NAME

       blk2scsa - SCSA block device emulation

DESCRIPTION

       The blk2scsa module provides support services for generic block devices so that they appear to the system as devices on a virtual SCSI bus,
       thus allowing them to be serviced by the sd(7D) SCSI disk driver. The blk2scsa device supports the SCSI-2 command  set  for  Direct  Access
       Devices.  The  blk2scsa device supports multiple LUNs per physical device and creates a separate child device for each LUN. All child nodes
       attach to sd(7D).

DEVICE SPECIAL FILES

       Disk block special file names are located in /dev/dsk. Raw file names are located in /dev/rdsk.	See sd(7D).

IOCTLS

       See dkio(7I)

ERRORS

       See sd(7D).

FILES

       Device special files for the storage device are created in the same way as those for a SCSI disk. See sd(7D) for more information.

       /dev/dsk/cntndnsn

	   Block files for disks.

       /dev/rdsk/ctndnsn

	   Raw files for disks.

       /kernel/misc/blk2scsa

	   32-bit ELF kernel module (x86).

       /kernel/misc/amd64/blk2scsa

	   64-bit ELF kernel module (x86).

       /kernel/misc/sparcv9/blk2scsa

	   64-bit ELF kernel module (SPARC).
