Access LUN Groups from an iSCSI-Attached Device
An iSCSI initiator application lets you set up a connection from a server to a LUN group (and
therefore to individual LUNs). Normally, users would not initiate such a LUN connection. The
network administrator would provide access to a LUN group through a server.
The iSCSI targets (that is, the LUNs in the LUN group on the ReadyNAS) present themselves
on the client system as virtual block devices and can be treated as a locally attached disks.
Windows, for instance, can run FAT32 or NTFS on the iSCSI target device and treat the
devices as though they were locally attached.
When they have access to a LUN group, users can employ any backup application to back
up local data from their iSCSI-attached device to a LUN.
Note: Unlike snapshots that reside on a share, snapshots that reside on a
LUN are not visible to users. For information about how to recover
data using a snapshot on a LUN, see
Recover Data from a
Snapshot to an iSCSI-Attached Device on page 149.
Accessing LUN groups from iSCSI-attached devices requires these high-level steps:
1. Set up iSCSI initiator access to the LUN group.
See Set Up Initiator Access on page 116.
2. Initialize and format LUNs in the LUN group.
See Initialize and Format LUNs on page 122.
Set Up Initiator Access
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 set up initiator access:
1. Open the iSCSI initiator and click the Configuration tab.
