.dell.com/techcenter/storage/w/wiki/data-drives-in-vmware.aspx)

  • iSCSI initiator pointing correctly to the group IP
  • Setup Wizard run on the guest VM to establish connections to the Group, and enable inclusion/exclusion of multipathing
  • ISCSI initiator app sees the guest volume fine, and I connect it.
  • Eql group Manager has guest volume ACL set to the IQN of the VM
  • VSS/VDS has an ACL set to the IQN of the VM.

Connectivity through each NIC is fine.  I run Diskpart and "list disk" and the new volume shows up.

I select the disk in diskpart, then run "Create Partition Primary Align=64"  This is where it gets weird.  I get the result of:  "DiskPart has encountered an error:  The media is write protected."  See the System Event Log for more information."

I jump into the event log, and see: "VDS fails to write boot code on a disk during clean operation.  Error code:  80070013@0207008"

Has anyone ever run into this?  I've done this dozens of times and never have had a problem.  I checked and rechecked, and everything looks fine.  The one thing I did notice to which I couldn't remember, was that when I did a "list disk" it did show the volume as "offline" (which I couldn't remember if that was normal or not).  I manually turned it online in diskpart, but that had no affect.  I repeated the entire process, and the same result occured.  Am I overlooking something?

(Moderator:  Feel free to move post to the EqualLogic branch of the forum.  I thought that is where I posted it at, but...)
