SCSI/FC Target Drivers
The supported Fibre Channel adapters do match each other.
Two-channel Adapters
Some adapters are designed as two-channel model so they are recognized by OS as two single-channel
adapters. Device Manager shows two adapters, their Properties are, for example, PCI slot 2, Bus 1,
Function 0 and PCI slot 2, Bus 1, Function 1 (note that the only difference is Function value).
For the Scalar DLC it means that it is technically possible to use single two-channel SCSI/FC adapter in
both Initiator mode (Channel A / Port 1 - Function 0) to connect to the library medium changer, and in Target
mode (Channel B / Port 2 - Function 1) to connect to the SCSI Client host (see
Figure 63
on page 117). And
of course, such two-channel adapters can be used for two different SCSI Clients, as if these clients were
connected to the two different SCSI/FC target adapters, or as two single-channel initiator adapters if
required.
Note
The Local SCSI Target driver is added for emulation the SCSI Target features on a PC
without appropriate SCSI adapter. In the Management GUI, under the SCSI Target tab,
the Local SCSI Target port appears, so the Target objects can be created and assigned
to the SCSI Clients.
However, this port is not reflected in the SCSI Target Port Tool because this utility shows
only adapters that could operate either as Initiators or as Targets. Local SCSI Target
only emulates the adapter port and sure cannot operate in Initiator mode.
