Driver Entry Points                                tran_abort(9E)



NAME
     tran_abort - abort a SCSI command

SYNOPSIS
     #include 



      int prefixtran_abort(struct scsi_address *ap,
          struct scsi_pkt *pkt);


INTERFACE LEVEL
     Solaris architecture specific (Solaris DDI).

ARGUMENTS
     ap      Pointer to a scsi_address(9S) structure.


     pkt     Pointer to a scsi_pkt(9S) structure.


DESCRIPTION
     The tran_abort() vector in the  scsi_hba_tran(9S)  structure
     must  be  initialized  during the HBA driver's attach(9E) to
     point to an HBA entry point  to  be  called  when  a  target
     driver calls scsi_abort(9F).


     tran_abort() should attempt to abort the  command  pkt  that
     has  been  transported  to the HBA.  If pkt is NULL, the HBA
     driver should attempt to abort all outstanding  packets  for
     the target/logical unit addressed by ap.


     Depending on the state of a particular command in the  tran-
     sport  layer,  the  HBA  driver may not be able to abort the
     command.


     While the abort is taking place, packets issued to the tran-
     sported layer may or may not be aborted.


     For each packet successfully aborted, tran_abort() must  set
     the  pkt_reason  to  CMD_ABORTED, and pkt_statistics must be
     OR'ed with STAT_ABORTED .

RETURN VALUES
     tran_abort() must return:

     1     upon success or partial success.


     0     upon failure.


CONTEXT
     The tran_abort() function can be called from user or  inter-
     rupt context. This requirement comes from scsi_abort().

NOTES
     If pkt_reason already indicates that an  earlier  error  had
     occurred,  tran_abort() should not overwrite pkt_reason with
     CMD_ABORTED.
