NAME
       scsi_hba_init, scsi_hba_fini - SCSI Host Bus Adapter system initialization and completion routines

SYNOPSIS
       #include <sys/scsi/scsi.h>

       int scsi_hba_init(struct modlinkage *modlp);

       void scsi_hba_fini(struct modlinkage *modlp);

INTERFACE LEVEL
       Solaris architecture specific (Solaris DDI).

PARAMETERS
       modlp	       Pointer to the Host Bus Adapters module linkage structure.

DESCRIPTION
   scsi_hba_init()
       scsi_hba_init()	is the system-provided initialization routine for SCSI HBA drivers.  The scsi_hba_init() function registers the HBA in the
       system and allows the driver to accept configuration requests on behalf of SCSI target drivers. The scsi_hba_init() routine must be  called
       in  the HBA's _init(9E) routine before mod_install(9F) is called. If mod_install(9F) fails, the HBA's _init(9E) should call scsi_hba_fini()
       before returning failure.

   scsi_hba_fini()
       scsi_hba_fini() is the system provided completion routine for SCSI HBA drivers. scsi_hba_fini() removes all of the  system  references  for
       the HBA that were created in scsi_hba_init(). The scsi_hba_fini() routine should be called in the HBA's _fini(9E) routine if mod_remove(9F)
       is successful.

RETURN VALUES
       scsi_hba_init() returns 0 if successful, and a non-zero value otherwise. If scsi_hba_init() fails, the HBA's  _init()  entry  point  should
       return the value returned by scsi_hba_init().

CONTEXT
       scsi_hba_init() and scsi_hba_fini() should be called from _init(9E) or _fini(9E), respectively.

SEE ALSO
       _fini(9E), _init(9E), mod_install(9F), mod_remove(9F), scsi_pktalloc(9F), scsi_pktfree(9F), scsi_hba_tran(9S)

       Writing Device Drivers

NOTES
       The  HBA  is  responsible for ensuring that no DDI request routines are called on behalf of its SCSI target drivers once scsi_hba_fini() is
       called.
