The iSCSI Initiator and Authentication
Authentication is not required for the HP D2D, but it is supported for those companies that have an
IT policy that requires them to use authentication. If this is the case, you will need to configure the
necessary fields on the iSCSI Initiator and also ensure that the corresponding information is supplied
in the Web Management Interface. This enables the Initiator to log into the target device on the HP
D2D and the target device to log into the Initiator.
The authentication method supported on D2D products is CHAP. It relies on a "secret" known only
to the target and initiator. The size of the CHAP secret is between 12 and 16 characters, and must
be entered in exactly the same format in both the Web Management Interface and the iSCSI initiator.
An 'Authentication Failure' message will occur if the same 'secret' and 'user name' information are
not entered into the iSCSI Initiator screen and the Web Management Interface. Further details on
authentication and CHAP can be found within standard iSCSI protocol documentation.
The recommended process if you wish to enable authentication is:
1. Create the devices on the Web Management Interface.
2.
Set up the Targets in the iSCSI Initiator.
3. Connect to the devices using the CHAP user name and secret that you configured on the Targets
tab.
The Microsoft iSCSI Initiator
The Microsoft iSCSI initiator contains a number of tabs. This section describes the information that
must be provided in order to connect the host to a device on the HP D2D Backup System. It does not
provide a comprehensive description of all the tabs; please download the “User Guide” from the
Microsoft website for more information.
General tab
You do not normally need to make any changes on the General tab. The Initiator Node Name is
generated automatically, which guarantees that it will be unique on your network.
