Appendix B: Preparing Storage for Your VMs
Use the following procedures to prepare a raw disk for a VM after a LUNs has
been provisioned to the parent partition. Dell recommends that you provision
one LUN at a time and complete the configuration before provisioning
additional disks to avoid selection of the incorrect disk
Preparing the Disk for Use as a Passthrough Disk
1 Using Disk Management or diskpart (for systems running Server Core),
confirm that the parent partition recognizes the provisioned disks, and
that they have been initialized and are in the offline state.
If using
diskpart , perform the following commands in order:
a LIST DISK (note the newly provisioned disk number)
b SELECT DISK X (where X is the disk number)
c ATTRIBUTES DISK CLEAR READONLY
d ONLINE DISK
e CONVERT GPT (initializes the disk)
f OFFLINE DISK
2 If the disk is to be utilized for a highly available VM, make the disk a
cluster resource.
3 Present the disk to the virtual machine using Hyper-V Manager.
