Back to Basics - Create a LUN and present it as a Cluster Shared Volume

You know when you do something and you think to yourself "Oi, I should really document this"?  And then you go "Nahhh, this is easy peasy lemon squeezy - I won't forget" and a month later you have to repeat the task and wonder of wonders, you did forget.  Well Goddammit - never will I have to wonder again how to create a LUN on a HP EVA 4400 SAN and use said LUN (or Vdisk in vHP's vVirtual vSpeak vWhere vEverything vStarts vWith a vStupid vV). vWhere...er I mean where was I.  Ahh yes, lets create a vDisk...

Create a vDisk on the EVA SAN

1. Log into Command View (what a cool name, sounds like you can bomb some backwater country into the Stone Age with a mere misplaced mouse-click)
2. Expand your Virtual Disks Folder
3. Click Create vDisk
4. Name your disk, then give it a size and RAID level
5. Click Create vDisk

Present the vDisk to your Hosts

1. Navigate to your newly created vDisk and click the Presentation tab
2. Click Present and select all hosts to present the vDisk to.  For some obscure reason every 4400 I've worked on would only allow me to present to four hosts / HBA's at a time, anything more and it errors out

Initialise and format the vDisk

1. Open the Disk Management MMC on one of your SAN-connected Hyper-V hosts
2. Right-click the Disk Management node and click Rescan on the context menu
3. Right-click on the newly appeared unallocated disk and select Bring Online
4. Right-click the disk and click Initialize
5. Right-click (how's that middle finger doing?) on the unallocated storage and click Create Simple Volume
6. Complete the wizard, but do not assign a drive letter

Create a Cluster Shared Volume using our vDisk

1. Open Failover Cluster Manager
2. Go to the Storage node and click Add a Disk in the Actions pane
3. Select the disk you wish to add and click OK
4. Right-click the Disk and click Properties - now give it a descriptive name.  Because I say so
5. Go to Cluster Shared Volumes and click Add Storage in the Actions pane
6. Select the disks you wish to add and click OK
7. The CSV will now magically appear in your ClusterStorage namespace.  Navigate there and give it a descriptive name
8. You've just greated a CSV full of win, which can now host a highly-available VM!
