IScSI InItIator
Use the iSCSI Initiator feature to use the DataGuard Appliance as an
initiator. This must be done before performing an iSCSI Backup or
restore. To use the iSCSI Initiator function, follow the steps listed below.
Keep in mind that the DataGuard Appliance must have at least one
logical drive acting in the role of a NAS (i.e. LDType = NAS).
1. From the NAS tab, click the iSCSI Initiator menu item, then click
the Create button to open the Create iSCSI Initiator menu.
2. Enter the IP address of the iSCSI target device. If CHAP
authentication is used, enable it by clicking to check mark the
CHAP option box, type the User Name and Password used for
CHAP. Click the Next button to proceed.
3. The new menu lists the IP address and port you just entered for the
iSCSI device. The iSCSI name (IQN) should appear listed here as well.
Enter an Alias Name for the target. The alias name functions as the
name of a folder created in the NAS (initiator) file system. Click the
Save button. The NAS should now be connected to the target. If there
is no file system on the target drive, it will be necessary to format it
before it can be “mounted” or used in the NAS initiator file system.
4. In the main iSCSI Initiator menu, hold your pointer over the listed target
device to reveal the buttons to Connect, Format or Delete. If the target
has been formatted, use the Connect button to mount the target on
the home DataGuard Appliance (initiator). If there is no file system on
the target, it will be necessary to format the drive. See example of an
unformatted target displayed in the iSCSI Initiator menu.
✴ If the drive is not formatted, click the Format button. All data
on the drive will be written over and lost when formatted.
✴ To connect or reconnect to the Target, click the Connect button.
✴ To remove the Target from the NAS file system, click the Delete button.
✴ The newly created iSCSI session will be listed in the iSCSI menu
(click Device > iSCSI > Session tab) for the initiator device. The
added storage can be used for backup of the NAS (see “Backup
to iSCSI” on page 72); or use it as additional storage for NAS
users. Use the Web File Manager to configure user permissions.
The iSCSI connection supports use of AFP, DFS, Samba and
FTP for client connections.
After establishing the iSCSI target connection, a folder appears in file
system of the initiator with the name entered in the Alias Name field.
This folder can be configured just like any other folder using the Web
File Manager plug-in to assign read/write access permissions for users.

Plug-in services provide enhanced server functions. The Web File
Manager is pre-installed to help you create and manage files on the
DataGuard Appliance. Web File Manager is permanently embedded in
the firmware; it can be stopped but cannot be removed. To view the
available function icons for Web File Manager, move your pointer to
the row where it is listed and click on the Open icon.
