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 can access 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 135.
Accessing LUN groups from iSCSI-attached devices requires these high-level steps:
1. Set up iSCSI initiator access to the LUN group.
ReadyNAS OS supports two methods for setting up iSCSI initiator access: manually
configuring both the initiator and the ReadyNAS system for access, or using iSNS.
To use the manual method, see Set Up Initiator Access on page 113. To use iSNS,
see Use iSNS on page 120.
2. Initialize and format LUNs in the LUN group.
See Initialize and Format LUNs on page 120.
Set Up Initiator Access
The following procedure uses the Microsoft iSCSI Software Initiator, which is freely
available online and is integrated in Windows 7 and later.
Note: If you use an operating system other than Windows, the steps are different, but
the basic tasks remain the same.
