The LUNs are displayed on the Windows host as basic disks under Veritas Enterprise
Administrator.
Accessing LUNs on hosts that use the native OS stack
To access a LUN when you are using the native OS stack, you must make the LUN visible to
the Windows host. Complete the following steps:

folder open, check the lower right pane. Verify that the newly created LUN is visible as a
disk on the host.
Overview of initializing and partitioning the disk
You can create one or more basic partitions on the LUN. After you rescan the disks, the LUN
is displayed in Disk Management as an Unallocated disk.
If you format the disk as NTFS, be sure to select the Perform a quick format option.
The procedures for initializing disks vary depending on which version of Windows you are
running on the host. For more information, see the Windows Disk Management online Help,
which is available at this website:
