Windows Shared Disk Array Path Definitions

On Windows, access shared disks through absolute paths or the Disk Physical number, as shown in these examples.

Use the Disk Physical number. For example:
\\\\.\\PhysicalDrive1
\\\\.\\PhysicalDrive2
\\\\.\\PhysicalDrive3
Use absolute paths using drive letters. For example:
x:\main
y:\userdb1
z:\userdb2
Using the drive letters limits the number of disks to fewer than 26, so the first method is better.
