FC_REMOVE_HOST(9) SCSI mid layer FC_REMOVE_HOST(9)NAME
fc_remove_host - called to terminate any fc_transport-related elements for a scsi host.
SYNOPSIS
void fc_remove_host(struct Scsi_Host * shost);
ARGUMENTS
shost
Which Scsi_Host
DESCRIPTION
This routine is expected to be called immediately preceeding the a driver's call to scsi_remove_host.
WARNING
A driver utilizing the fc_transport, which fails to call this routine prior to scsi_remove_host, will leave dangling objects in
/sys/class/fc_remote_ports. Access to any of these objects can result in a system crash !!!
NOTES
This routine assumes no locks are held on entry.

scsi_hba_init(9F) Kernel Functions for Drivers scsi_hba_init(9F)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.

I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
