10.14 Selection without ATN
If the target is selected without A T N signal active, no Identify message is received from the initiator. In this
case, the L U N is identified from the CDB and disconnect permission is disabled.
The target does not
perform any phase retries. The target still responds to a subsequent attention condition. However, the L U N
is not considered to be known if a fatal error is detected during the Command phase. That is a Command
phase parity error or a fatal message error in response to attention condition during Command phase is
handled as a Bus Free error with no sense data. The target also knows the use of linked commands if
selected without ATN.
Phase retries may be allowed if a subsequent Identify message is received.
10.15 Multiple Initiator Environment
10.15.1 Initiator Sense Data
Separate sense data is reserved for each I-T-L. Each sense data is maintained independent of commands
from other initiators.
10.15.2 Initiator Mode Select/Mode Sense Parameters
A single shared copy of the Mode Select/Mode Sense parameters is maintained by the file. This includes
both the current and saved parameters.
10.15.3 Initiator Data Transfer Mode Parameter
A separate data transfer mode parameters area is reserved and maintained for each initiator.
