 From the minutes of the CAP working group, agenda item 4.6:

"In a related issue the initiator and target device names in a SCSI 
target/initiator device will be combined to form a single name, subject to 
the one per protocol rule as well."

This does not work for SBP; I also suspect that it is, on general 
principal, ill-advised since initiator and target functionality are 
orthogonal to each other. In representative software stack implementations 
for PCs, initiator and target code may be completely unaware of each other.

I suggest that separate initiator and target names continue to be 
maintained, as they have in the past. A subsequent excerpt from the CAP 
minutes, reproduced below, seems to indicate ample precedent for 
maintaining separate names.

"George also asked if the target/initiator device initiator port name and 
target port name can be combined in a single name. Jim Hafner responded by 
noting that both iSCSI and SRP have different name definitions for 
initiator and target ports, resulting in the need for separate, different 
names in the architecture model."
