CDB: 12 20 0 0 24 0 (probe6:arcmsr0:0:16:1): CAM status: Unable to terminate I/O CCB request (probe6:arcmsr0:0:16:1): Error 5, Unretryable error (probe6:arcmsr0:0:16:2): INQUIRY. CDB: 12 40 0 0 24 0 Which is defined in sys/cam/cam.c .... as CAM_UA_TERMIO, but that error is nowhere set in the arcmsr code.... So I clearly do not yet know enough to hellp in this. --WjW For all of the ports on the adapter.
