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.
