I am currently researching device behavior with respect to N_Port login 
and was wondering if anyone can provide clarification.
Q: If an already-logged-in N_Port performs login again (via PLOGI), is 
this considered an I_T nexus loss as defined by SAM-3, 6.3.4?
The ENDL Fibre Channel Bench Reference implies that re-Login causes an 
implicit Logout.  However, I cannot find any supporting information in 
either the FCP-3 for FC-LS specifications.  My goal is to ultimately 
determine whether a SCSI Target Port should set a Unit Attention if a 
SCSI Initiator Port re-logs in.
Thank you for your your help!
