If only an I_T nexus has been established, the target shall go to the BUS FREE phase. No status or message shall be sent for the current I/O process and no other I/O process shall be affected.
( The ABORT message in the case of only an I_T nexus is useful to an initiator that cannot get an IDENTIFY message through to the target due to parity errors and just needs to end the current connection. Any pending data, status, or queued I/O processes for the I_T nexus is not affected. ) ( It is not possible to abort an I_T nexus on a reconnection because of item f) in 6.2.1. )
It is not an error to issue this message to an I_T_x nexus that does not have an active or queued I/O process.
Previously established conditions, including MODE SELECT parameters, reservations, and extended contingent allegiance shall not be changed by the ABORT message.
( The BUS DEVICE RESET, CLEAR QUEUE, ABORT, and ABORT TAG messages provide a means to clear one or more I/O processes prior to normal termination. The BUS DEVICE RESET message clears all I/O processes for all initiators on all logical units and all target routines of the target. The CLEAR QUEUE message clears all I/O processes for all initiators on the specified logical unit or target routine of the target. The ABORT message clears all I/O processes for the selecting initiator on the specified logical unit or target routine of the target. The ABORT TAG message clears the current I/O process only. )
