SCSI0 is LSI Logic SAS since we are only putting the OS and backup
VMDKs on this adapter. For configurations in which we would put a
VMDK-hosting DB or log data, we would make this a Paravirtual SCSI
adapter. For more information on the differences between the LSI Logic
SAS and Paravirtual SCSI adapter and when to use them, read Chapter 6 .

Now we are going to log in to our SQL VMs and configure the newly added storage.
After logging in, navigate to the Disk Management utility.
Tip
From a PowerShell prompt, type diskmgmt.msc to open the Disk Manager utility.
The recently added disks need to be brought online and initialized. Right-click each of
the newly added disks and select Online . After bringing all the added disks online,
right-click one of newly added disks and select Initialize Disk . A wizard opens; ensure
all the newly added disks are selected and select OK .
After the disks have been initialized, it is time to assign them drive letters. Before
clicking a disk, make sure you understand what the disk's purpose is so you can ensure
proper labeling to coincide with your VMDK layout. See Table 11.3 for the layout used.
You will notice we are using the same drive mapping for both virtual machines; ensure
that whatever your drive-letter-naming scheme is, both virtual machines are identical to
one another.
