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?
