13.7  Defining iSCSI hosts
Defining host using an iSCSI Initiator is slightly different than definition of host with FC or SAS 
HBAâs. In case of iSCSI HW Initiators you can see as many iSCSI host port identifiers as 
iSCSI HBAâs, installed in such a host. In case of iSCSI SW Initiator, you see just one iSCSI 
host port identifier, even if you have more Ethernet cards used for iSCSI in your host server. 
Multiple redundant data paths are presented as multiple iSCSI sessions in this case, as 
described in section 13.5, âView/End iSCSI Sessionsâ on page 329.
Definition of a Host with traditional SAS or FC HBAâs is described in section 11.2, âDefining 
Hostâ on page 283 in detail. In the following sections we show iSCSI host definition 
differences.
13.7.1  View Unassociated iSCSI initiators
A Host definition is provided in Mapping tab of DS Storage Manager. To see if some servers 
with active iSCSI Initiator are available to be defined as a host, you can view unassociated 
host port identifiers. 
Several ways can be used to show unassociated host ports. For example you can select 
Mappings ďŽ View Unassociated Host Port Identifiers in the Subsystem Management pull 
down menu. A new window as in Figure 13-16 on page 334 appears. You can see World 
Wide Port Names for SAS or FC HBA,s if you have some, and if an iSCSI Initiator is already 
configured and authenticated for access to your DS3500 subsystem, you see IQN name of
