HP 3000 Enterprise Virtual Array - Manual (Page 98)

The mpx100/100b FC ports do not necessarily have to be connected to the EVA storage controller
to be added to the iSCSI host entry. Upon iSCSI device discovery, HP Command View polls the
mpx100/100b for both FC port WWPNs and adds them to the iSCSI host entry FC port list.
If a single mpx100/100b is discovered as an iSCSI controller (see Figure 43 ), both of its FC ports
will be included in the single HP Command View iSCSI host entry. If two mpx100's/100b's are
discovered (see
Figure 44 ), the single HP Command View EVA iSCSI host entry contains four FC
ports—two from each mpx100/100b.

The mpx100/100b perspective
When an EVA storage system FC port connects to the mpx100/100b, the mpx100/100b creates in
its database a unique iSCSI target name that includes the WWPN of the EVA storage controller port.
This iSCSI target name is used by the iSCSI Initiator to connect to the EVA storage system.
Each EVA FC port must be connected to the mpx100/100b in order for the mpx100/100b to create
an iSCSI target entry (see
Figure 45 ).
