40 .SS "\fBscsi_hba_init()\fR"
43 \fBscsi_hba_init()\fR is the system-provided initialization routine for
44 \fBSCSI\fR \fBHBA\fR drivers. The \fBscsi_hba_init()\fR function registers the
45 \fBHBA\fR in the system and allows the driver to accept configuration requests
46 on behalf of \fBSCSI\fR target drivers. The \fBscsi_hba_init()\fR routine must
47 be called in the \fBHBA\fR's \fB_init\fR(9E) routine before
48 \fBmod_install\fR(9F) is called. If \fBmod_install\fR(9F) fails, the
49 \fBHBA\fR's \fB_init\fR(9E) should call \fBscsi_hba_fini()\fR before returning
51 .SS "\fBscsi_hba_fini()\fR"
54 \fBscsi_hba_fini()\fR is the system provided completion routine for \fBSCSI\fR
55 \fBHBA\fR drivers. \fBscsi_hba_fini()\fR removes all of the system references
56 for the \fBHBA\fR that were created in \fBscsi_hba_init()\fR. The
57 \fBscsi_hba_fini()\fR routine should be called in the \fBHBA\fR's
58 \fB_fini\fR(9E) routine if \fBmod_remove\fR(9F) is successful.
62 \fBscsi_hba_init()\fR returns \fB0\fR if successful, and a non-zero value
63 otherwise. If \fBscsi_hba_init()\fR fails, the HBA's \fB_init()\fR entry point
64 should return the value returned by \fBscsi_hba_init()\fR.
68 \fBscsi_hba_init()\fR and \fBscsi_hba_fini()\fR should be called from
69 \fB_init\fR(9E) or \fB_fini\fR(9E), respectively.

77 \fIWriting Device Drivers\fR
81 The \fBHBA\fR is responsible for ensuring that no \fBDDI\fR request routines
82 are called on behalf of its \fBSCSI\fR target drivers once
83 \fBscsi_hba_fini()\fR is called.
