After you set up initiator access to the LUN group, you must initialize and format each LUN in the LUN group. For more information see the How do I configure an iSCSI initiator on my ReadyNAS OS 6 storage system?

The following procedure uses the Microsoft iSCSI Software Initiator, which is freely available online and is integrated in Windows 7.

Note: If you use an operating system other than Windows, the steps are different, but the basic tasks remain the same.

To initialize and format LUNs in the LUN group:

1. Open the Windows Disk Management application.

Each LUN in the LUN group displays as an unallocated disk that needs to be initialized and formatted.

Tip: If the disks do not display, select Action > Refresh in the Disk Management window.
