NAME

       tran_abort - abort a SCSI command

SYNOPSIS

       #include <sys/scsi/scsi.h>

	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 transport layer, the HBA driver may not be able to abort the command.

       While the abort is taking place, packets issued to the transported 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.

NOTES

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